Ateco 404 Large 2-Piece Plastic Coupler for Pastry Bags

The Ateco 404 is a 2-piece large plastic coupler engineered for professional cake decorators and bakery operations that rely on large-format piping tips. Designed to accommodate pastry tubes sized 9/16, 5/8, and 11/16, it is especially well-suited for large tips with a bottom diameter greater than 3/4 and is fully compatible with Russian nozzle tips. Its core advantage is the ability to swap out piping tips mid-task without emptying the decorating bag, saving valuable time and reducing waste. Ridged sides on the locking ring allow for fast, secure assembly and disassembly with minimal effort. Crafted from durable white plastic, this coupler delivers a reliable, leak-resistant fit ideal for bakeries, cafes, and professional pastry kitchens.
