How do piston seals work?


Piston seals create a sealing contact between a piston and a cylinder bore in a hydraulic system. They stop fluid or gas from leaking and maintain the internal pressure needed to move the piston.

Will this product tolerate condensation in the environment?


Yes, the seal kit will cope well in normal industrial settings where condensation is likely.
