Asbestos free fibre (CNAF, NAF) for steam, water, oil, fuel, gas & general use.
Since the ban of asbestos based gasketing materials, there has been the introduction of many alternative “application specific” grades of material. Unfortunately, gone are the days that one material (CAF) is suitable for most services.
Our range of asbestos free fibre and graphite based materials is second to none.
We stock materials from Garlock, Flexitallic, Klinger, Reinz, and also have our own brand, Greeneseal©, for when a medium quality, cost effective, compressed non-asbestos sheet material is required.
It is based on a blend of aramid and inorganic fibre with a high quality nitrile binder system, suitable up to 440ºC and up to 140 BAR pressure*
