Oil seals made of HNBR are characterised by excellent properties that include high resistance to mineral oils with additives, low steam and gas permeability, good cold flexibility down to -30 °C depending on type, good ozone resistance and friction resistance. HNBR seals withstand heat up to 150°C.

Nitrile is suitable for environments that have a temperature range of -30 degrees Fahrenheit to 250 degrees Fahrenheit. It is compatible with a variety of fluids, such as hot & cold water, silicone oil, animal & vegetable fat, hydraulic fluid, and gas oil. Nitrile is also a perfect material to use for any application that needs shock absorbers as it’s resistant to grease and abrasion.

Oil seals are used in any industrial application that has a rotating or moving part assembly. This includes:
To ensure correct fit and proper protection against contaminants, the inside diameter of an oil seal must be slightly smaller than the shaft diameter.
Oil seal: get to know all the details about this component
An oil seal is a device used to prevent dirt, dust, water, or any other foreign matter from contaminating shafts and bearings in the rotary shaft equipment. Also known as a shaft seal or dirt seal, it also blocks the leakage of lubricants such as grease and oil along a rotating shaft.
The group of oil seals used in dynamic applications include radial shaft seals that seal a rotating shaft around its circumference. They are also known as lip seals, but in this blog we will use the term oil seals.
Rubber O.D. wall type Provides stable sealing performance around the seal O.D. surface.
With minor lip type Used for applications where there are contaminants, such as dust and foreign matter, on the air side face of the oil seal.
