DWV Reducing 90 Degree Junction

DWV Reducing 90° Junction
Size Range: 100mm to 300mm
Colour: Pale Grey
Material: PVC-U (Unplasticised Polyvinyl Chloride)
Compliance: AS/NZS 1260 – PVC-U pipes and fittings for drain, waste, and vent applications

The DWV Reducing 90 Degree Junction is designed to join a smaller branch line into a larger main line at a 90° angle in Drainage, Waste, and Vent (DWV) systems. These junctions allow for smooth directional change in pipe runs, while accommodating size reductions between the main pipe and the branch.

Perfect for both domestic and commercial drainage systems, this junction is ideal for managing waste and vent flows efficiently. The larger pipe fits directly inside the fitting, and the reduced branch connection allows for a smaller diameter pipe to join seamlessly.

Note: All "90 degree" fittings in DWV systems are typically manufactured at an angle between 85° and 88° to assist with proper drainage flow.

Key Features:

• Available in sizes from 100mm to 300mm
• Connects a smaller branch pipe to a larger main line at a right angle
• Manufactured at approx. 85–88° for optimal drainage performance
• Made from high-quality, rigid PVC-U for long-term durability
• Compatible with solvent cement joints (SCJ)
• Suitable for use in sewerage, vents, stormwater, grey water, and black water systems
• Can be installed above-ground or underground
• UV-resistant for limited external exposure

Temperature Range: 0°C to 50°C
Installation: Use solvent cement to securely join with compatible pipework. Allow 24 hours curing time for full mechanical strength.
