Copper 90° single-socket elbow Conex series 5000 18 mm

Copper 90° single-socket elbow Conex series 5000 18 mm is a right-angle fitting made from copper for use with 18 mm copper tubing. It provides a single-socket connection that enables a change of direction in plumbing, heating and cooling pipe runs. The fitting is suited to domestic and commercial installations where a durable copper joint is required for the transport of water or glycol-based heat-transfer fluids.

Advantages

The Conex series 5000 copper elbow offers corrosion-resistant copper construction and a compact 90° profile for space-efficient routing. The single-socket design simplifies installation on one end while maintaining a secure mechanical joint when properly soldered or joined by the approved method. Its compatibility with standard 18 mm copper pipework ensures predictable fit and flow characteristics in typical plumbing and HVAC systems.

Suitable for

• Domestic hot and cold water distribution
• Central heating circuits and radiator connections
• Chilled water and small refrigeration pipework
• Plumbing modifications and tight-space rerouting

Key specifications

• Material: copper
• Angle: 90°
• Connection type: single-socket on one end, plain tube insertion on the other end
• Nominal pipe diameter: 18 mm
• Application temperature range: compatible with common plumbing and heating operating temperatures
• Typical uses: potable water systems, heating and cooling circuits

How to use

Prepare the 18 mm copper tubing by cutting squarely and deburring the tube end before inserting into the socket. Use the appropriate joining method for the Conex series 5000 specification—commonly capillary soldering (cupro-soldering) or the approved mechanical joining procedure—ensuring correct cleaning and fluxing where required. After assembling, allow joints to cool and inspect for alignment and sealing. Pressure-test the system according to local regulations before putting the installation into regular service.

Usage recommendations

Use with compatible 18 mm copper tubing and approved joining consumables. Avoid mixing dissimilar metals without appropriate isolation to prevent galvanic corrosion. Follow applicable plumbing codes and manufacturers' instructions for soldering temperatures, flux selection and pressure testing intervals.
