Threaded reducing bush PVC-U male-female PN16

  Data Sheet |   Product Range | Instructional Video

The PVC-U threaded reducing bush PN16 is an industrial-grade pipe fitting designed to transition between two nominal diameters in threaded thermoplastic piping systems. Featuring an external male thread (R taper) and an internal female thread (Rp parallel) conforming to EN 10226-1 and ISO 7-1, this compact component allows for streamlined diameter reductions without requiring additional couplings. Manufactured from premium unplasticised polyvinyl chloride (PVC-U), the fitting ensures dependable mechanical rigidity, dimensional precision, and tight sealing performance in pressurized fluid distribution networks operating up to 16 bar at 20 degrees C.

Engineered specifically for demanding industrial, water management, and process utility installations, this threaded bush exhibits outstanding chemical resistance against diluted acids, alkalis, mineral salts, and chemical dosing agents. The non-corrosive, non-toxic thermoplastic formulation eliminates galvanic corrosion, rust, and scale formation, preserving fluid purity in potable water treatment, aquatic facilities, agriculture, and industrial effluent transport. The precision-moulded thread geometry guarantees accurate thread engagement and vibration resistance, preventing leakage even under continuous operational hydraulic pressures.

Proper installation requires wrapping the male thread with technical PTFE sealing tape, avoiding liquid jointing pastes containing aromatic solvents or plasticisers that could compromise PVC-U integrity. Thread components smoothly by hand before applying moderate torque with a strap wrench to prevent excessive hoop stress on the female fitting. Operating within a temperature range from 0 to 60 degrees C, the fitting provides long-term operational integrity when accounted for temperature-dependent pressure de-rating.
