Engine Seals

Modern engine seals are required to run at consistently high levels of RPM and power output consequently causing malfunction of many types of standard oil seals.
Our range of PLS Seals are designed to minimise friction losses while giving reliable seal function and are suitable for Wet Sump or Dry Sump running.
At the highest levels of vacuum in race engines our Duplex Seals provide the most reliable control of crankcase vacuum at all RPM while running with much lower friction than most other seals.
