FlexiLip Rotary Seals


The Parker FlexiLip™ is a rotary lip seal that features an ID lip that seals dynamically on a shaft and an elastomeric O-ring on its OD to seal statically in a bore. Since the lip is not spring energized, the radial lip contact forces are lower than a rotary FlexiSeal®, which allows the seal to function at much higher surface speeds (up to 5000 sfpm). The seals are manufactured from a wide variety of PTFE composites and other machinable plastic materials. Standard O-ring choices are fluorocarbon, silicone, nitrile and EPDM. This broad foundation of standard O-ring and PTFE materials can be tailored to suit nearly all applications. Standard and Non-standard FlexiLip™ profiles are precision machined to fit inch-fractional and metric gland geometries. The FlexiLip™ design is extremely versatile because the seal is machined from a molded PTFE sleeve. Standard tooling and programs are used to manufacture seals efficiently by eliminating setup and programming time. FlexiLip™ seals are used in demanding applications where the operating conditions exceed the capabilities of elastomeric seals.
