Product Description
21.5mm Knuckle Bend 90° – uPVC Overflow Pipe Fitting
The 21.5mm knuckle bend at a 90° angle is a compact uPVC fitting designed to create a sharp change in direction within overflow waste systems. Commonly used in overflow connections for showers, sinks, baths and similar plumbing layouts, this bend helps route pipes neatly around obstacles and into waste outlets.
Manufactured from robust plastic, this fitting is strong enough to withstand regular use while remaining lightweight and easy to work with. It forms part of standard overflow pipework arrangements and can be joined to other components using solvent weld or push-fit methods depending on your system requirements.

Performance & Durability
Built from quality uPVC, this knuckle bend withstands typical conditions found in overflow plumbing systems. The plastic material resists moisture and environmental wear, helping maintain a leak-free connection over time.
Whether routing overflow pipework around tight corners or directing flow towards a waste detail, this bend offers durable performance and integrates smoothly with other 21.5mm components in your system.
Installation
Fit the knuckle bend by preparing the ends of the overflow pipes to match your preferred jointing method. For solvent-weld systems, apply solvent cement evenly to both the pipe and fitting before joining to create a permanent bond. For compatible push-fit systems, insert the pipe fully into the socket for a secure connection. Ensure all connections are aligned before final fixing.
