When a puncture in your tubeless tyre is simply too big to seal, the Muc-Off Puncture Plug Repair Kit is the ultimate backup tool that’s lightweight and easy-to-use.

Inside the kit, you'll find a tough stainless-steel tool that doubles up as both a reamer and a plug, with a durable handle on the top that makes it compact and lightweight. You'll also get two different sizes of puncture plugs, which will seal multiple holes and cover you for a variety of different sized punctures.

To keep everything nice and secure, the kit comes complete with a tough Cordura pouch. As the tool is sharp, it has a rubber fitment on the top for safety, and if you keep it inside the pouch, and inside a saddle bag, you'll be well covered.


How do you use them?

We have this video which will show you all the steps:

Or if you'd rather read how to do it, check out our step by step guide below:


  • Step 1: To start, you'll need to remove the source of the puncture. Just be careful when you're doing this in case there is anything sharp inside the tyre. For a larger hole, you're only initially going to need to use the reamer section of the tool.
  • Step 2: Insert the tool down into the tyre up to the reamer section, and then move it backwards and forwards just to roughen up the edges. This is going to allow the plug to create a better seal when you go ahead and put it into the tyre.

  • Step 3: Once you've gone ahead and roughed up the inside of that hole, all you need to do is take one of the larger puncture plugs, pinch the end down, thread it into the very end of the tool, and pull it all the way through until it's about halfway in. Simply aim at the hole, press down until the puncture plug is around halfway in.

  • Step 4: To remove the tool from the tyre, simply twist it a few revolutions whilst holding the sides of the plug down and then pull it slowly out. If you happen to be carrying something that allows you to trim the excess off, you can go ahead and do so. If you don't, you can just do this when you get home. When you're trimming the excess off, just be wary of the tire so you don't take too much off.
  • Step 5: With the hole in the tyre now plugged, you'll need to reinflate it – we recommend using one of our CO2 canisters. Once you've done this, give the wheel a few rotations to get the sealant flowing, and then the wheel is good to go back on your bike.
