Copper coupling Conex series 5000 18 mm 5270018000000

Copper coupling Conex series 5000 18 mm is a straight copper pipe coupler designed to join 18 mm copper tubing in plumbing, heating and refrigeration systems. The fitting provides a corrosion-resistant mechanical connection between two copper pipes and is suitable for potable water, central heating and other installations that require a direct copper-to-copper joint. It is intended for inline repairs, extensions or new system assemblies where a compact, durable coupling is required.

Advantages

The coupling is made of copper, offering good corrosion resistance and thermal conductivity appropriate for hot and cold water applications. Its simple straight design enables rapid, reliable joining of 18 mm copper pipes without altering the pipe alignment. The product is compatible with standard copper tubing dimensions and can be used in confined spaces due to its compact form factor.

Suitable for

• Joining 18 mm copper water supply pipes in potable water systems
• Connecting copper tubing in central heating installations
• Repairing or extending refrigeration and HVAC copper lines where a copper-to-copper join is needed

Key specifications

• Material: copper
• Connection type: straight inline coupling for copper tubing
• Compatible pipe outer diameter: 18 mm
• Application environments: potable water, heating, refrigeration and general plumbing
• Design: compact, corrosion-resistant mechanical join

How to use

Prepare the existing copper pipes by cutting them squarely and deburring the ends. Ensure pipe surfaces are clean and free of oxidation or contaminants that could affect the joint. Insert each pipe end fully into the coupling until seated, following any rotational or alignment guidance provided by the installer or system requirements. Verify alignment and support the piping to prevent stress on the connection; pressure test the installation according to applicable regulations and standards before putting the system into service.

Usage recommendations

Use this coupling in systems designed for copper-to-copper connections and select jointing methods appropriate to the specific installation (soldering, compression, or press-fit) if required by the system. Ensure compatibility with operating temperatures and pressures of the installation and follow local plumbing codes when performing repairs or new installations.
