Ateco 400 Details

This Ateco 400 2-piece standard plastic coupler allows you to interchange small / standard-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 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. In addition, ridged edges on the ring allow you to easily assemble the coupler to the base with minimal effort. This coupler works best with standard-sized piping tips that have a 11/16" bottom diameter. 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!

In providing easy interchangeability for decorating tips, these couplers save a decent amount of time and equipment usage and free up workspace as well. They pair perfectly with Ateco's Plastic Coated Pastry Bags - a small investment with a huge payoff!

These are great for the price! In a bakery they tend to get lost. We use these everyday and we never have an issue with them. We will be ordering more.

Jodi A. from Iced on 03/03/2022

These plastic icing couplers are so nice to use. The ability to change pastry tips with out having to use multiple bags is very convenient.

Cte from Niles Comm Schools on 02/25/2022

Couplers are awesome!! This is the next greatest thing since slice bread, talk about VARIETY! From one piping to the next, but not changing the icing or the piping bag… that more could you want!

Jesse B. from Crossings Ministries on 02/25/2022

We have a billion of these things. Always a great price and works well with any standard tips. We usually soak them after use and they clean up easily with or without running them through a dishwasher.

Beau R. from Heroncrest on 02/09/2022

These work well! We started frosting our own froy cakes and these are great!. We never have any problems when my employees use there. Will buy more

Bernice B. on 01/08/2022

Belize F. from Southernbel on 10/24/2021

I am glad I can order these in bulk! They are a sturdy product. I ordered 6 to start and they came exactly as described.

Lacy P. from Delilahs Villains on 05/12/2021

These work great and have not had any issues with them. I suggest keep them in a separate container and washing yourself if you are dealing with a busy kitchen so that you don't lose any pieces at dish.

Suzana S. from Sweet Ludres LLC on 04/27/2021

Purchased along with the Ateco 21 Open Star Piping Tip. Fits perfectly with that tip and worked well with the plastic pastry bags we used.

Stephanie L. from Give Garden LLC on 02/15/2021

These couplers are ideal for dessert and cake decorating. Allows for using endless type of piping tips and only one bag. I have a bunch of these and wouldn’t decorate without them. Saves a lot of time and are very durable. Would deff recommend.

Carrie M. on 02/05/2021

These couplers are great. We use them for a birthday party that needed lots of cupcakes supplies. No issues with them whatsoever and they are obviously a great value

Casey B. on 01/04/2021

I used for many year, the material is strong, easy to put and out, easy to clean. When i put in the bag never broken the pastry bag.

Abdamina D. on 12/14/2020

These couplers are great! They screw in together perfectly. The plastic is thick and stain-resistant. They work awesome with my piping tips I have purchased here as well.

Mekka M. from A Piece Of Cake on 11/30/2020

WebstaurantStore is great for mechanical parts that you might need when a machine in the kitchen goes down. Fast shipment. Gets you back running in no time.

Sydney N. on 11/27/2020

This coupler is a must for all cake decorators. It is helpful if you want to change tips while using the same color. In addition it is so inexpensive!

Brocha N. on 11/10/2020

Apparent with these Ateco standard-size 2-piece couplers, quality is unrivaled. The grooves on the thread of the couplers are smooth with perfectly aligned. They easily twist together and apart. There are no problems experienced with attaching piping tips and bags for use. This product represents quality we can depend on and though small, is exemplary of an exceptional product.

Diep L. on 11/07/2020

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.
