For this configuration, anti-rotation is achieved by using an O-Ring to create a frictional interface between the seal and bore. Although a metal cased lip seal has higher pressure and speed rating, an O-Ring OD lip seal is a good choice economically when application parameters permit. Lower use applications such as food processing equipment, pharmaceutical equipment and environmental shaft exclude can benefit from this design. For friction sensitive applications, a lip seal with O-Ring OD should be considered. In service, a lip seal will experience a short period of break-in, after which time the seal element will reach a steady state condition. This steady condition allows very low, very consistent friction equating to low power consumption and heat generation.


Common Materials Used in this Product


  • The most popular fillers for products are graphite, fiberglass/molybdenum disulfide, carbon fiber and mineral.


Graphite Filled


  • Since graphite is often used as a lubricant, it does not significantly increase the coefficient of friction of PTFE when used as a filler. The low friction allows the compound to be used when both shaft speed and pressure are high. Graphite also is chemically inert which enables its use in corrosive medias.


Proprietary Low Wear PTFE


  • This proprietary filled PTFE offers low wear and friction properties, used in general applications where long life is required. Not recommended for applications with abrasive media.


Molybdenum Disulfide and Fiberglass Filled


  • 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 also inert towards most chemicals.


Carbon Fiber Filled


  • Carbon fiber lowers creep, increases flex and compressive modulus and raises hardness. Coefficient of thermal expansion is lowered and thermal conductivity is higher for compounds of carbon fiber filled PTFE. Ideal for automotive applications in shock absorbers and water pumps.
