RS PRO EPDM O-Ring, 66.04mm Bore, 76.7mm Outer Diameter

Introducing the range of RS PRO EPDM O-Rings, ideal for use as seals for pumps, drive belts, and other general engineering applications in the hydraulic and pneumatic industry. This O-ring is manufactured from EPDM rubber, which is a cost-effective material and is great for applications where the O-ring is exposed to weathering, steam, water and silicone/glycol-based fluids. With a variety of metric and imperial sizes available to suit a wide range of applications, the O-ring also offers long life and good chemical resistance to most hydrocarbons, oils and fuels to aid optimum performance for the life of the O-ring.

An O-ring is a type of round or donut-shaped seal and is most commonly used to stop fluids or air passing through into another area. O-rings 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 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. These seals or gaskets are most commonly used in:

• Industrial and manufacturing applications


• Plumbing


• Hydraulics and pneumatics


• Automotive manufacturing and repair


• Power transmission technology

If the O-ring is used in the correct conditions for the material, EPDM O-rings can last for up to 20 years
