Silicone Bellows

 The silicone multiple bellow expansion joints with support rings have been designed especially to provide small, low weight expansion joints which combine flexibility and high medium temperature with simple installation.
They are suitable for use with cooling water, fuel and lubrication oil pipework systems up to 220°C. The burst pressure safety factor is 3 times the working pressure of 4 bar. The minimum work pressure (absolute) is 80 to 90 kPa, depending on compensator size and can be lowered by fitting vacuum support rings. The mentioned pressures are guaranteed by using the recommended (stainless steel) clamps according to the table.
