Couplers are the easiest way to attach varying piping tips to the same bag of icing.

• To use, place the large portion of the coupler into your piping bag and cut the bag tip to meet the first visible thread of the coupler. Put a tip over the end of the coupler. Use the cap to secure all pieces together.
• When you are ready to change tips just unscrew the cap, place a different tip in place, then use the coupler outer ring to secure the tip to the bag and the inner coupler.
