​This seal is composed of a toothed sealing ring filled with PTFE material and an O-ring rubber ring, suitable for one-way sealing of hydraulic and pneumatic reciprocating and rotary motion. It has the characteristics of high life, low friction, good sealing, small structural space, and can be used for water pressure sealing.

The RC2052 consists of a square sealing ring made of filled PTFE—featuring an integrated oil reservoir—combined with a rubber O-ring. It offers a long service life, low friction, excellent sealing performance, and a compact design, and is suitable for hydraulic sealing applications.

As industrial capabilities advance, requirements for sealing products have become increasingly stringent, demanding materials that can withstand higher and lower temperatures, higher pressures, and high rotational speeds under conditions of limited lubrication. Selecting the appropriate sealing material for specific operating conditions is crucial.

Qingdao Ruichen New Material Technology Co., Ltd., a subsidiary of Ruichen Sealing, has been granted national utility model patents for its independently developed "high-safety V-ring seal assembly" and "split-type guide seal."
