Non-Asbestos Gaskets & Seals

If your application needs resistance to high temperatures, (Up to 400° C) or high pressures, (Up to 140 Bar), we supply Non-Asbestos gaskets in our full range of materials.

Asbestos gaskets were used in heavy industry, engines and pipelines, until public awareness of diseases linked to asbestos meant that manufacturers had to develop alternative materials for gaskets. The replacement materials they developed are made by compressing fibres, (aramid, inorganic or graphite) with a rubber binder, which is a lot safer than, the now banned, asbestos. They can also be referred to as fibre, CNAF or NAF gaskets.

The rubber binder is usually Nitrile, but there are variations if you need a different binder, like EPDM or SBR, for instance.

We make Non-Asbestos gaskets from our range of materials produced by the world’s leading sheeting manufacturers, including Garlock, Flexitallic, Klinger and Reinz. Unlike CAF (Compressed Asbestos Fibre), there are many different grades of Non-Asbestos gaskets. With our knowledge and familiarity with the materials, we can help you select the right grade for your application.

Our team are experienced at producing all types of Asbestos free gaskets in our gasket shop. We produce standard table gaskets daily, however if you need a bespoke seal making, we will work with your drawings or samples.

We often utilise our two, oscillating knife CAD/CAM cutting tables to produce the gaskets, because we can “Nest” a series of gaskets to achieve the best yield from the material.
