??Xinhua Xu professional O-ring seal

??Shenzhen Xinhua Xu specializes in producing O-ring seal with oil, high pressure, high temperature, low temperature properties:

??A, NBR nitrile rubber O-ring: Suitable for petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricants, gasoline, water, silicone grease, silicone and other media use. It is currently the most widely used and lowest cost rubber seals. Does not apply to polar solvents being, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform. General temperature range of -40 ~ 120 ?. Heat resistance, cold resistance, oil resistance, water density, abrasion resistance, chemical resistance, resistance to deformation, mechanical, Zhang strong intensity, age 10 years.

??Two, HNBR hydrogenated nitrile rubber O-ring seals: with excellent corrosion resistance, tear resistance, and resistance to compression deformation characteristics, resistance to ozone, sunlight, weather resistance is better. Have better abrasion resistance than nitrile rubber. It applies to washing machines, car engine system and the use of new environmentally friendly refrigerant R134a refrigerant system. Not recommended for use in alcohols, esters, or aromatic solution. General temperature range of -40 ~ 150 ?.
