PPA PU Double Acting Piston Seal is a barrel-shaped sealing element designed for use in pneumatic cylinders and valves. Its compact profile requires a small installation groove while providing reliable sealing performance, making it suitable for space-constrained pneumatic applications.
With a compact cross-section and smooth sealing lip geometry, PPA helps minimize both dynamic and static friction for smooth and stable piston movement. The pneumatic piston seal is suitable for applications using dry air as well as oil-free compressed air. The smoothly transitioned sealing lips help reduce wear during reciprocating movement, contributing to reliable sealing performance and a longer service life.
