Installed as original equipment by several manufacturers, these seals integrate easily during a cylinder head revision or targeted replacement of guides and valves. They are particularly suitable for the Cross and Roadster environments, and are well-suited for single-cylinder 350 cm3 engines such as the HUSQVARNA FC 350 (2025), KTM 350 XC‑F (2024), or GAS GAS MC 350 F (2024). Compact and specifically sized for the valve stem, they help limit oil loss into the combustion chamber and maintain proper engine function.
