    I love these. Use them all the time with cake decorating and so much easier to remove the tips and change the tip instead of using a new pastry bag. It is the tools like these that make a pastry chefs time easier, less hassles and the tools one needs.

    Anyone who does a lot of pastry work knows the sizes and varieties of tips is infinite. Having the right sized coupler is an absolute if you want to achieve the proper fit and seal to produce the desired results. Nobody beats Ateco's products or Webstuarant's prices!

    Medium size coupler works great by itself for piping out bite size eclairs without needing a special tip attached to it! Cleaning is a breeze.

    This coupler uses good quality plastic. It's very easy to put on and off. The price is just right. I have a lot of Ateco products.

    These 3-piece medium plastic couplers are very nice and professional quality. We've only had them for a few weeks but so far they're holding up great.

    This is a great little coupler for pastry bags! It is a nice, tight seal and fits perfectly on Ateco pastry tips. It comes with two separate sizes so you don't have to buy two.

    Great coupler that fits a lot of different sizes of piping tips. Very versatile and definitely a must buy for the price. So easy to use and great to interchange tips with!!

    i use this coupler by itself because I haven't figured out which size pastry tips it fits. it is perfect for me to use it to fill my cakes.

    from whiskedbymukta Posted on

    Nothing wrong with the quality of this but it is so large that I find it impracticable and I just don not use it. Might be helpful for others.

    from Coco & Mini's LLC Posted on

    The best thing about these medium couplers is the fact that they come with two coupler rings that allow us to conveniently use two different sized pastry tubes.

    Posted on

    A must have tool to make changing tips more convenient. The Ateco 402 is for medium sized tips while the Ateco 400 is for most tips of standard size. The quality of the plastic is solid and think it will take some punishment. The price is right so for convenience sake grab a few for you baking accessory collection.

    If you decorate anything that requires many different variations of icing styles, a coupler is a necessity. It makes it so easy to interchange tips without having to use a new bag.

    This coupler is good for medium sized tips. It fits perfectly. It even has 2 screw on pieces one for the medium tips and one for the large tips

    from Foxland market Posted on

    I really like this plastic coupler. It's very strong and holds the tip very firmly in. Does not pop off like some of the different brand couplers do. Definitely recomend.

    Very nice coupler

    These couplers are a good quality. They are sturdy and thick plastic and seem to hold up long term well . Im pleased with them and will buy again!

    The Ateco 402 3-Piece Medium Plastic Coupler (August Thomsen) is one of the greasiest items I have ever purchased. I had not a clue these even available. You can change the tubes without changing the bag. The price makes this a great value. Highly recommend!

    Posted on

    This coupler is excellent. So much easier to change the tubes. Highly recommend!

    It accommodates medium pastry tubes and can be used with the Ateco 12ā€ or 18ā€ clear disposable pastry bags. Iā€™m a home baker, so I like using tips because I can frost more in less time and get a professional look with minimal effort on my part.

    from j4jcline Posted on

    If you don't already have couplers for your cake piping tips, you should get some. They make changing tips so easy. They are great for when you are decorating a cake and change tips frequently.

    This product is absolutely helpful, easy to assemble and very reasonable price. I have the small and medium sizes and that cover the need in decorating cake and cupcake.

    These connectors are wonderful to work and make changing pastry tips a snap. Being large it holds the bigger tip firmly. Both pieces are Dishwasher safe and clean easy

    from Fragrances on the run Posted on

    This Ateco 402 coupler is great to have on hand for bigger piping tips. I like that it comes with 2 different sized screw on caps for different sized piping tips.

    Posted on

    i bought all 3 sizes of ateco couplers but i use this one most often because most of their piping tubes fit this one. the other sizes are more for specialty tips. but i use all ateco piping pieces so it works great.

    Posted on

    This Atco Cupler for pastry tips is amazing instead of having to keep your pastry tips one bag per tip you just use this and then you switch out your tips as you need them fantastic amazing product

    from N/A Posted on

    Love these very heavy duty couplers to hold my tips. These coupler work for those tips that are larger but not the extremely large tips. I do use them with my disposable bags with ease & security. The price is unbeatable. It's a win-win.

    from Antoinette Bakery Posted on

    Medium plastic coupler are great for any medium sized decorating tips. These are very very sturdy and works as you would expect. Price is great too

    from Tom Posted on

    Inexpensive and they work great. Gone are the days of smelly cloth pastry bags. buy several and have plenty around. Takes seconds to set up in a large ziplock.

    from HomeGrown Eats Posted on

    Medium coupler is a decorators dream. This item allows you to quickly change between tips and get on with the job. Save time and money by not wasting pastry bags by having these on hand

    from Sweet Pea's Cupcakery Cafe Posted on

    Easily switch tips

    Makes icing job easy. I can usually get away without it but prefers to use it. My kids love it than just having the tip on pastry bags by itself.

    Posted on

    This worked well with my Wilton tips and pastry bags. It feels sturdy, well made, and the pieces fit well together. The treads line up perfectly and securely. I am happy with these couplers and will get a lot of use out of them in the future.

    Posted on

    I was a bit disappointed that this one looks to be like the large coupler that Ateco carries. That means (for me) that I reach for it thinking its the large one and the tips wont fit. I'll need to label them.

    These help you attact your paistry bags to your design tips Ateco 402 3-Piece Medium Plastic Coupler (August Thomsen) are dependant on the size of your tips so always get all sizes and for accordingly

    from PowerQuee Media Posted on

    These couplers are AWESOME! I love having these around to put into my bigger bags for my bigger tips when I decorate my cupcakes. I have been looking for these and am so glad that I finally found them! Highly recommend!

    from Small and Simple confections Posted on

    Great coupler, as expected of anything Ateco brand! It's made of thick, sturdy plastic and holds the tip firmly in place. The product description notes the tip sizes that work with this coupler; standard and large couplers are also available on webstaurant at excellent prices to accommodate other tip sizes.

    Posted on

    Perfect size for the tips that I ordered on here made by a no name company. I just wish I had known that those tips needed a medium sized coupler. They work great.

    from A Bite on the Side Posted on

    My set of tips has a few larger ones that don't fit a standard coupler . They though fit this one perfectly. I also have some Russian tip spheres that are too small for the large one used with Russian tips but too large for the standard coupler. They too fit this medium one. I will be buying more. They are sturdy and clean well.

    Posted on

    A Large sized and hard to loose handy item! The grooves have head up to daily use and this coupler does work great with the right tips,

    Posted on

    Yes! Another great product from Ateco! I have several of the smaller couplers and use them all the time. I decided to give this a try because I use the Wilton 1M tip quite often. This was a perfect fit for that tip and a few others in that same size. As usual, you can't beat Webstaurant's prices either!

    from Baked Bliss by Laura Posted on

    This is great, whether you're using one tip or swapping. It keeps the tip securely in place - no popping through a stretched or torn piping bag. I changed tips multiple times with very little effort. Very worth the minimal investment.

    Great size! Ateco 402 3-Piece Medium Plastic Coupler (August Thomsen) Are great couplers! Who wouldn't want to get one of these products! You will enjoy it!

    from Tightline Connection Posted on

    These fits perfectly with my tips. They're easy to use without rocket science!! I like simple and hassle free products and this one is just that, hassle-free!!!

    from Tina's recipes Posted on

    This is a excellent adaptor but i can't seem to get the end to screw over my cancas bag. I do not want disposable bags or the plastic lined fabric ones either so i guess all this will just be in my storage room.

    This medium coupler works nicely. Holds our tip firmly in place and lets us change them out as needed. Great price for the Ateco 402-3.

    from Russ' Sub Shack Posted on

    Good coupler for higher volume applications, an absolute necessity if piping is a significant part of your business. We have plenty of these sitting around.

    from Mike's Mindful Plate Posted on

    These couplers work great for the most part! I have found when mixing it with Wilton products, they sometime leak. So try to keep the Ateco sets together.

    from Sweet Treats Bakery Posted on

    This coupler set is a must if you want to use your pastry bag with different tips without getting your hands dirty. You can use the medium and small tips with this couplers. I also have the large coupler of Ateco to use with the larger tips, and I'm very happy with them. Recommended!

    Ateco 402 3-Piece Medium Coupler Set (August Thomsen) fits the larger tips perfectly. You can never have enough of these around. They price allows that!

    Ateco 402 3-Piece Medium Plastic Coupler (August Thomsen)

    I bought this item on a whim because I normally don't bother with a coupler when using the larger tips. It is as expected, a good quality coupler by Ateco.

    Posted on

    This coupler is offered at a great price and gives you flexability and convenience while decorating. Be sure you are ordering the right size coupler as these items are not one size fits all pastry tips!

    Posted on

    This medium coupler works well for some of my larger tips and bags. It is designed well and cleans up easily. A standard for any baker.

    Posted on

    Great coupler and the price cannot be beat. Even though they are plastic they hold up pretty well. It is good to have a ton around while you are decorating with multiple colors.

    Posted on

    I'm a beginner and trying to figure this all out. I think I got a good one because it was easy to install, fits well, and didn't leak, also easy to clean, what more can I ask for?

    When you want to have a variety of sizes in being able to decorate your cake, this is the product you want to buy. Works so well in making sure my cakes look different and beautiful

    from Jr's Catering Solutions Posted on

    This medium size coupler is what I use with almost all my pastry tips. I haven't experienced any leaks and is super easy to clean. It comes in 3 pieces- a coupler and 2 rings to accommodate a range of tip sizes. Before I got into baking I had no idea what a coupler was, but now I know it's a definite necessity since it allows you to change a pastry tip without having to change a whole pastry bag.

    Posted on

    A great purchase. I use them all the time. Super easy to switch different tips without having to use a new pastry bag for different style tips.

    Posted on

    well designed. very functional. easy cleanup. good grip for working the frosting on anything from full size cake to smaller cupcakes. very pleased with the item and would recommend to others. sturdy design and easy to assemble

    from Chad Fenner Posted on

    Awesome coupler, comes with an extra top just in case you lose the first one! Fits well with most of my tips! We recommend ateco to everyone!

    from CakeBox Posted on

    I needed a larger coupler and this one does the trick. This product was what I expected. They work like they are supposed too. Great price good product.

    Posted on

    This will work very well if the tip fits the coupler, but some of my smaller tip won't stay in it... But for the one thst fit it work very well!

    Posted on

    Couplers are a must have when frosting lots of things and working with tons of colors. I don't know how I would manage without these couplers!

    Posted on

    I'm glad I purchased this size and that it comes with two different coupler "lids". One is more open than the other one. The one that has a smaller opening fits well with my cupcake swirl tips. I use the Wilton 1B tip for my cupcake swirls.

    Posted on

    I really don't understand the reason for the 3rd piece of this 3 piece set but I use the two pieces just fine and use the 3rd as backup..

    Posted on

    This is a huge coupler works great with my large bags when I have to do a large quantity of cupcakes, cookies or cakes . Very cheap too!

    from stellas custom cakes Posted on

    They hold tightly which is very important. I had bought a set from a local store a few years back and put up with them not staying in place for too long before replacing them with these. Always a happy shopper here.

    Posted on

    These are a must have for anyone that is decorating cakes, When you have a big bag of Butter cream and you need to change to different tips this makes that change a breeze!

    Posted on

    I think I will stick to using my standard and large coupler as I cannot get the medium coupler to fit snuggly in a disposable pastry bag. Maybe it would work better with a regular pastry bag. Does anyone have any suggestions?

    Posted on

    Thank you for your review! We are sorry the coupler set did not suit. Our experts recommend putting the coupler in the disposable pastry bag tip and measuring before cutting to ensure that the opening is the proper size for the coupler. This should help to fix the issue for you!

    this medium coupler set has 2 different sizes but the one size fits the wilton large tips perfectly eg 2D and 1M. so nice to change tips without emptying all the icing out of the bag to get the tips out of the bottom!

    Posted on

    I need these, they make changing pastry tips so much easier and keeps the tip straight when filling the bag with icing or filling- really great!

    from Confections by Kristin Posted on

    Same Ateco quality at a great low Webstaurant Store price. The Medium Sized Coupler "set" comes with two medium sized top pieces, to fit different sized tips. This is my most used size.

    Posted on

    Excellent pricing for a must have item that seems to disappears far too often. Makes changing decorator tips a breeze and we can keep plenty on hand

    from miss debs Posted on

    This should be in every cake decorator's arsenal. If you're into decorating, having a coupler makes the job smoother as you don't need to change out the entire bag to switch tips. Simply insert the coupler in the bag, add your buttercream and attach your decorating tip. When you want a new design, switch to a new tip. Simple.

    Posted on

    Great coupler set and also inexpensive. I love the ateco products as they are very efficient for my new and growing business. Can't wait to try out some of their other products!

    Posted on

    The medium coupler set is nice to have on hand for the in between tip sizes that don't quite fit on the standard coupler. Would recommend.

    Posted on

    Just what I needed! I was looking for this size locally, but it was difficult. At this price, I had to buy it here. Haven't been disappointed yet.

    Posted on

    ateco medium couple set allows us to use all kinds of big tips like big star tip or big rose petal tip etc.. without consuming time for changing bags. it gives 2 different caps for different size of couplers... i love to use them while decorating cupcakes..

    Posted on

    Great for having to change tips on a piping bag often. Especially helpful for decorating cakes and other piping needs. Have held up to constant use and haven't had any problems with them what so ever.

    from One Dish Cuisine Posted on

    I could not live without these medium couplers!! They work great! I own 4 sets! & If I need more, I know where to find them!

    from Heart of Cupcakes Posted on

    Ateco 402 3-Piece Medium Coupler Set (August Thomsen). This set is necessary to quickly change out medium sized pastry tips. The material is durable enough but be careful not to over tighten or you can split the nut.

    Posted on

    Ateco 402 3-Piece Medium Coupler Set (August Thomsen) is a very nice set. and fits in alot of size bags. This set is very well priced.

    Posted on

    Once again, great product from Ateco. I use only Ateco for my decorating and have not been let down. They work great, hold the bags and tips in place and are a quality product.

    from Me Too! Posted on

    You can never have too many of these. I have dozens, and they come in handy when switching from one decorating tip to another. Very durable and easy to use and clean. A necessity for cake or cookie decorating.

    Posted on

    These are plastic, fit together nicely, and run through the dishwasher fine - although they clean up very nicely with just a quick wash out at the sink, too. It's so nice to be able to have a secure fitting on the end of my piping bags, and it sure makes it a LOT easier to fill eclairs, and pipe out thicker ingredients, but do be sure you know the right size for the right couplers, before you buy. It can be quite confusing. Now I have all 3 sizes, but they're cheap, and should last forever, so I'm happy. : )

    Posted on

    Works well if the tip fits the coupler. Some of my medium tips slide right out. Easy to change tips and clean up is easy.

    Posted on

    I love the couplers and the price is pretty reasonable. The closest thing to me is a michaels store which wants at least an extra 25 cents more than on here.

    Posted on

    This medium coupler is great with the two different collars all the tips fit snugly. They are a great value would buy multiples for this price.

    Posted on

    Thanks so much for having great products like these for so cheap I love it. You can;t find deals like this anywhere, These do not leak!!! they are perfect!

    Posted on

    This coupler set is great for making it much easier to work cleaner when frosting and decorating cakes and cupcakes!!! Easy to switch tips on same bag!!

    Have been using these couplers for a couple months now on a daily basis and they are holding up really well. Ateco is a good brand for tips and couplers and we would buy again!

    from Cupcakes Like It Sweet Posted on

    This coupler set works well. It is worth a try and worth every scent buy a few extra because you know you may lose a few.
