What is Rubberised Cork Washer?

Rubberised Cork Washers are high-performance sealing components specially designed for transformer, electrical and industrial applications requiring reliable leak-proof sealing. Manufactured using a premium blend of quality rubber polymers and natural cork granules, these washers offer excellent compressibility, resilience and oil resistance for long-lasting performance under demanding operating conditions.

 

These washers are widely used in transformers, switchgear equipment and industrial machinery where resistance to oil, pressure and temperature variation is essential. Their superior recovery properties and low side flow under compression ensure tight sealing and reduced maintenance requirements. Rubberised Cork Washers are available in various sizes, thicknesses and customized dimensions as per industrial requirements.
