Piston Seal Set P10
DESCRIPTION
Piston Seal Set P10 is a compact two-piece piston seal. It consists of one fabric-reinforced rubber sealing ring and two guide rings for guiding through the cylinder.
This is an economical sealing and guiding solution with excellent sealing effect, good dynamic and static friction behavior and good abrasion resistance.
