What are the advantages of nitrile rubber oil seals

Due to the different requirements of its rotating oil seal (dynamic seal) or vehicle (shaft motion seal), the characteristics and requirements of the rubber oil seal sealing material are determined by the use conditions. DLSEALS tells you that the current common rubber sealing materials include nitrile rubber, acrylic ester Rubber and fluororubber, you can also choose to use common rubber sealing materials in the industry such as polyurethane, silicone rubber, hydrogenated nitrile rubber, polytetrafluoroethylene, etc.!

Nitrile rubber (NBR)

1. What are the functional characteristics of oil seals made of nitrile rubber? Oil seals (seals) made of nitrile rubber have excellent oil resistance (such as resistance to animal and vegetable oils, liquid fuels and solvents), good wear resistance, heat resistance, aging resistance and good physical and mechanical chemical resistance. Better than rubber, styrene-butadiene rubber and neoprene (this rubber sealing material can be used for a long time at 120℃).

2. What are the disadvantages of oil seals made of nitrile rubber? The disadvantages of oil seals made of nitrile rubber are poor cold resistance, ozone resistance and insulation, and they cannot withstand the corrosion of acidic liquids and gaseous media at high temperatures.

3. In which industries can nitrile rubber oil seals be used (which mechanical equipment or environmental places)? Nitrile rubber oil seals are widely used in aerospace components, liquefied petroleum gas pipelines, transformers, cylinder head gaskets, etc., especially hydraulic and pneumatic transmission seals (such as O-rings, oil seals, cups, high-pressure sealing rings, etc.), but Phosphate ester fluids have poor adaptability and are not suitable for use in oxygenated and brake fluids.
