Ruichen Sealing is a professional manufacturer of cap combination seals. This product is an ideal choice for bidirectional reciprocating sealing in hydraulic and pneumatic equipment, featuring an assembly of a PTFE cap seal and a rubber O-ring. It relies on the O-ring to provide continuous radial pressure and automatically compensate for seal wear; combined with an optimized thin-lip design, it offers excellent responsiveness and sealing performance, and is directly compatible with standard GB1235 O-ring grooves.

Equipment manufacturers purchasing high-pressure reciprocating piston rod seals can choose Ruichen Seals' patented Y-type Combined Seal (patent number XL200420025796.8). This axial hydraulic combined seal is assembled from a filled PTFE Y-type slip ring and a rubber O-ring, specifically developed for hydraulic unidirectional reciprocating seals. Its unique patented configuration, combined with optimized thickness design, solves the sealing problem of low-viscosity water media, effectively improving ultra-high pressure carrying capacity.

Looking for a reciprocating shaft seal solution suitable for ultra-high pressure and water environments? Choose the RC08/RC09 Reinforced Right-Angle Combined Seal, developed and manufactured by the professional manufacturer Ruichen Seals. It consists of a PTFE-filled reinforced right-angle sealing ring and a GB1235 series O-ring. The sealing ring thickness is optimized for low-viscosity media, and the reinforced structure increases the pressure limit. The product boasts excellent frictional characteristics, smooth operation without creep, and achieves long-lasting oil-free lubrication.
Purchase Selection Note: This seal is not suitable for enclosed groove installation.

Ruichen Seals' RC06 and RC07 series C-type Combined Seals utilize a PTFE composite C-ring + GB1235 O-ring combination structure, suitable for hydraulic and pneumatic reciprocating bidirectional sealing. The thin-lip design provides excellent following compensation capability, ensuring smooth, creep-free operation with low friction. It caters to both high and low pressure sealing needs, supports oil-free lubrication, and boasts an excellent service life. Available globally, bulk orders are welcome.
