A flexible joint made of heat resisting synthetic elastomers and moulded in a spherical shape with vanstoned metal floating flanges.
Ideal for air conditioning and sanitary equipment, pumps, refrigerators, blowers, marine piping systems, feed water, drainage systems and such industries as chemical plants, shipbuilding, power generation, building and waste disposal plants.
Suitable for Axial, Lateral or Angular movements. Style FSF joints are not capable of absorbing more than one movement at a time (i.e. non-concurrent), nor absorbing torsional (i.e twisting) movement.
Manufactured from heat and chemical resisting elastomers of special composition superior to natural or chloroprene rubber, reinforced with tough nylon fibre cord. The moulded vanstone flange has imbedded in its wall a high tensile steel wire to ensure rigidity.
These joints are fitted with metal floating flanges drilled to ANSI, BS Tables, JIS and DIN. The most common drillings are ANSI 150, BS Table E and DIN 16.
Note: the flange thicknesses are all basically the same and are not necessarily in accordance with the relevant flange standard.
The standard joint is fitted with plated carbon steel flanges. Hot dip galvanised and stainless steel flanges are also available on special order.
The moulded spherical rubber expansion joints are available in three ranges of lengths. These three ranges are identified as styles FSF, FSFA and FSFB as per the attached specifications.
