Kayflow 40mm Push-Fit Waste Water Fittings

(Choice of component and colour)

Fast, flexible push-fit connections for high-volume waste

40mm push-fit waste fittings designed for domestic above-ground grey water drainage kitchen sinks, baths, showers, washing machines, dishwashers and other high flow-rate applications. The system assembles instantly with no adhesives or solvents, while the demountable joints allow easy modifications, maintenance and future extensions without cutting pipework.

Manufactured from polypropylene to BS EN 1451, these fittings offer excellent chemical resistance, UV resistance, and reliably handle hot waste water discharges. The UV-stabilised material helps prevent fading and degradation when exposed to sunlight, eliminating the need for painting or additional protective coatings. When used with push-fit fittings, it forms secure, watertight connections via the integral rubber ring seals. The full range — End Cap, Reducer, Coupler, 45° Swept Bend, 88° Swept Branch, 90° Knuckle Bends, and Pipe Clips — covers all standard layout configurations, from simple straight runs to complex directional changes.
