Adaptor Union PVC-C and Malleable Iron d20-63 Male Thread R

  Datasheet (PDF)

The Georg Fischer (GF Piping Systems) PVC-C and malleable iron adaptor union is an engineered hybrid transition fitting designed to connect metric solvent cement thermoplastic piping to threaded metal systems. Composed of a chlorinated polyvinyl chloride (PVC-C) solvent cement socket bush, a robust PVC-C union nut, and a galvanized malleable iron threaded end with male taper thread (R), this modular component enables seamless mechanical integration between dissimilar materials. An integrated EPDM O-ring gasket guarantees tight elastomeric sealing across demanding industrial operating environments, maintaining joint integrity at elevated temperatures up to 80 degrees Celsius.

Engineered for demanding chemical processing and industrial utility networks, this adaptor union resolves interface challenges between rigid plastics and metal assemblies. The three-piece union architecture permits straightforward radial installation and rapid disassembly without displacing adjacent pipe runs, making it ideal adjacent to pumps, instrumentation, and metal valves. The male taper thread (R) provides secure jointing into female threaded fittings, while the metric solvent cement socket delivers durable, leak-tight fusion to RAL 7038 Agate Grey PVC-C pressure pipes.

The post-chlorinated PVC-C compound delivers superior chemical resistance against aggressive acids, alkalis, and salts compared to conventional PVC-U, ensuring dependable performance in chemical process lines, industrial water treatment, and surface treatment facilities. The hot-dip galvanized malleable iron component provides the structural rigidity and impact resistance necessary to withstand mechanical loads and external pipe stresses. As an authorised Georg Fischer distributor, BigWeld supplies genuine GF piping systems engineered in compliance with ISO 727 and ISO 15493 standards.
