To lubricate the valve guide and reduce engine emissions, valve stem seals deliver a precise metering rate of oil to the valve stem contact of internal combustion engines. They are for gasoline and diesel engines, both with and without boosting.
Along with standard valve stem seals, we also offer valve stem seals for engines with high manifold pressures, such as those with turbochargers or exhaust brakes on commercial engines. These seals, which have a low friction design, can resist high pressures in the engine's exhaust and intake ports, enhancing engine performance and improving emissions quality.
