PVC-C metric spigot to Rp female thread reducing bush PN16

  Datasheet (PDF)

The Georg Fischer (GF Piping Systems) PVC-C metric spigot to Rp female thread reducing bush is an engineered thermoplastic adaptor fitting designed to provide a secure transition between metric solvent cement piping and threaded process equipment. Manufactured from post-chlorinated polyvinyl chloride (PVC-C) in agate grey RAL 7038, this adaptor features a metric spigot end for solvent cement jointing into a metric socket, alongside a parallel female thread (Rp) conforming to ISO 7-1. To prevent stress cracking caused by radial expansion when connecting male fittings, the threaded socket is reinforced with an A2 stainless steel ring. As an authorised Georg Fischer distributor, BigWeld supplies robust industrial piping systems engineered to withstand aggressive chemical environments and elevated operating temperatures.

Rated for PN16 (16 bar) at 20 degrees Celsius, this PVC-C reducing bush operates continuously at temperatures up to 80 degrees Celsius under derated pressure. Post-chlorinated polyvinyl chloride delivers outstanding chemical resistance against aggressive mineral acids, alkalis, and saline solutions where PVC-U or metallic systems fail due to corrosion or thermal softening. The integrated A2 stainless steel collar absorbs hoop stresses during assembly and cyclic pressure pulses, permitting safe mechanical connection to plastic or metal male threads. The fitting meets strict industrial requirements, offering silicone-free execution suitable for automotive paint lines, chemical dosing skids, surface treatment, and water treatment plants.

Installation of the metric spigot involves standard solvent cementing using certified PVC-C cleaner and cement, ensuring a durable, leak-tight bond. For the threaded Rp connection, installers must select thread sealants compatible with PVC-C, such as PTFE tape, avoiding excessive torque. Combining mechanical stability and chemical resilience, this Georg Fischer reducing bush ensures long-term integrity across industrial distribution networks.
