Icing Coupler - what is it and how to use it

Have you heard of icing coupler before? Well, I have definitely mentioned in quite a number of pages on my site and it a tool that it closely associated with piped cake decorating techniques. Having said that, you do not need a coupler for all piped decorations, some can also be done without a coupler , and it all depends on the piping tip you are using. So first things first. This is what a coupler looks like:

Its made of plastic and has 2 components. One long cylinder shaped piece and another one that looks like a nut. These are mostly made in plastic and come is many different colors. The ones I use are Wilton couplers and the size can fit all Wilton standard piping tips (by standard I mean the normal sized piping tips and not the larger ones like tip number 2D.) There are off course larger couplers for the larger piping tips but I find that the larger tips don't really need couplers and work fine on their own. Using this coupler is so easy that it is often assumed one would know how to use it without any demo. And that was what I thought too all this while until someone asked me what a coupler is and how to use to. So I decided to do this small write up on icing couplers.

What is an icing coupler used for?

Icing couplers are basically used for all kinds of piped decorations that use piping tips. It is used primarily to secure the fit of piping tips to piping bags so that the icing does not leak out when squeezed for piping. And also makes changing icing tips easy as the tip is held by the coupler outside the piping bag.

How to use an icing coupler?

Ok this is the fun part - the demo. I'll show you how to fit a coupler into a piping bag and how to secure a piping tip with it in the best way to avoid icing leaks. These are the supplies you would typically need:
  • Piping bag (I am using a disposal piping bag here)

  • And this is how to fit the coupler to your piping bag. Start by dropping your cylinder component into your piping bag and push it right to the tip.

  • Next, using a marker pen, draw a small line as a cutting guide. The position of the line is very important to avoid leaks in the piping bag so always make sure its no more than the one third mark from the bottom of the coupler and is always below the thread lines on the coupler. 

  • And then, push the coupler up so that you can cut your piping bag along the line marked earlier. 

  • Once cut, push the coupler back to the tip of the piping bag. This is how it would look like.

  • Next step is to fit the piping tip. That will be done using the coupler nut. 

  • Place the nut as shown below:

  • And then, simply lift the tip with the nut on and screw it to the coupler in the piping bag like this:

  • This is how it should look like when done.
  • You can then fill the bag with icing and start decorating your cake. And if you need to change the tip, simply unscrew the nut and replace the piping tip before screwing it back again. 

And that is how you use a coupler for cake decorating piping. Here is a short video I've made, showing you how to fit a coupler into piping bag. 

Hope you enjoyed this tutorial. 

Happy decorating :)
