The 65mm square downpipe connector (manufacturer reference: estimated as ASS1W) is a straight jointing component used in exterior rainwater management systems. Designed to seamlessly join two lengths of standard 65mm square downpipe together, this fitting enables the creation of extended vertical pipe runs that reach from high rooflines down to the ground-level drainage point.
Formed from unplasticised polyvinyl chloride (uPVC), the connector features an intuitive double-socketed push-fit mechanism. The straight ends of the square downpipes slot securely into the top and bottom of the fitting, creating a firm and reliable connection without the need for sealants, glues, or specialist tools. This component integrates perfectly into broader
The uniform white finish provides UV resistance, protecting the component from structural degradation and colour fading caused by direct sunlight. Its smooth internal bore ensures a consistent water flow rate and minimizes the risk of debris snagging on the internal joints.
- Connects two lengths of 65mm square downpipe for extended vertical drops.
- Designed with a 65mm profile to fit standard square rainwater pipes.
- Made from lightweight uPVC to resist weathering and corrosion.
- Socketed push-fit design allows rapid, tool-free assembly without sealants.
- UV-resistant white finish prevents fading from direct sun exposure.
