Premium Grade

Rubber Washers

FDA 21 CFR Food Grade Certified

Rubber Washers

Rubber Washers are seals made of rubber used for sealing two mating parts and eliminating vibration and sound between the parts. Rubber washers ensure tighter sealing as well as avoid corrosion when exposed to a humid atmosphere or where the application is in contact with water or corrosive fluids as compared to metal washers. Western Rubbers manufactures premium grade rubber washers that ensure the best functionality and quality. The washers provided by Western Rubbers have high shock absorbing rates which ensure silent operation especially in devices having high vibration rates.

Elastomers Used for
Manufacturing Rubber Washers

Fluroelastomers (Viton)

Also known as FKM or Fluoroelastomer, it is known to have excellent chemical resistance in comparison to all materials.

Neoprene

Also known as Chloroprene rubber & has chlorine in its polymer chain. Due to this it is naturally fire retardant.

Nitrile

Nitrile Butadiene Rubber known for its swell resistance use in alcohol, petrochemical and other derived fluids.

Natural Rubber

The only available natural rubber sourced from rubber trees, it has one of the best physical properties amongst all elastomers.

Silicone

One of the most versatile synthetic rubbers. Can resist a very wide range of temperatures from -50 to 300 degree celsius.

Hydrogenated Nitrile Rubber (HNBR)

It is a saturated form of nitrile rubber known for physical strength retention and resistance to oil, heat and chemicals.

Ethylene Propylene Diene Monomer (EPDM)

Ethylene Propylene Diene Rubber has excellent weather, heat, and ozone resistance due to saturated polymer chain.
