Piston Bore Seals

The SPGW Seal utilizes a combination of a filled PTFE sealing ring, a special elastomer, and double retaining rings. Designed for bidirectional pressure sealing in reciprocating hydraulic applications, it is one of a wide range of seals from Ruichen Seals. This product offers extremely low friction, high pressure stability, and multi-media compatibility (suitable for oil, water, and non-lubricated applications). It maintains zero leakage and a long lifespan even under high pressure, high speed, and harsh environments.

If you are looking for SPGO Seals for high-speed hydraulic and pneumatic applications, choose Ruichen Seals as your supplier. We use a combination of modified PTFE seals and O-rings. Our products offer excellent sealing, ultra-low friction, and a compact design, making them particularly suitable for high-speed hydraulic and pneumatic cylinders.
