Oil Resistant NBR Rubber Gasket Ring DIN 3869 N85 Hardness

             Din3869 profile Rings commonly used for manufacturing various oil resistant gaskets, seals and rubber pipes , NBR

       DIN Profile Rings, according to DIN 3869 are used as axially static soft seals in combination with threaded elements. Common applications include construction machinery, hydraulic presses, injection machines, fittings, hydraulic valves, and threaded tube connections in general industry.

The special shape of Profile Rings enables them to be used in high-pressure applications, compensate for manufacturing tolerances, and provide reliable sealing action. Nitrile rubber has good oil resistance, abrasion resistance, solubility resistance and high pressure oil resistance, but it is not suitable for polar solvents, such as ketones, ozone and nitrohydrocarbons
