45 Degree Reducing Junction

Stormwater 45° Reducing Junction – PVC-U

The Stormwater 45° Reducing Junction is designed to create a branch in stormwater pipework while reducing the pipe size at the branch. This angled junction allows water to flow smoothly between different pipe diameters, minimizing turbulence and ensuring efficient drainage.

Manufactured from rigid PVC-U, this fitting is ideal for domestic and commercial stormwater systems, including gutter and downpipe connections.

Key Features

• 45° Branch Angle – Ensures smooth flow from main pipe to branch.
• Reducing Design – Connects pipes of different diameters for versatile plumbing layouts.
• Durable PVC-U Construction – Resistant to corrosion, chemicals, and biological growth.
• Smooth Internal Surface – Minimizes blockages and reduces friction.
• UV & Temperature Resistant – Suitable for above-ground and underground installation (0–50°C).
• Compliance – Manufactured to AS/NZS 1254 standards.
