Muc-Off Tubeless Valve

These are designed for standard tubeless valve systems. However, they specifically feature a large round grommet shape, so you should verify that your current valve base matches this profile before purchasing.

You should replace them if you notice sealant weeping around the valve stem, if the rubber appears cracked or deformed, or if you are struggling to maintain air pressure despite a properly seated tire.

This pack is primarily intended for workshop environments, bike shops, or riders who maintain a large fleet of bikes. It ensures you always have a fresh seal on hand without needing to buy entirely new valve stems.

Yes, provided the leak is caused by a worn or damaged grommet. If the leak is due to a bent valve stem or a damaged rim bed, replacing the grommet alone may not resolve the issue.

No special tools are required. You simply unscrew the valve nut, remove the old grommet from the valve stem, slide the new one on, and reinstall the valve through the rim hole.
