DWV Threaded Coupling
Available Sizes: 100mm to 300mm

The DWV Threaded Coupling is a durable PVC-U fitting used to securely join sections of DWV pipework. Designed with an integrated thread, it accommodates threaded access caps—making it ideal for installations that require future inspection or maintenance.

This coupling is essential in systems where a cleanout point or access to the pipe interior is required. The pipe fits inside the coupling, and a threaded access cap (sold separately) can be screwed on for sealing.

Key Features:

  • Provides a reliable join between DWV pipe sections
  • Threaded design enables compatibility with DWV access caps
  • Manufactured from rigid PVC-U, ensuring strength and corrosion resistance
  • Available in sizes 100mm to 300mm
  • Standard pale-grey colour for easy system identification

Applications:

  • Sewer and wastewater systems
  • Vents and drainage pipelines
  • Greywater and blackwater pipe runs
  • Inspection points using threaded caps
  • Stormwater connections (with suitable adaptors)

Installation & Material Notes:

  • For use with solvent cement joints (SCJ); refer to PVC-U installation guide
  • Joints require 24 hours setting time for full mechanical strength
  • Suitable for above-ground and underground installations
  • Limited UV resistance; prolonged sunlight exposure not recommended
  • Performance & Compliance:
  • Temperature range: 0°C to 50°C
  • Complies with AS/NZS 1260: PVC-U pipes and fittings for drainage, waste, and vent applications

The DWV Threaded Coupling is a practical choice for plumbing systems requiring future access, offering long-term reliability and compatibility with standard DWV components.
