Non-Metallic

Flexitallic have developed compressed fibre gasket sheet products approaching, and in some instances surpassing the capabilities of previous materials. Some of these products have been fibre-reinforced grades, manufactured by the traditional calendaring or sheeter process.
Compressed Fiber Flexicarb Graphite

Compressed Fiber
SF 2400

A general purpose sheet material reinforced with Aramid fibers and bound with Nitrile rubber. SF 2400 complies with the British Standard for non-asbestos sheet sealing materials - BS 7531 Grade Y. Suitable for use in applications involving hot and cold water, steam, oils, fuels, gases and a wide range of general chemicals.

Colour: Green
 
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 non-asbestos 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.

Colour: Light Yellow (pigment-free)
 

Flexicarb Graphite

Flexicarb is a pure exfoliated graphite material exhibiting excellent sealing characteristics, withstanding a wide range of temperatures, pressures and chemicals.

  • This homogeneous material is free of respirable fibers, binders and additives. Standard grades are 95% to 98% pure, with a nuclear grade available at 99.5% purity.
  • Flexicarb is extremely conformable giving it the ability to flow into flange surface imperfections. Its low permeability and chemical resistance make it an ideal choice as a sealing material.

The high purity of Flexicarb is chemically inert to most media. (Note its limitations on oxidizing compounds.)

Flexicarb covers a wide temperature spectrum, from cryogenics through elevated temperatures. It can be supplied with an inorganic passivating inhibitor to increase its oxidation and corrosion resistance. Recent experiences and tests have shown that Flexicarb will oxidize over time. Care should be taken when considering the use of Flexicarb foil for applications above 330°C (650°F).
RGS 3

Flexicarb Tanged steel reinforced graphite is a laminate sheet material of graphite foil layers mechanically bonded to a 0.1 mm (0.004”) thick 316 stainless steel Tanged core. The core enhances the mechanical strength of the graphite foil. Flexicarb RGS3 is suitable for sealing steam, water, gasses, hydrocarbons, alkalis and chemicals.
