Solvent Weld 21.5Mm Overflow Coupler - White

Solvent Weld 21.5Mm Overflow Coupler - White

The 21.5mm White Solvent Weld Overflow Coupler is a specialized PVC-u fitting designed to join two lengths of 21.5mm overflow pipe. This component is essential for extending discharge runs from cold water storage tanks, cisterns, and modern condensing boiler condensate systems. The solvent weld jointing method ensures a permanent, chemical bond that is far more secure than push-fit alternatives, particularly in areas subject to vibration or temperature fluctuations.

Key Features and Specifications

Size: 21.5mm (Standard UK Overflow size).

Jointing Method: Solvent Weld (requires solvent cement for a permanent, leak-proof chemical fuse).

Material: High-quality PVC-u, providing excellent rigid support and resistance to household chemicals.
