Nitrile skeleton oil seal
High temperature resistance/oil resistance/wear resistance/stable performance/cost-effective
Strict workmanship durable
High quality raw material quality assurance
Working performance
Nitrile butadiene rubber(designation NBR)Operating temperature: 30-100 degrees Celsius Main features: oil resistance, heat resistance, good wear resistance. Widely used in the production of sealing products, but not suitable for phosphate series hydraulic oil and gear oil containing extreme additives.
Silica gel material (code PMQ or VMQ) Working temperature: 60-200 degrees Celsius, the main features: good heat resistance, cold resistance, compression permanent deformation is small, but low mechanical strength.
Fluorine rubber material (code FKM) Working temperature: 20-200 degrees Celsius, main features: heat resistance, acid and alkali resistance and other chemicals, oil resistance (including phosphate ester series hydraulic oil), suitable for all lubricating oil, gasoline, hydraulic oil, synthetic oil.
Epdm rubber (code EPD or EPM) working temperature: 50-150 degrees Celsius, the main features: good weather resistance, aging resistance in the air, oil resistance, can be resistant to freon and a variety of refrigerants.
Polytetrafluoroethylene (code PTFE) working temperature: 200-260 degrees Celsius, the main features: good chemical stability, good heat resistance, cold resistance, oil, water, steam, chemicals and other media, high mechanical strength, high temperature resistance, good wear resistance; Very low friction coefficient, good self-lubrication.
Polyurethane (code PU)Working temperature: 35-100 degrees Celsius, the main features: good mechanical properties, excellent wear resistance and oil resistance, but the working temperature is not high.

Material introduction and installation instructions
Technical parameter
Fluororubbers (FPM) are organic elastomers composed of fluorinated monomers. Its characteristics of temperature resistance up to 300ºC, acid and alkali resistance, oil resistance is the best oil resistant rubber, radiation resistance, is good high vacuum performance; Electrical insulation, mechanical properties, chemical corrosion resistance, ozone resistance, atmospheric aging resistance are excellent. The disadvantages are poor processability, high price, poor cold resistance, and low elastic permeability. Operating temperature range: -20ºC~+300ºC. Mainly used in the defense industry to manufacture aircraft, rockets on vacuum, high temperature, chemical corrosion resistant sealing materials, hose or other parts and automotive industry.
Product display
We only make high performance seals
Product details
Internal lip design, good sealing, no impact on load. The lip is a one-time molding mold with high accuracy.
High temperature resistance
Fluorine rubber skeleton oil seal has good high temperature resistance, can reach 200ºC, so under the same axle diameter, fluorine rubber than nitrile rubber application speed is much higher.
Corrosion resistance
Fluorine rubber has corrosion resistance, so that fluorine rubber oil seal on the machine liquid, different fuel oil and lubricating oil stability is excellent, most of the organic acids, hydrocarbon benzene and toluene has good corrosion resistance.
A variety of product models are available
(High temperature resistance, low temperature resistance)
