FP is a one-way sealing ring composed of a stainless steel V-shaped (0-shaped) spring and a filled PTFE U-shaped ring. It is specifically designed for slow to medium-speed reciprocating or rotating motion applications, including hydraulic and air cylinders.

With a wide sealing pressure range from vacuum to ultra-high pressure, it ensures reliable sealing even for low viscosity media and hot melt adhesives. For the pharmaceutical and food industries, the spring cavity can be filled with silicone to prevent contaminants.

U-shaped outer ring: Filled with polytetrafluoroethylene (PTFE)

Spring Components: V-shaped or Type 0 stainless steel 304/316
