Solvent Weld Waste 40Mm Knuckle - Black

Solvent Weld Waste 40Mm Knuckle - Black

The 40mm Black Solvent Weld Knuckle Bend is a high-durability PVC-u fitting designed for creating sharp 90-degree turns in residential and commercial waste systems. The "Knuckle" design is specifically engineered for maximum compactness, making it the essential solution for plumbing installations where space is severely restricted, such as behind kitchen appliances, under shower trays, or within narrow wall voids.

By using the solvent weld jointing method, this fitting creates a permanent chemical bond that is significantly more resistant to heat, vibration, and accidental impact than standard push-fit alternatives.

Key Features and Specifications

Size: 40mm diameter (Industry standard for kitchen sinks, washing machines, and dishwashers).

Profile: Tight-radius "Knuckle" design for 90-degree directional changes in confined spaces.

Material: High-grade PVC-u, resistant to sustained hot water temperatures and common household detergents.

Jointing Method: Solvent Weld (requires solvent cement for a permanent, molecularly fused joint).

UV Stabilized: The black finish is formulated to resist ultraviolet degradation, preventing brittleness when installed on external building elevations.

Aesthetic Finish: Sleek Black color, perfect for matching modern architectural exteriors, black soil stacks, and rainwater systems.

Common Applications

Kitchen Plumbing: Connecting sink wastes and appliance discharge hoses within tight base units.

Bathroom Renovations: Ideal for shower waste runs where depth is limited beneath the tray or floor joists.
