½" Brass Compression Straight Coupling — Inline Pipe Connector

Tool-Free Pipe Joining — No Soldering, No Heat, No Fuss

The ½" Brass Compression Straight Coupling is a premium-grade pipe fitting designed to join two lengths of copper, brass, or compatible pipe in a straight inline run — quickly, cleanly, and without any soldering or heat tools. Using a simple compression mechanism with two nuts and olives (ferrules), this coupling creates a watertight, vibration-resistant joint that can be assembled and disassembled with just a spanner. Ideal for repairs, extensions, and new installations where a reliable, removable joint is needed.

Key Features

• Size: ½ inch (15mm) — fits standard ½" copper and compatible pipes
• Body Material: Solid brass — heavy-duty, corrosion-resistant, safe for potable water
• Connection Type: Compression fitting — two compression nuts with olives (ferrules) for tool-free, leak-free joints
• Configuration: Straight coupling — joins two pipes in a direct inline run
• Finish: Natural brass — classic look with proven durability
• Standard: Manufactured to BS/ISO standards for compatibility with standard pipework

How It Works

Slide a compression nut and olive onto each pipe end. Insert both pipe ends into the coupling body. Hand-tighten the compression nuts, then use a spanner to tighten a further 1¼ turns — the olive compresses against the pipe, creating a permanent, watertight seal. No solder, no flux, no heat required. The joint can also be undone and reassembled if needed.

Common Applications

• Joining copper water supply pipes inline
• Repairing burst or damaged pipe sections
• Extending existing pipework runs
• Connecting pipes in tight spaces where soldering is impractical
• Domestic and commercial plumbing installations
• Boiler and heating system pipework
