The PGY piston seal is a premium hydraulic sealing element specially designed for piston installation inside hydraulic cylinders. It serves to block cross-chamber hydraulic fluid leakage on both sides of the piston, ensuring stable pressure transmission during reciprocating movement.
Constructed from high-grade polyurethane with optimized profile design, the PGY piston seal features superior abrasion resistance, great tear strength and reliable anti-extrusion performance. Its geometric structure provides uniform contact pressure against the cylinder bore wall. It maintains consistent sealing effect under fluctuating hydraulic pressure and continuous cyclic operation, reducing friction loss and extending service life.
This PGY piston seal works within a wide temperature and pressure range and is compatible with most standard hydraulic oils. It can withstand heavy-duty working cycles and harsh operating environments, resisting extrusion damage and abrasive wear effectively.
It is widely used in construction machinery, agricultural equipment, hydraulic presses, injection molding machines and general industrial hydraulic cylinders. Easy to install and replace, the PGY piston seal helps reduce internal leakage and cut equipment maintenance costs.
