OPERATING TEMPERATURES
The fittings and valves are not for use with hot water, although they withstand the same temperature as the polyethylene pipe itself. The fittings and valves will withstand sub-zero temperatures.

TOP

CHEMICAL RESISTANCE
Plasson Fittings are supplied, as standard, with Polyacetal split rings and NBR O-rings which are suitable for water. For aggressive chemical applications CPVC split rings and EPDM or FPM O-rings can be supplied to produce a better chemical resistance.
