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!

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.

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!

I recently used the Ateco 404 2-Piece Large Plastic Coupler with my Wilton 191007384 Purple Rubber Pastry Bag Ties and was impressed with its functionality for cake decorating. Made from high-density polyethylene (HDPE), this coupler allows easy swapping of large-sized piping tips (9/16", 5/8", 11/16", and over 3/4" bottom diameter) without emptying the pastry bag, saving time and reducing mess.

This is an easy to use coupler. It fits all of my standard size piping tips. I like these couplers because they have yet to be stained by food coloring. I use them with my cloth and plastic piping bags. I recommend this product if you are looking for easy to use couplers..

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 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.

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!

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.

Love these couplers for my medium size tips. It makes it much easier with a coupler so that you can use multiple tips with one pastry bag. It’s hard to find this specific size of coupler.
