RS PRO Nitrile Rubber Seal, 4mm ID, 11mm OD, 6mm

Introducing the range of RS PRO Nitrile Oil Seals, ideal for use as seals in driveshafts, crankshafts, hydraulic cylinders, and other general sealing applications in the hydraulic and pneumatic industry. 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.

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

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