Piston Seal P31
DESCRIPTION
Single-acting Piston Seal for standardised housings according to ISO5597 has asymmetrical profile and shortened outer lip, high extrusion resistance thanks to integrated back-up ring and pressure-relieving grooves.
Piston Seal P31 can be installed in “back-to-back” position in double-acting piston design with pressure on both sides.
