A 90 degree knuckle bend is a specialized plumbing fitting used to change the direction of a 21.5mm overflow or condensate pipe. Unlike a standard “swept” elbow, the knuckle bend features a tighter internal radius, allowing the pipework to sit closer to walls or within tight cabinetry, providing a professional and unobtrusive finish.
In high-performance heating and waste systems, structural integrity is paramount. Using a solvent weld knuckle bend creates a permanent bond between the fitting and the pipe. When used with standard solvent cement, the PVC surfaces fuse together, eliminating the risk of leaks often associated with push-fit or compression fittings in high-vibration or exterior environments.
Whether you are rerouting a boiler condensate line or installing a new cold-water tank overflow, this fitting is fully compatible with all standard 21.5mm white overflow pipes. Its UV-resistant construction ensures it remains robust and maintains its white finish, even when exposed to direct sunlight on external walls.
Diameter: 21.5mm (Internal Diameter to fit over 21.5mm OD pipe).
Angle: 90 Degrees.
Connection Type: Solvent Weld (Chemical Bond).
Suitability: Ideal for ECO HEAT SHOP condensate kits, cistern overflows, and air conditioning drainage.
This knuckle bend is the preferred choice for installers who prioritize a compact, reliable, and aesthetically pleasing drainage solution.
