This oil seal is manufactured from Nitrile rubber (NBR), which is a cost-effective material and is great for applications where the seal needs to be resistant to lubrication oils, hydraulic fluids and grease. With an assortment of metric and imperial sizes available to suit a wide variety of applications, the oil seal also offers long life and good chemical resistance to most hydrocarbons, oils and fuels to aid optimum performance for the life of the oil seal.

Features and Benefits:

This range of RS PRO oil seals are versatile seals that can be used shaft seals, face to face seals, as well as facilitating rotary and linear movement

The single lip design of the seal ensures that the grease, oil or lubricant is kept inside where it’s needed to facilitate optimum performance while preventing the ingress of dirt, water and other contaminants that could impact the operation of the parts

The nitrile material is hardwearing with excellent resistance to chemicals and provides optimum performance and a long-lasting seal life

Operating temperature range: -20°C to 90°C

Ideal for use as seals for crankshafts, driveshafts, hydraulic cylinders where a rotating shaft is lubricated by oil or grease, and other general sealing applications in the hydraulic and pneumatic industry

Available in an assortment of metric and imperial sizes

Applications:

An oil seal is a type of round or donut-shaped seal and is most commonly used to stop fluids or air from passing through into another area. Oil seals are normally seated between two sections and when compressed, they form a secure seal that prevents particle, vapour and fluid leakage which in turn protects and maintains pressure whilst keeping debris out, ensuring proper function and safety. They come in different sizes and materials, depending on the sealing application they are used for, so it is important to consider what materials and fluids are going to be in contact with the seal to ensure it is the right one. Oil seals or gaskets are most commonly used in:

Industrial and manufacturing applications

Plumbing

Hydraulics and pneumatics

Automotive manufacturing and repair

Power transmission technology

How long does an oil seal last?

An NBR oil seal can last up to 15 years if used in the correct conditions and monitored frequently
