As a manufacturer specializing in high-pressure seals, Ruichen Sealing offers the "Foot-type Combined Seal." The sealing ring features a thin-lip structure that provides excellent dynamic compensation capabilities. Its unique foot-shaped sealing surface—incorporating a wedge-shaped groove—enhances contamination resistance and reduces friction; this specialized design significantly boosts pressure resistance, making it suitable for high-pressure and ultra-high-pressure applications. Note: This seal is not suitable for installation in closed grooves.
We welcome inquiries regarding selection and bulk orders from engineering equipment purchasers.
The Foot-type Combined Seal consists of a foot-shaped sealing ring (made of PTFE or PTFE composites) paired with a rubber O-ring; it is designed for single-acting sealing in hydraulic and pneumatic reciprocating applications.
It is categorized into the RC03 series and the RC04 series (which utilizes GB1235 series O-rings) based on the accompanying O-ring. The sealing ring features a thin-lip design that offers superior dynamic compensation, resulting in excellent sealing performance. The wedge-shaped groove on the foot-shaped sealing surface improves sealing integrity and contamination resistance while reducing friction. The structural design also enhances the seal's pressure-handling capabilities. Generally, it cannot be installed in closed grooves.
1. Suitable for both hydraulic and pneumatic applications
2. Excellent sealing performance in both high-pressure and low-pressure environments
3. Low friction; minimal start-up resistance and smooth movement; equal dynamic and static friction; no stick-slip effect
4. Long service life; suitable for oil-free lubrication applications
5. Capable of handling high-pressure and ultra-high-pressure sealing requirements

Notes: 1. For pressures >60 MPa, use an H8/f8 fit tolerance at the seal base area; for ultra-high-pressure sealing, Smax < 0.05.
2. Please consult the office if a closed-groove structure is required.
Compatible with GB1235 O-rings; products of any size listed in the specification table can be manufactured.
