Set of 4 CENTAURO valve stem seals designed for engine reconditioning. These seals, intended for intake and exhaust, are suitable for maintenance operations where the sealing of the valves needs to be restored. Their design meets the thermal requirements encountered under the cylinder head, particularly on demanding 4-stroke engines.
Fitted as original equipment by several manufacturers, these seals integrate easily during a cylinder head revision or a targeted replacement of guides and valves. They are particularly suitable for the Cross and Roadster environments and are compatible with 350 cc single-cylinder 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 the proper functioning of the engine.
