The Plasson Reducing Set 63 x 25mm is designed to reduce pipe sizes in various applications. It includes polyacetal split rings and NBR o-rings, which are standard and suitable for water. For aggressive chemical applications, CPVC split rings and EPDM or FPM o-rings and seals are available.
The fittings and valves have the same maximum temperature rating as polyethylene pipe and can withstand sub-zero temperatures. However, they are not intended for use in hot water applications.
