FlexiCase Rotary Seals


The Parker FlexiCase™ is a rotary lip seal that features an ID lip that seals dynamically on a shaft and metal casing on its OD to seal statically press-fit into a bore. A gasket is sandwiched between layers of sealing lips and the can to seal off the potential leak path. 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 10,000 sfpm).

The seals are manufactured from a wide variety of PTFE composites and other machinable plastic materials. Standard gasket choices are fluorocarbon, nitrile, EPDM and specialty reinforced paper. Users can choose between stainless steel, cold-rolled steel, zinc plated cold-rolled steel and aluminum. This broad foundation of standard gasket, metal and PTFE materials can be tailored to suit nearly all applications. Standard and Non-standard FlexiCase™ profiles are precision machined to fit inch and metric gland geometries. FlexiCase™ seals are used in demanding applications where the operating conditions exceed the capabilities of elastomeric seals.
