Designed for demanding sealing applications involving water pressure and ultra-high pressure, Ruichen Sealing has launched the RC58/RC59 Reinforced Step Combined Seal for Rod. This product features a combination of a reinforced modified PTFE sealing ring and a GB1235-standard O-ring, specifically engineered for unidirectional sealing in reciprocating hydraulic equipment. An optimized, thickened sealing ring design addresses the challenges of sealing low-viscosity media (such as water), while the reinforced structural design significantly enhances ultra-high-pressure resistance.

For high-pressure piston sealing solutions, choose the Ruichen RC53/RC54 Bore Foot Type Combined Seal! This PTFE combined seal is designed for use with GB1235 standard O-rings; its wedge-shaped foot profile balances contamination resistance, low friction, and exceptional pressure resistance, making it ideal for unidirectional reciprocating hydraulic and pneumatic sealing applications.

Ruichen Sealing supplies the RC51 and RC52 Right Angle Combined Seal for Piston. These seals feature a composite PTFE right-angle sealing ring paired with a GB1235-standard O-ring, designed to meet requirements for single-acting piston sealing in hydraulic and pneumatic reciprocating applications. Options for specification selection and bulk purchasing are available.

For high-efficiency, easy-to-install, bidirectional hydraulic seals, the top choice is Ruichen Sealing’s OK Type Combination Seal. This composite seal allows for rapid installation without the need for specialized tools. It features an automatic wear-compensation structure that maintains a stable seal, ensuring reliability even under harsh, high-pressure conditions. With outstanding extrusion resistance and compatibility with large extrusion gaps, it is ideal for sealing applications involving low-viscosity media—such as water—and is available in a full range of specifications from stock.

For bulk procurement, choose the Ruichen Single Lip Combined Wiper Seal. Comprising a filled-PTFE single-lip wiper ring and a rubber O-ring, it delivers powerful, unidirectional wiping action to effectively block external dust and contaminants. It is widely compatible with equipment involving reciprocating, oscillating, and helical movements. This combined wiper seal offers excellent wear resistance, durability, and reliable protection. Ample stock is available; inquiries and orders are welcome, and custom sizing services are offered.

For high-performance unidirectional reciprocating shaft sealing solutions, consider the Ruichen Seal Triangle Combination Seal. Comprising a PTFE triangular sealing ring and a rubber O-ring, it is widely suitable for unidirectional pressure sealing applications in hydraulic and pneumatic reciprocating systems. The seal balances dynamic and static friction, ensures smooth operation without stick-slip, supports long-term oil-free operation, and features a compact design that saves installation space.
Technical Note: For applications involving rod diameters of 30mm or less, a split-type open groove is recommended for installation.
