Conex copper elbow 45° 42 mm model 5040 042000000 – copper pipe fitting

Conex copper elbow 45° 42 mm model 5040 is a 45-degree copper pipe fitting engineered for changing direction in water, heating and refrigeration systems. Manufactured from copper, it is intended for soldered joints or compatible joining methods with copper pipes of 42 mm outside diameter. The fitting is suitable for both domestic and commercial installations where corrosion resistance and durable copper connections are required.

Advantages

The copper construction provides natural corrosion resistance and good thermal conductivity, supporting long service life in potable water, heating and refrigeration systems. Its 45° angle allows smoother directional changes than sharp angles, reducing flow turbulence and pressure loss. The fitting is compatible with standard soldering and joining techniques for copper pipework, enabling secure, leak-resistant joints when installed correctly.

Suitable for

• Domestic plumbing: potable water supply and distribution
• Heating systems: radiators, boilers and central heating circuits
• Refrigeration and air-conditioning copper pipework
• Commercial installations requiring robust copper connections

Key specifications

• Material: copper
• Angle: 45 degrees
• Connection type: designed for soldered/joined copper pipe connections
• Compatible pipe outside diameter: 42 mm
• Typical application fluids: potable water, heating media, refrigerants (installation and local codes permitting)

How to use

Prepare matching 42 mm copper pipe ends by cutting square and cleaning with an appropriate abrasive or cleaning agent to remove oxides and contaminants. Fit the elbow onto the pipe ends, ensuring full insertion and alignment at the required 45° orientation. Use recommended soldering (brazing or soft soldering as appropriate) techniques and flux suitable for copper to form a sealed joint, or follow the joining method specified for your system. Allow joints to cool and inspect for continuity, alignment and leaks before placing the system into service.

Usage recommendations

Verify local plumbing, heating and refrigeration codes and manufacturer instructions for acceptable joining methods and maximum operating pressures and temperatures. Use appropriate safety equipment when cutting and soldering copper pipe, and perform pressure and leak tests after installation.
