This coupler is designed for use with large decorating tips and includes one coupler screw base and two screw on coupler caps. This large coupler is compatible with large decorating tips and is designed to be used with 14” and larger pastry/decorating bags.
Couplers make it easy to change pastry/decorating tips on the same icing bag. This saves you time and energy because you can pipe as many different designs as you have tips, without having to set up a whole new pastry bag for each tip you want to use.
Simply slip the largest piece of the coupler into the pastry bag so that the small end of the coupler opening is pointing down into the opening of the pastry bag. Next select the tip that you want to use and place it over the coupler on the outside of the pastry bag. Next screw on the coupler cap over the outside of the pastry bag and over the decorating tip so that it holds the tip in place. Fill your pastry bag with frosting and you are ready to decorate! When you want to change tips just unscrew the coupler cap to remove the tip you are using, place on a new tip and screw the coupler cap back on.
