Standard O-ring options are fluorocarbon, silicone, nitrile and EPDM. This broad foundation of O-ring and PTFE materials can be tailored to suit nearly all applications. FlexiLip profiles are precision manufactured to fit inch-fractional and metric gland geometries. Standardized tooling and machining efficiencies make FlexiLip seals a cost-effective, high production solution.

Construction. The FlexiLip seal body is machined from a wide variety of PTFE composites and other machinable plastic materials. Its ID lip seals dynamically on a shaft and an elastomeric O-ring on its OD for a static, non-rotating, interference fit in a bore.
