MPSA Piston Seal

A robust assembly designed specifically for one piece pistons, the MPSA double acting seal uses a rubber sealing element that has proved itself in service to be extremely wear resistant and capable of working most effectively in a wide range of medium duty applications. The seal is also suitable for two piece pistons.

The assembly comprises a rubber sealing element, two spit support rings and two split L-shaped bearings, one of each located either side of the seal.
