Welcome to the Next Generation of Sealing ... - CE Franklin Ltd.

Compressed Fiber Gaskets
Product Range
SF 2401 - A general purpose sheet material reinforced with aramid fibers and bound with
nitrile rubber. SF 2401 complies with the British Standard for compressed fiber sheet sealing
materials - BS 7531 Grade Y. SF 2420 with an SBR (Styrene Butadiene Rubber) is also available.
SF 3300 - A premium quality sheet material reinforced with a blend of aramid and glass fibers
and bound with nitrile rubber. SF 3300 complies with the highest grade of the British
Standard for compressed fiber sheet sealing materials - BS 7531 Grade X. For applications
in split case pumps where a thin, complex gasket capable of withstanding a high surface stress
is required, SF 3500, a variant of SF 3300 is recommended.
Where caustic liquors have to be sealed a variant of SF 3300 reinforced with a blend of aramid
and carbon fibers is offered: this material, SF 5000 is widely used in the pulp and paper
industry.
