Transition union PVC-U solvent socket to brass male thread R PN16

  Data Sheet |   Product Range | Instructional Video

The Georg Fischer PVC-U to brass male threaded transition union R provides a secure, demountable connection between thermoplastic piping networks and metallic pipework, instrumentation, or threaded valves. Engineered for demanding industrial and commercial fluid systems, this hybrid PN16 fitting incorporates a metric solvent cement socket on the plastic end and a precision-machined brass component with external taper thread R compliant with ISO 7-1 and EN 10226-1. The union joint is sealed with a factory-fitted EPDM O-ring gasket, delivering dependable hydraulic integrity and complete leak tightness under continuous operational pressures up to 16 bar at 20 degrees Celsius.

Combining unplasticised polyvinyl chloride (PVC-U in RAL 7011) with durable brass, this transition fitting prevents galvanic corrosion across metallic-to-plastic transitions while providing superior mechanical rigidity where threaded connections are subjected to mechanical torque. Conforming to ISO EN 1452-3, the PVC-U body exhibits excellent resistance to a wide variety of chemical media, including dilute acids, alkalis, and saline solutions. Joining the thermoplastic socket is executed via solvent cement socket jointing using approved adhesives such as Tangit, whereas sealing the tapered brass male thread requires non-hardening PTFE tape. Thread pastes containing chemical compounds harmful to PVC-U must be strictly avoided during installation.

This transition union is widely specified across industrial water treatment plants, chemical process infrastructure, municipal potable water systems, and agricultural irrigation networks. The three-piece union structure allows for rapid disassembly and reassembly, streamlining maintenance schedules and pump or valve replacements without disturbing adjacent fixed piping. As an authorised Georg Fischer distributor, BigWeld supplies this fitting across European markets in diameters ranging from d16 mm (3/8 inch) up to d63 mm (2 inch), providing certified engineering components manufactured to strict European industrial standards.
