Compression elbow Conex 15 x 1/2" brass (male) model E031020403--

Conex compression elbow 15 x 1/2" brass is a right-angle plumbing fitting designed to join a 15 mm copper or plastic pipe to a 1/2" male threaded connection. The fitting is manufactured in brass and uses a compression-style joint to create a secure, low-profile connection suitable for potable water and heating systems where a compact elbow is required to connect to valves, radiators, or fittings with a 1/2" male thread.

Advantages

The brass construction provides good corrosion resistance and mechanical strength for domestic and light commercial installations. The compression joint design allows for a reliable, leak-resistant seal without the need for soldering, making installation quicker and suitable for environments where open flames are undesirable. The compact right-angle form factor enables neat transitions between pipe runs and threaded fixtures in confined spaces.

Suitable for

• Connecting 15 mm pipework to 1/2" threaded valves and fixtures
• Domestic potable water supply and heating systems
• Retrofit work and maintenance where solder-free connections are preferred
• Tight or compact installation spaces requiring a 90° transition

Key specifications

• Material: brass body suitable for water systems
• Connection A: compression for 15 mm pipe
• Connection B: 1/2" male threaded outlet
• Type: 90° elbow
• Application: potable water and central heating installations

How to use

Prepare the 15 mm pipe by cutting it square and deburring the cut end. Slide the compression nut and olive onto the pipe, insert the pipe fully into the elbow body, then hand-tighten the nut before applying a final turn with an appropriate wrench to compress the olive and form the seal. Ensure the 1/2" male thread is clean and apply thread sealant or tape if required by the system or local practice before engaging the threaded connection. Check for leaks after pressurizing the system and tighten further if necessary within the torque guidance provided by the installer or manufacturer.

Usage recommendations

Use with compatible 15 mm copper or approved plastic pipe and ensure the olive is correct for the pipe type. Avoid excessive tightening to prevent deformation of the compression olive or fitting. Where required, use appropriate thread sealant on the 1/2" male thread and follow local plumbing codes for potable water and heating installations.
