The PTFE lip seal 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 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.
Used in this Product
Molybdenum disulfide increases the hardness of the seal surface while decreasing friction. It is normally used in small proportions combined with other fillers such as glass. MoS2 is inert towards most chemicals.
Machined Primary Lip with clockwise or anticlockwise thread.
General purpose rotary shaft seal.
