This Ateco 231 large Bismark pastry tube is perfect for filling pastries with frosting or cream. Made of stainless steel, this tube is durable enough to withstand repeated use. Its larger size makes it ideal for filling pastries and confectionary creations quickly and efficiently. The perfect way to fill jelly donuts, cream puffs, and eclairs, this pastry tube is specifically designed with a longer tube to inject pastries with sweet butter cream, chocolate, mousse, and more! The extended tube allows you to fill each dessert with minimal disturbance to the outside of your product to keep its shape intact. It is also compatible with the Ateco 402 coupler and Ateco 407 coupler using the 7/8″ coupler ring, making it easy to switch tips without changing the pastry bag. Using the right sized pastry tube for the job will enhance your presentation to draw patrons’ attention to your display cases and plated desserts.
