GSC P-D Honda B/K/H Series Viton 5.5mm Valve Stem Seal - Set of 500

If you're rebuilding the top end of your Honda B, K, or H-series engine, replacing the valve stem seals is a critical step. These seals keep oil from leaking down the valve guides into the combustion chamber, preventing blue smoke on startup and oil consumption. GSC Power Division's Viton seals are a well-built choice for these popular Honda engines, offering a durable solution for keeping your engine running cleanly.

This set includes 500 seals, which is more than enough for most B, K, and H-series engines, even if you need extras for a performance build or a shop full of projects. Viton is a high-performance material known for its excellent resistance to heat and oil, making it a solid choice for the demanding environment inside an engine cylinder head. The 5.5mm stem size is specific to many Honda applications, ensuring a proper fit when you're installing them onto your valves.
