About us

Jehbco Silicones is a world-leading manufacturer of quality silicone extrusions and gaskets.

Founded in 1974 by four partners, Jim, Eric, Hank and Burt (with the initials forming JEHBCO) in a small industrial factory in Sydney with only a small extruder and mill, 45 years later Jehbco is an Australian-owned family run business with all manufacturing done on-site. From humble beginnings Jehbco now has five extruder lines, a wire cutter, two mills and the capability to make all dies and tooling on-site.

Being a small business has allowed Jehbco to be dynamic and agile, reacting to changes within industries quickly. The company has been able to meet the demand for specialty products that are fire, UV, oil, heat and weather resistant for industries such as mining, pharmaceutical, construction, defence and transport.

We take pride in our good customer service and we always endeavour to find a custom solution to our customer’s problems.
