1" uPVC Straight Coupling — Solvent Weld Pipe Joiner for PVC Systems

The Essential Pipe Joiner — Strong, Simple & Leak-Free

The 1" uPVC Straight Coupling is a fundamental plumbing fitting designed to join two lengths of 1-inch PVC pipe in a direct inline run. Whether you’re extending a water supply line, repairing a damaged pipe section, or completing a new installation, this coupling provides a permanent, watertight connection using standard PVC solvent cement — no heat tools, no clamps, no specialist skills required. Made from high-grade grey uPVC, it’s corrosion-resistant, lightweight, and built to last as long as the pipe itself.

Key Specifications

• Size: 1 inch (DN25) — fits standard 1" uPVC pipes
• Material: High-grade grey uPVC — rigid, impact-resistant, and corrosion-proof
• Connection Type: Solvent weld socket on both ends — permanent, leak-free bond with PVC cement
• Configuration: Straight coupling — joins two pipes in a direct inline run
• Colour: Grey — standard uPVC fitting colour
• Standard: Manufactured to BS/ISO standards for compatibility with standard pipework

How It Connects

Apply PVC solvent cement to both the pipe ends and the inside of the coupling sockets. Push the pipe ends firmly into both sockets and hold for a few seconds. The chemical bond creates a permanent, watertight joint — stronger than a mechanical connection and completely maintenance-free.
