TBP2 Seals

Valve Stem Seals in modern race engines encounter operating conditions much more extreme than in previous generations. The higher speeds, higher temperatures, with chemical attack due to oil oxidation, all effect the reliability of the Stem Seals.Very little is understood of the effects from the combination of inlet boost pressures & crankcase evacuation which affect the stability & sealing function of many Stem Seals.PLS Seal technology applied to Valve Stem Seals provides the ideal solution being less sensitive to the pressure differentials while also reducing rubbing friction.The connsistency in oil film control with these PLS Seals is excellent over long periods of endurance testing.
