How-Tos: Using a coupler (with step-by-step instructions)

If you are just starting out with cake or cookie decorating and are new to piping, here's a useful step-by-step tutorial on how to use a coupler.

Using a coupler is very useful, especially when you want to use the same icing with different piping tips. Or if you are simply fickle, like me. I tend to have the impromptu want to switch piping tips, so using a coupler is almost always a must for me.

Step 1: Unscrew your coupler

Step 2: Insert the coupler into the piping bag and push it to the end, until you can't push any further. Make a mark at the point in the picture above. That's where you will cut it. 

Step 3: Loosen the coupler a little from the end of the piping bag and cut at the line where you marked it before. Then push the coupler to the end of the piping bag (make sure it is tight and does not wriggle around!), like how it looks in the above picture.

Step 4: Take the piping tip you want to use and hold it in place over the coupler.

Step 5: Attach the screw over the coupler tightly such that the tip does not move around.

Step 6: Done!

As and when you want to change the tip in between whatever you are doing, just unscrew, take out the tip, attach the new tip you want to use and screw it back tightly to the coupler. Easy peasy! :)

    1. Hi Chloe,
      During my first time, I was also clueless and I used it the wrong way. I thought some instructions might help someone one day and I'm so glad it helped you! :)
