Standard 125mm uPVC Gutter Connector, UV Stabilized, Black

125mm Gutter Connector

The uPVC Gutter Connector is a high-performance fitting designed to facilitate seamless, leak-proof joints between standard lengths of rainwater guttering. Engineered from high-impact unplasticized polyvinyl chloride, this component provides the structural integrity required for residential and light commercial roof drainage systems. It serves as the primary union point, ensuring that water flow remains contained even during periods of heavy precipitation or high-velocity runoff.

Built for the Job

On the job site, reliability in rainwater management is non-negotiable to prevent foundation erosion and dampness in building envelopes. This fitting is designed to withstand the harsh environmental conditions common in East African climates, specifically high UV exposure and rapid temperature fluctuations. The connector incorporates a clip-lock mechanism that allows for quick assembly without the need for specialized tools or solvent cements. Contractors typically utilize this component to extend gutter runs across long rooflines or to repair damaged sections where a clean break has occurred.

• Joining straight lengths of 125mm half-round guttering on residential fascia boards.

• Replacing failed joints in existing rainwater harvesting systems to restore airtight sealing.

• Integrating new roof extensions into the primary drainage infrastructure of a facility.

Product Highlights

Advanced Sealing Technology

The unit features dual-ribbed EPDM rubber gaskets that provide a compression seal to prevent water bypass at the joint interface.

Thermal Expansion Management

• Internal depth allows for 5mm to 10mm of material movement.
• Prevents gutter buckling during extreme heat cycles.

Material Durability

Constructed from UV-stabilized uPVC to prevent embrittlement and color fading over extended outdoor exposure.

Technical Specifications

What’s Included

• 1 x 125mm uPVC Gutter Connector

• 2 x Pre-installed EPDM Rubber Seals

On-Site & Workshop Notes

• Apply a silicone-based lubricant to the rubber gaskets before sliding the guttering into the fitting to ensure a smooth seat and prevent seal displacement.

• Ensure the gutter ends are cut square and deburred to prevent damaging the internal seals during the installation process.

• Observe the expansion markings inside the fitting to allow sufficient space for the PVC to expand in direct sunlight.
