White Overflow Straight Coupler – 21.5mm

The White Overflow Straight Coupler (21.5mm) is used to connect two sections of overflow pipe where an extended straight run is required. It is commonly fitted in domestic overflow wastewater systems serving toilet cisterns, cold-water storage tanks, and heating appliances.

Manufactured from durable uPVC, the coupler maintains a consistent internal diameter to support smooth water flow through the joint. Its rigid construction ensures accurate pipe alignment, helping reduce movement and maintain a tidy installation once fitted.

Finished in white, the coupler matches standard 21.5mm overflow pipes and fittings for a clean, uniform appearance throughout the system. It forms part of the Overflow Wastewater System 21.5mm, within the wider Wastewater category, and is suitable for both internal and external domestic applications.
