The PTFE lip seals is a rotary lip seals 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 lip seal, which allows the seal to function at much higher surface speeds (up to 30m/s).
The seals are manufactured from a wide variety of PTFE composites and other machinable plastic materials. Standard gasket choices are fluorocarbon, nitrile. Metal is stainless steel. This broad foundation of standard gasket, metal and PTFE materials can be tailored to suit nearly all applications.

Machined Primary Lip
|Filled PTFE (such as MoS2/Glass fiber, Ekonol and so on), or Virgin PTFE is available
|Virgin PTFE can meet the requirement of food grade approval. And PTFE oil seal has good anti-friction performance, suitable for harsh working conditions such as poor lubrication, high speed, high temperature and strong corrosive medium. This PTFE oil seals is a low friction type, suitable bearing protection.
