How to Use a Pastry Tip Coupler

How to Use a Pastry Tip Coupler

Taking your desserts from average to exemplary is as simple as knowing your way around a pastry bag. Various tips create exceptional designs, but to use those tips, you need to first know how to use a coupler. Begin by unscrewing the ring at the base of the coupler. Open your pastry bag, and drop the coupler inside, pushing the narrow end of the coupler into the narrowest part of the bag. Then, mark with your finger where the beginning of the screw thread lines up on the bag. Push the coupler up and cut the bag at the marked line. Push the coupler back down through this hole until the hole lines up with the beginning of the coupler's threaded lines. Place the decorating tip over the part of the coupler which is showing through the hole. Grab the ring and screw it back onto the coupler, securing the decorating tip in place. Simply unscrew this ring, remove this tip, and add a different tip if other designs are desired while decorating. Add frosting to your pastry bag and your signature desserts are ready to be decorated!

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!

    If you have decorated cakes for any amount of time, you know that couplers break. The rings that hold everything together, sometimes, inexplicably, go missing. It feels good to have extras on hand to replace, without having to run to the craft store.
    This coupler for pastry bags fits my tips (different manufacturer) very well. Having extra couplers allows for more flexibility in the kitchen for multiple frosting varieties or tips.
    This plastic coupler is helpful if one needs to switch piping tips while using the same color. It is easy to use & good quality,
    love these couplers. they make changing my tips very easy. they are well constructed and the threads on them are matched up every time. highly recommend
    How did we go so long without using one of these? We don't usually swap out piping bag tips, but the plastic coupler makes sure the tip is held nice and secure in the tip of the bag. It's a little extra cleaning in the end but definitely worth it.
    This Ateco coupler is works well with a different variety of tips. It is heavy duty and well priced. No problem using them with the Ateco Canvas Pastry Bags.
    Whoa this ateco 404 coupler is huge. it was too big for my tips so I gave it away to a friend and they are quite happy with it.
    very good product. good quality plastic. Also available in various sizes. Must buy if you work with multiple tips are the same time! Must buy
    These are massive and are fun to decorate with - buy the tips to go along with at the same time. It would be really helpful to have them together. Very sturdy and well worth the money for the price! Will definitely order it again if needed!
    This is a great extra big coupler for using with piping bags. I always use one of these when piping multiple styles of buttercream on cupcakes.
    These couplers save us on pastry bags. Easy to use. Easy to clean. I should have purchased more. Will definitely re-order a new round soon.
    This is a great device. It allows me to change tips while I am piping eclairs. I will make some with a round tip and then change to a star tip for variety. This saves me time and enhances my productivity.
    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
