Brass compression elbow Conex CONEX COMPRESSION 18 x 1/2" – F031020402--

Brass compression elbow Conex CONEX COMPRESSION 18 x 1/2" is a 90° compression fitting made from brass for joining 18 mm copper or plastic pipe to a 1/2" threaded fitting. The fitting is intended for water supply and heating installations where a compact right-angle change of direction is required and a secure compression joint is preferred. Its brass construction offers corrosion resistance and mechanical strength appropriate for domestic and light commercial plumbing use.

Advantages

The elbow provides a compact and reliable 90° connection without the need for soldering or hot works, reducing installation time and allowing easier modifications. Brass material ensures durability and resistance to scale and corrosion in potable water and central heating systems. The compression design delivers a positive mechanical seal with standard compression olives and nuts, enabling a neat, tool-assisted assembly and disassembly for maintenance.

Suitable for

• Joining 18 mm copper or plastic pipe to 1/2" threaded fittings
• Domestic and light commercial water supply systems
• Central heating piping where a compact 90° turn is required
• Situations where soldering is impractical or not permitted

Key specifications

• Material: brass
• Connection type: compression to female 1/2" thread
• Pipe size compatibility: 18 mm (compression)
• Angle: 90° elbow
• Recommended media: potable water and heating fluids
• Installation method: compression joint with olive and nut

How to use

Prepare the 18 mm pipe by cutting squarely and deburring the end. Slide the compression nut and olive onto the pipe, insert the pipe fully into the elbow's compression socket, then hand-tighten the nut. Using appropriate wrenches, tighten the nut to the manufacturer's recommended turns beyond hand-tight to compress the olive and form a watertight seal. Thread the 1/2" female connection onto the mating male thread and tighten to the correct torque for the application. After installation, inspect the joint for alignment and test under pressure according to local plumbing codes.

Usage recommendations

Use only the correct size olive and nut for 18 mm pipe and avoid over-tightening to prevent damage to the olive or fitting. Ensure pipe ends are clean and free of burrs to achieve an effective seal. For systems carrying potable water, verify compatibility of all materials and follow local regulations for installation and pressure testing.
