The Bore Seal, designed and manufactured by Ruichen Sealing Factory, is suitable for unidirectional sealing in hydraulic reciprocating and rotary motion applications. It features a long service life, low friction, excellent sealing performance, compact structure, and easy installation, use, and maintenance. The special sealing lip and optimized thickness design of the seal ensure excellent sealing performance even in harsh media such as cement grout.
