The ‘Design Life’ of Fusion Plast compression fittings is 50 years when used to transport fluids at 20°C at a maximum pressure of 16bar. The 50 year period is an historic and somewhat arbitrary figure, however he actual lifespan of fittings is expected to be many decades longer. Fusion Plast PE fittings can be used at temperatures above 20 °C, however the pipe and fitting pressure capacity is reduced.
The fittings are also ideal for sub-zero temperatures above -20°C Celsius.
Fusion Plast PE fittings are made from the finest grades of polyethylene PE100 and hence share the chemical resistance of the parent pipes. When determining suitability for the transport of fluids, it is important that the compatibility of all materials coming in contact with our PE pipes and fittings is checked using the Iplex Chemical Resistance Tool
