Muc-Off Valve Core

These cores are designed for standard removable Presta valve stems. They will work with most tubeless valves that feature a removable core, but they are not compatible with non-removable or fixed-core valve stems.

Valve cores often become clogged with dried tubeless sealant, bent, or damaged over time, leading to air leaks or difficulty inflating your tires. Replacing the core is a quick, inexpensive way to restore a perfect seal without replacing the entire valve stem.

No special tools are strictly required, though a standard valve core removal tool makes the process much faster and easier. You can generally install or remove them using a small pair of pliers or a dedicated core tool.

Each pack contains 10 replacement valve cores. This is a convenient quantity to keep in your toolbox or gear bag so you always have spares on hand for yourself or your riding group.

Yes. They are machined from 7075 aluminum, which is highly durable and resistant to the elements. They are specifically engineered to maintain an airtight seal even when exposed to mud, grit, and rain.
