PROX Valve Stem Seal - Manufacturer Ref. 35.VS006
This PROX valve stem seal is specially designed to maintain a seal around the valve stem and limit the entry of oil into the combustion chamber. A replacement part intended for quad and motocross engines, it is essential during a cylinder head revision or routine maintenance on your cylinders.
Easily interchangeable in the workshop, this seal is mounted between the valve stem and the guide and helps regulate the flow of oil along the valve stem. Supplied individually, it is suitable for occasional interventions where only the seal needs to be replaced.
Workshop Tip: Check the condition of the valve guides and replace the seals in pairs if necessary to avoid recurring leaks. Use the appropriate tools for a clean installation without damaging the part.
