Solvent Weld Waste 32Mm 135Deg Knuckle - Grey

Solvent Weld Waste 32Mm 135Deg Knuckle - Grey

The 32mm Grey Solvent Weld 135° Knuckle (also known as a 45-degree elbow) is a specialized drainage fitting used for making gradual directional changes in a waste system. Unlike a sharp 90-degree bend, the 135° angle promotes superior flow characteristics, significantly reducing the risk of blockages and "sludge" build-up in small-bore waste runs.

As a Solvent Weld fitting, it is designed to be permanently fused to the pipework using solvent cement. The grey finish is the industry standard for external waste runs and high-temperature discharge applications, such as from bathroom basins and bidets.

Key Features and Specifications

Size: 32mm (Standard diameter for bathroom basins, bidets, and condensed water outlets).

Angle: 135° (45-degree offset) for smooth hydraulic transition.

Joint Type: Female Solvent Socket x Female Solvent Socket.

Material: High-impact ABS or PVC-u (Grey), resistant to hot water and household cleaning chemicals.

Jointing Method: Solvent Weld (Creates a permanent, molecularly fused, leak-proof joint).

Finish: Standard Grey (UV-stabilized for both internal and external use).

Common Applications

Basin Waste Routing: Navigating around bathroom pedestals or within vanity units to reach the main discharge stack.

Condensate Drainage: Ideal for the 32mm discharge lines from high-efficiency boilers or air conditioning units.

Offset Maneuvers: Using two 135° knuckles together to create a smooth "S-bend" to bypass structural obstacles like joists or wall studs.

Bidet Installation: Specifically sized for the smaller waste outlets common on bidet fixtures.
