Filler
CAF / CNAF for industrial gaskets
Compressed asbestos-free (CAF / CNAF) jointing filler for general-purpose sealing.
CAF (compressed asbestos-free jointing, sometimes labelled CNAF) replaced legacy asbestos sheet as the standard general-purpose gasket filler decades ago. It offers dependable, cost-effective sealing across water, steam, and mild chemical duties — the default recommendation whenever a project does not demand PTFE or graphite performance.

Frequently asked questions
Is CAF the same as non-asbestos gasket material?
CAF commonly refers to compressed asbestos-free jointing materials used as a modern alternative to asbestos sheet. Exact performance depends on the specific grade selected for your media and temperature.
Is CNAF gasket material the same as CAF?
Yes. CNAF (Compressed Non-Asbestos Fibre) and CAF (Compressed Asbestos-Free) are two common names for the same category of jointing sheet. We manufacture it in multiple grades for general industrial sealing.
