Glyd Ring Seal PTFE

Glyd Ring Seal PTFE

You can rest assured to choose Ruichen Seal as the manufacturer and supplier of Glyd Ring Seal PTFE. This product uses a combination of filled PTFE sealing ring and rectangular rubber ring. It is suitable for bidirectional pressure sealing of hydraulic reciprocating motion. It has extremely low friction, high pressure stability and ultra-long life. It is suitable for heavy-load, oil-free lubrication and water medium and other harsh industrial environments.
Reciprocating Piston Step Seal

Reciprocating Piston Step Seal

Ruichen Seals is a supplier of Reciprocating Piston Step Seals. Their piston (bore) stepped combination seals are used for high-pressure, one-way sealing in hydraulic cylinders, construction machinery, and heavy equipment. By providing continuous compensating force through the O-ring, this step seal maintains low friction and zero leakage under high-pressure, high-frequency reciprocating motion, making it particularly suitable for long-term, stable sealing in mining machinery, injection molding machines, and harsh industrial environments.
Glyd Ring Seal

Glyd Ring Seal

Ruichen Seals' square combination seals for pistons (bore) are designed for bidirectional pressure sealing in reciprocating hydraulic motion. The Glyd Ring Seal uses O-rings to continuously provide radial force and automatically compensate for wear, ensuring long-lasting and stable sealing performance. It features low friction, high pressure resistance, and excellent dynamic response. Used in conjunction with a guide ring, it is an ideal sealing solution for heavy-duty hydraulic cylinders and precision equipment.
Wiper Seal GP6

Wiper Seal GP6

As a leading manufacturer and supplier of piston rod seals in China, Ruichen Seals' GP6 dust ring is designed specifically for large-diameter piston rods. Made of nitrile rubber (NBR) (fluororubber (FKM) is optional for high-temperature conditions), it effectively blocks the intrusion of pollutants, has excellent wear resistance and environmental adaptability, and significantly improves the reliability and service life of hydraulic system seals.
