New in package Ateco 404 large coupler set of 2

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!
