The RC2051-B/G Toothed Combination Rotary Shaft Seal consists of a toothed sealing ring made of filled PTFE and a rubber O-ring. It is designed for unidirectional sealing in hydraulic and pneumatic applications involving both reciprocating and rotary motion. Key features include a long service life, low friction, excellent sealing performance, and a compact design. It also delivers outstanding sealing results and minimal frictional resistance in water-hydraulic rotary sealing applications.
It maintains reliable sealing performance even under water-hydraulic rotary operating conditions, effectively reducing shaft surface wear and minimizing the risk of equipment leakage. We welcome inquiries from OEM clients regarding product selection, comparison, and bulk purchasing.
