Polypipe Waste Push Fit Knuckle Bend - 40mm - 90deg - White

This knuckle bend features a 90-degree angle.

The knuckle bend is made from durable polypropylene.

This fitting is designed for 40mm diameter waste pipes.

No, this fitting is specifically designed for push-fit waste systems and is not compatible with solvent weld pipes without appropriate adaptors.

Ensure the pipe is clean, dry, and fully inserted into the fitting until it reaches the insertion mark. The push-fit system is designed to create a secure seal when properly connected.

While polypropylene offers good resistance, it is primarily designed for indoor residential waste water systems. Prolonged UV exposure may affect its long-term properties.

This knuckle bend is part of the Polypipe Waste Systems range and is compatible with other Polypipe push-fit waste components, including traps and overflow solutions.

Ensure pipes are fully inserted into the fitting and the connection is square. Check for debris or damage on the pipe end or inside the fitting's seal. Re-seat the pipe if necessary.

Verify that the pipe is the correct 40mm diameter and that the fitting is not damaged. Ensure the pipe end is clean and free of obstructions. A small amount of silicone lubricant (not petroleum-based) can aid insertion if needed.

Confirm that the pipe has been pushed in far enough to engage the internal sealing mechanism. Check the fitting for any cracks or defects that might compromise its grip.
