Problem Solvers Super P-Nuts Tubeless Kit

Standard valves often struggle to seat properly on single-wall rims because the rim profile doesn't offer much surface area for the rubber base to grip. The Super P-Nuts feature a concave base that conforms to the rim's shape, creating a much more reliable, airtight seal where others fail.

The oversized nut provides significantly more surface area for your fingers or pliers to grip. This allows you to apply more torque when tightening the valve, ensuring it stays firmly in place without vibrating loose or leaking air during your ride.

Yes, these valves feature a removable core design. You can easily unscrew the valve core to inject sealant directly into the tire, which makes maintenance much cleaner and faster.

These valves have a 35mm stem length, which is ideal for standard single-wall rims. If you are running deep-section aero rims, these will likely be too short, so be sure to measure your rim depth before purchasing.

Brass is heavier than aluminum, but it is significantly more durable and less prone to stripping or bending under high torque. For a tubeless setup, the reliability of the brass construction is generally worth the negligible weight penalty.
