Threaded reducer PVC-U male-female PN16

  Data Sheet |   Product Range | Instructional Video

The PVC-U threaded reducer (male-female) is an injection-moulded fitting engineered for precise diameter transitions within industrial and utility piping systems. Manufactured from unplasticised polyvinyl chloride, this fitting ensures high mechanical rigidity, dimensional stability, and chemical neutrality. Rated at nominal pressure PN16 (16 bar at 20 degrees Celsius), the component features standard male and female threads conforming to ISO 7-1 standards. As an authorised Georg Fischer distributor, BigWeld supplies this fitting for process lines, water treatment facilities, and distribution skids requiring certified fluid handling performance.

The unplasticised formulation offers robust resistance to inorganic acids, alkalis, salts, and chemical cleaning solutions, preventing corrosion and wall thinning throughout system operation. Its smooth internal hydraulic surface limits pressure drop, mitigates scaling, and prevents microbiological deposition. The material functions across industrial temperature ranges up to 60 degrees Celsius, subject to standard thermal de-rating curves. Free of heavy-metal stabilisers, it meets stringent hygiene criteria for potable water networks while withstanding corrosive environments in chemical processing, municipal filtration, and industrial cooling loops.

Assembly into existing piping skids and manifold ports is executed via threaded connection without solvent welding. Installers must use compatible sealants such as virgin PTFE tape, avoiding jointing pastes or mineral oils incompatible with PVC-U resins. Controlled tightening prevents excess circumferential stress on female threads. Available in transition sizes from 1/2 inch to 4 inch, this reducer pairs reliably with valves, flow meters, and threaded pipe spools across European industrial installations.
