Company Advantages
1. oil seal ptfe as an important product in its industry should be designed with teflon ring seal . It features temperature cycling resistance (material degradation, heat ageing
2. Guangdong DSH Seals Technology Co., Ltd will send detailed procedures to teach customers how to install oil seal ptfe. It exhibits improved wear performance and tear resistance
3. oil seal ptfe is representative of teflon ring seal as it has all the merits of teflon gasket . It features a linear load curve and excellent deflection range
4. oil seal ptfe is adequate to widely apply for teflon ring seal for its teflon gasket features. The low permeability makes it unmatched for service in gaseous media


The A type 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 metal 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 O-ring choices are nitrile. This broad foundation of standard O-ring and PTFE materials can be tailored to suit nearly all applications.

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.
