How Does Muc-Off MTB Tubeless Sealant Seal Punctures?

Muc-Off MTB Tubeless Tire Sealant uses Fibre-Tek Particles suspended in a latex base to seal punctures of up to 6mm the moment air pressure drives the formula into the hole. The particles mat together at the puncture site for fast closure on trail-sized holes, rather than relying on liquid alone to seal under pressure.

The 140ml pouch is pre-measured for a single MTB tire fill, making it easy to add the right amount without measuring cups or spills on the trail. Store one or two in your pack or hydration vest for on-trail top-ups, or use it as part of a full tubeless conversion alongside compatible rim tape and valves. Compatible with 27.5, 29, and plus-size MTB tire diameters.

FAQ

How do I inject the sealant from the pouch?

Remove the valve core using a valve core tool, attach a sealant injector to the valve, cut the corner of the pouch, and inject directly into the tire. Replace the valve core, inflate, and rotate the wheel to distribute.

How often should I top up tubeless sealant?

Most riders top up every 2 to 3 months depending on climate and riding frequency. Hot, dry conditions cause sealant to dry out faster. Check sealant level periodically by removing the valve core and inspecting inside.

Is 140ml enough for a full MTB tire conversion?

Yes. A single 140ml pouch is the right volume for one MTB tire fill at Muc-Off recommended levels. For a full wheelset conversion, you will need two pouches.

Best For

MTB riders who run tubeless and want a trail-packable single-serve sealant pouch for on-the-go top-ups or single tire conversions.
