All external (male) threads are tapered. All internal (female) threads ≤ 3”are parallel. (unless stated) Operating Temperatures The fittings are not to be used with hot water, although they withstand the same temperature as the polyethylene pipe itself. The fittings and valves will withstand sub-zero temperatures. Chemical Resistance PLASSON fittings are supplied, as standard, with polyacetal split and grip rings and NBR seals 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.
