The Right Angle Combined Seal for Piston consists of a right-angled sealing ring made of PTFE (or a PTFE composite) and a rubber O-ring; it is designed for single-acting sealing in hydraulic and pneumatic reciprocating applications. It is categorized into the RC51 and RC52 series based on the matching O-ring (compliant with the GB1235 standard). The right-angled sealing ring features a thin-lip design that offers excellent follow-up compensation capabilities, resulting in superior sealing performance.
The product offers a low coefficient of friction and minimal breakout friction. It ensures balanced dynamic and static friction, operates smoothly without "stick-slip" (jerky motion), supports oil-free lubrication conditions, and boasts a long service life.
Its compact structure fits standard grooves and allows for easy installation and maintenance, making it an ideal sealing choice for the piston assemblies of various hydraulic cylinders.
1. Suitable for both hydraulic and pneumatic applications;
2. Excellent sealing performance in both high- and low-pressure environments;
3. Low friction, minimal breakout friction, smooth operation, balanced dynamic and static friction, and no stick-slip;
4. Long service life; suitable for oil-free lubrication applications;
5. Compact design; easy to install and maintain;

Notes: 1. The light-duty series is easier to install in closed grooves wider than 30 mm.
2. Please consult the company regarding installation in closed grooves.
3. For pressures exceeding 40 MPa, use an H8/f8 fit tolerance for the seal base area.
