Product details

PVC Flange Adaptor

Our PVC Flange Adaptor (also known as a Stub End with Flange or Flanged Adaptor) provides a heavy-duty, demountable connection between plain-end uPVC pressure pipes and flanged valves, pumps, tanks, or metallic piping systems. Engineered from high-impact unplasticized polyvinyl chloride (uPVC), this fitting enables easy maintenance, pipeline inspection, and rigid, leak-free mechanical jointing.

Key Performance Features

  • Demountable Jointinging: Allows quick connection and disconnection of pipeline sections, valves, and equipment without cutting the pipe.
  • Precision Bolt-Circle Pattern: Standard bolt hole spacing ensures seamless alignment and mating with ANSI/BS standard flanged fittings and valves.
  • High Pressure Resilience: Reinforced flange collar and robust wall structure handle heavy internal hydrostatic pressure and mechanical stress.
  • Chemical & Corrosion Immunity: Non-metallic uPVC material prevents rust, scale buildup, and chemical erosion in harsh fluid environments.

Applications

  • Connecting main PVC pipelines to pumps, control valves, meters, and storage tanks.
  • Transitioning between plastic and metal flanged piping networks.
  • Industrial fluid routing, chemical processing, and water treatment plants.
  • Agricultural irrigation main lines and commercial plumbing installations.

PVC Male Threaded Elbow (Male Bend 90°)

Our PVC Male Threaded Elbow (Male Bend) enables a clean 90-degree directional transition between a plain-end uPVC pressure pipe and a female-threaded component. Constructed from high-impact unplasticized polyvinyl chloride (uPVC), this fitting combines a solvent-weld socket on one end with precision-molded external male threads on the other, providing a strong mechanical connection at right-angle turns.

Key Performance Features

  • 90° Directional Change: Redirects fluid flow 90 degrees while transitioning seamlessly from solvent-weld piping to threaded mechanical connections.
  • Precision External Threads: Clean male threads ensure a tight, reliable seal when threading into female-tapped valves, pumps, or distribution manifolds.
  • High Mechanical & Pressure Resistance: Designed with heavy wall thickness to handle continuous hydrostatic pressure, vibration, and thermal expansion.
  • Corrosion & Scale Immunity: uPVC material eliminates rust, galvanic corrosion, and mineral buildup for long, maintenance-free service.

Applications

  • Connecting mainline PVC pipes to female-threaded valves, meters, and pump suction/discharge ports.
  • Agricultural and residential irrigation systems, sprinkler off-takes, and riser assemblies.
  • Industrial process lines requiring right-angle transitions to equipment housing.
  • Commercial water supply distribution and HVAC fluid loops.
