VALVE Series Industrial Mechanical Seals

ASA valve stem seals provide a defined metering rate of oil to the valve stem interface of internal combustion engines to lubricate the valve guide and minimize engine emissions. They are available for diesel and gasoline engines with and without boosting.

In addition to conventional valve stem seals, our offer also includes valve stem seals for engines with high pressures in the manifolds, such as turbochargers or for exhaust brakes on commercial engines. Featuring a low friction design, these seals improve the quality of emissions and enhance engine operation by withstanding high pressures in the exhaust and intake ports of the engine.
