Copper Coupling Conex Series 5000 22 mm, plumbing connector

Conex Series 5000 copper coupling, 22 mm, is a straight plumbing connector designed for joining standard 22 mm copper pipes in water and heating systems. Manufactured for compatibility with conventional copper tube dimensions, this coupling provides a compact, metallic join that resists corrosion and offers stable mechanical performance in domestic and commercial installations.

Advantages

The coupling is made of copper, which ensures good thermal conductivity and resistance to corrosion in potable water and central heating applications. Its straight design simplifies alignment and insertion of pipe ends, while the precise internal dimensions enable a tight fit with standard 22 mm copper tubing. The metal construction reduces the need for frequent replacement compared to some non-metallic alternatives.

Suitable for

• Connecting copper water supply pipes in domestic plumbing
• Joining copper tubes in central heating circuits
• Repairing or extending existing 22 mm copper pipe runs
• Use in new-build plumbing installations with standard copper tubing

Key specifications

• Material: copper
• Type: straight coupling (slip or push-fit method depends on system compatibility)
• Nominal connection diameter: 22 mm
• Application: potable water and heating pipework
• Corrosion resistance: inherent to copper material

How to use

Prepare the pipe ends by cutting square and deburring both internal and external edges to ensure full insertion and a reliable joint. Slide the coupling onto one pipe end and insert the mating pipe until it reaches the internal stop. Depending on the installation method and system type, secure the joint by soldering, brazing, or using the appropriate approved push-fit or compression fittings if compatible. Follow local plumbing codes and manufacturer guidance for joint preparation, flux, heat application, and cooling to ensure a leak-free connection.

Usage recommendations

Inspect pipes for contamination, scale, or damage before joining. Use correct jointing technique—solder or brazing for traditional installations, or certified push-fit methods where applicable—and pressure-test the system after installation according to local regulations.
