The Ruichen FS-C Multi-Lip Spring-Energized Seal features a unique serrated lip design that significantly enhances sealing performance. The FS-C model is an ideal choice for applications requiring strict leakage control.
It delivers stable, reliable sealing—balancing low friction with long service life—at operating pressures up to 40 MPa (pressures exceeding this limit require a specified wide-groove configuration).
Limit values should not occur simultaneously.

The multi-lip structure of this model creates multiple sealing barriers, ensuring excellent gas and liquid tightness even at low pressures. It is specifically designed for vacuum environments or applications with extremely low pressure differentials, while also accommodating operating pressures up to 40 MPa (provided a widened groove is used).
Ruichen FS-C spring-energized seals deliver exceptional performance in vacuum equipment, analytical instruments, precision measuring devices, and high-specification valves. Their low-friction characteristics and smooth motion make them particularly well-suited for precision motion control applications. Custom-engineered Ruichen FS-C seals ensure long-term sealing reliability for scientific research equipment, medical instruments, and high-precision industrial control systems.
All dimensions within the specified ranges are available.
