GODA-SPE PISTON SEAL
The slide and O-Ring seal type GODA-SPE is a single acting seal with pressure releasing profile to one side. The pressure discharge reduces the friction in pressurized condition and allows the seal to react more sensitive to pressure changes.
The seal additionally has the ability to convey leakage oil which may arise from the seal gap back into the system.
