Muc-Off V2 Tubeless Valves

Yes, they are specifically engineered for that. The base of the stem features six machined slots that create an air flow system, ensuring your sealant and air can pass through freely even when a tire insert is pressed against the valve.

The correct length depends on the depth of your rim. You need a valve long enough to protrude through the rim hole with enough clearance to attach your pump head, so measure your rim depth and choose the 44mm, 60mm, or 80mm option accordingly.

These valves come with multiple rubber bases to ensure a secure, airtight fit across a wide variety of rim profiles. While they are designed for versatility, it is always a good idea to check your rim's internal shape to ensure the base seats properly.

The valve cap itself acts as a tool to remove the valve core. This is incredibly convenient for adding sealant directly through the valve stem or for replacing a clogged core without needing to carry an extra dedicated tool.

You can install them by hand, but the stem features a 4mm machined Allen key slot at the base. Using an Allen key allows you to tighten the valve securely to the rim without over-tightening or damaging the nut.

Yes, they are constructed from aircraft-grade 7075 aluminum. This material is significantly stronger and more durable than standard plastic or lower-grade alloy valves, making them well-suited for the rigors of mountain biking.
