The SPGA bidirectional piston seal is a premium hydraulic sealing element specially engineered for piston sealing in hydraulic cylinders. Featuring a composite structure, this SPGA seal delivers reliable sealing performance in both pressure directions, making it ideal for double-acting hydraulic cylinders.
Manufactured from high-grade reinforced PTFE combined with an elastic O-ring energizer, the SPGA bidirectional piston seal offers low friction, excellent wear resistance and outstanding dimensional stability. It effectively prevents hydraulic fluid leakage while minimizing friction loss during reciprocating movements. The energizer provides consistent preload to maintain tight contact under fluctuating working pressure, adapting to heavy-load and continuous-cycle working conditions.
This SPGA piston seal works across a wide temperature and pressure range, compatible with most hydraulic oils. It resists extrusion and abrasion even under high pressure and dynamic reciprocation. Widely applied in construction machinery, agricultural equipment, injection molding machines and general industrial hydraulic cylinders.
With simple installation and long service life, the SPGA bidirectional piston seal reduces downtime and maintenance costs. It is a cost-effective sealing solution for demanding hydraulic piston sealing applications.
