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!

Excellent coupler for the large ateco piping tips. Makes it easy to swap out tips on piping bags. They are easy to wash and disinfect.

These are made of high quality material that are durable and easy to clean. They fit with my JUMBO size tipping these are massive and are fun to decorate with - buy the tips to go along tho.

The ateco large coupler is perfect for all bakers. I would definitely recommend this product and I would definitely purchase again. It is such a great product.

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.

Christina C. from A Lil' Sumpin' Special on 02/17/2021

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.

Kelly G. from Kelly's Kitchen LLC on 01/22/2021

This plastic coupler is helpful if one needs to switch piping tips while using the same color. It is easy to use & good quality,

Misti S. from Buttercream Bakery on 11/08/2020

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.

Jordan P. on 11/02/2020

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.

Ivan M. from Ivan Munoz on 10/18/2020

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.

David H. on 08/21/2020

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

Angel T. on 06/28/2020

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!

Praparat S. from Thai Gourmet House on 05/28/2020

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.

Erin K. from  on 04/17/2020

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.

Kia P. from Palmer's on 04/14/2020

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.

Tom D. from Tom Dewar on 02/23/2020

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.

Jaime S. from Sweet Tooth Shop on 01/29/2020

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.

Gonzalez H. on 12/13/2019

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.

James B. on 10/28/2019

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!

Loan L. on 10/10/2019

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
