Ateco 404 Details

This Ateco 404 2-piece large plastic coupler allows you to interchange large-sized piping tips with absolute ease! Even though all reusable bags can accept small decorating tips without a coupler, this convenient item enables you to swap out large-sized piping tips without having to empty the contents of your decorating bag, which saves you time and labor. That said, to use this coupler properly, simply trim your reusable bag before use! However, since canvas bags with a sewed seam cannot be trimmed, they are not compatible with this item.

Although this coupler works best with large-sized piping tips that have more than a 3/4" bottom diameter, this item can accommodate 9/16", 5/8", and 11/16" pastry tubes. In addition, ridged edges on the ring allow you to easily assemble the coupler to the base with minimal effort. Ideal for bakeries, cake decorators, coffee shops, and anywhere else you need to decorate baked goods, this plastic coupler will get the job done!

Bringing you innovation and quality for over 100 years, Ateco, an August Thomsen brand, has been internationally known in the industry for creating baking tools of superior craftsmanship and design. By continually improving on tools, materials, and packaging, Ateco is dedicated to providing professional bakers with the kitchen essentials they need to succeed in an ever-evolving industry!

    These large coupler work great with the large Ateco pipping tips. We use them everyday. They make our mornings of decorating cupcakes easy by being able to switch tips to use with the same frosting.
    Large coupler well made and strong. Easy to use. I ise it with my very large tips. It is easy to clean and to reuse.
    Love this size coupler to fit all of my larger tips including the Russian tips. They make such a quality product at such a reasonable price.
    FINALLY! I've been looking for a coupler to fit my russian piping tips for the longest bc they would always pop out of my piping bags without one! I'm so excited that I cam across this, especially with how cheap it is!
    We use these daily with the large circle tips. Perfect for icing large numbers of cupcakes. Fit nicely in the 22” and larger bags, too
    These couplers are really big but a must when using the modern extra large tips for special decorations. We use these quite a bit for our cakes.
    What can I say? They work well and do what they're supposed to. Now, if I could only get the staff to not loose them I would be happy. They are good quality and have been used many of times without any issues. I would buy these again.
    This Cupler is great to own makes it easy to pop off many different tips way faster to get the job done easy to use Cupler twist off insert your tip and screw the lid back on
    i must give a 5 star review to this Ateco 404 2-Piece Large Plastic Coupler because of its material is very resistant, white plastic the price does not match the quality !!
    Nice and large. Good quality even though it's plastic. Coupler fits together well, and fits the large piping tips perfectly. Would buy again. Great value. Good quality.
    These couplers are big, they're perfect for Russian piping tips since Russian tips are usually big. Using this coupler allow me to replace the tips without making a mess.
    The coupler is a must for piping. One piece on the inside of the bag, and the other works with the tip, screws together easily. It comes in small, medium and large to fit different tips. Excellent.
    Even large / jumbo piping tips can get clogged when I'm piping cupcake frosting so I love having a coupler that fits those tips like this one. Of course it's also great to have for times when you might want to use 2 different jumbo piping tips for different designs using the same frosting. Great product for a great price.
    I bought these for my Russian flower tips and it works great! It’s nice being able to quickly change my Russian tip. I couldnt find these anywhere else! So worth the money!
    I used these for my Girl Scout Troop. We were earning a baking patch. These worked great, and the girls really enjoyed the activity. They were able to bake and decorate their own cupcakes.
    LOVE this product. This makes frosting and decorating a breeze. Fit the bag with this coupler and you can change the tips out as many times as you want without having to fuss with a separate piping bag each time.
    This coupler is huge (about 2" tall) but in a great way! The perfect size for using large tips. I use it with my Ateco 809 round piping tip and Ateco 849 closed star piping tip when I want jumbo frosting on cakes and cupcakes.
    Don't assume these will fit what you need them for. Make sure you note the measurements and what tips they'll actually work for! I ordered them and can only use them on one size that I even own. They are comically big. They do work great, totally my fault for not seeing how big they actually are.
    I honestly don't know if I will need a coupler this size, but I was getting the standard and medium sizes so I decided to add this to my collection. Yet to try it out but am sure it will not disappoint when I do.
    These couplers are huge but very nice when decorating cupcakes. I love being able to change out tips instead of having to use multiple bags. The Ateco tips are very well made of sturdy plastic as well.
