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

Copper 90° double-socket elbow Conex series 5000 18 mm is a precision-formed plumbing fitting intended for creating right-angle connections between two copper pipes. Manufactured for potable water and heating installations, this compact elbow provides a corrosion-resistant joint designed to deliver reliable flow direction change in residential and commercial systems. The fitting is compatible with standard 18 mm copper tubing and is suitable for use where socket (cup) soldering or brazing methods are specified.

Advantages

The Conex series 5000 elbow offers dimensional accuracy and a smooth internal profile that reduces flow resistance at the turn. Its copper composition ensures good thermal conductivity and long-term resistance to corrosion in water and heating environments. The double-socket design simplifies alignment of two pipe ends and supports secure, leak-tight joints when installed by qualified soldering or brazing techniques.

Suitable for

• Potable water distribution lines in residential and commercial buildings
• Domestic and commercial heating circuits, including radiator connections
• Service loops and compact pipe runs requiring a 90° change of direction
• Systems using copper socket (cup) soldered or brazed joints

Key specifications

• Material: Copper
• Shape: 90° elbow with double socket
• Connection type: Socket (cup) for soldering/brazing
• Nominal pipe diameter: 18 mm
• Typical applications: Cold and hot potable water, heating systems

How to use

Prepare copper pipe ends by cutting square and deburring the inner and outer edges to ensure full insertion into each socket. Clean the mating surfaces with appropriate abrasives or flux-cleaning tools and apply flux suitable for potable water systems. Insert pipes fully into the sockets, align the assembly at a right angle, and heat evenly while feeding solder or brazing filler according to local plumbing codes and manufacturer recommendations. Allow joints to cool naturally and inspect for continuity and leaks before placing the system into service.

Usage recommendations

Use trained personnel for soldering or brazing to ensure safe and code-compliant joints. Verify compatibility with system pressure and temperature ratings and follow local regulations for potable water and heating installations. Flush the system after installation to remove residues from flux and soldering operations.
