Problem Solvers Big P-Nut Tubeless Valve Kit

The oversized nut provides significantly more surface area and leverage than standard, smaller nuts. This allows you to tighten the valve base by hand more effectively, ensuring a secure, airtight seal against the rim without needing pliers.

These valves are designed to work with most standard tubeless-ready rims that accept Presta valves. However, because the nut is oversized, you should ensure your rim's valve hole area has enough clearance to accommodate the larger diameter nut.

Yes, the removable valve core design is compatible with most tire inserts. The removable core allows for easy sealant injection and ensures that airflow is not restricted when using inserts that require specific valve clearance.

These valves have a 35mm stem length. This is a standard length suitable for most alloy and shallow-to-mid-depth carbon rims, but you should measure your rim depth to ensure the valve will protrude enough to attach your pump head.

No special tools are required. The oversized nut is designed to be tightened by hand, and the kit includes a removable core, which can be serviced with a standard valve core tool or a pair of needle-nose pliers.
