Problem Solvers P-Nut Tubeless Kit

Standard valve nuts are often small and difficult to grip, especially when you need to tighten them by hand. The Super P-Nut features an oversized, knurled profile that gives you significantly more leverage, making it much easier to achieve a secure, airtight seal without needing pliers.

While they work on most rims, they are specifically engineered to excel with single-wall rim configurations. The concave design allows the nut to seat flush against the rim bed, which is a common pain point where standard, flat-bottomed nuts often fail to create a proper seal.

Yes, these are designed to fit standard Presta valve stems. As long as your valve stem is compatible with the 35mm length provided in the kit, you can swap out your existing nuts for these.

No tools are required. The oversized, CNC-machined design is intended for tool-free installation, allowing you to tighten them firmly by hand to get the necessary tension against the rim.

Yes, the valves included in this kit feature removable cores. This is a helpful feature if you need to inject sealant directly through the valve or if you need to replace a clogged core down the road.
