Copper 45° Elbow Connector Conex series 5000 18 mm

Copper 45° elbow connector Conex series 5000 18 mm is a precision-formed copper fitting intended for creating a smooth 45-degree change of direction in copper pipe systems. Manufactured by Conex, this fitting is designed for soldered joints in plumbing, heating and refrigeration applications. The 18 mm diameter suits standard small-bore copper pipelines used in domestic and light commercial installations, providing a reliable joint with good thermal and corrosion resistance inherent to copper.

Advantages

This 45° elbow connector offers compact directional change with minimal flow disturbance and a reduced risk of leak points when properly soldered. Copper construction ensures long-term durability, thermal conductivity for heating circuits, and compatibility with common soldering techniques. The fitting’s smooth internal profile supports steady fluid flow and is resistant to common water and heating system conditions.

Suitable for

• Domestic hot and cold water supply pipelines
• Central heating and radiator connections
• Refrigeration and HVAC copper lines
• Small-bore commercial plumbing installations

Key specifications

• Material: copper
• Angle: 45° bend
• Connection type: solderable (capillary) joint
• Nominal pipe diameter: 18 mm
• Typical application temperature range: suitable for potable water and heating circuits (refer to system limits)

How to use

Prepare the copper pipe ends by cutting square and chamfering the inside edge, then clean both pipe and fitting with appropriate abrasive cloth or brush to remove oxides. Apply flux to the joint areas, insert the pipe fully into the fitting, and heat evenly with a suitable torch until the solder flows into the joint by capillary action. Allow the assembly to cool naturally and then remove any excess flux. Ensure the completed joint is pressure-tested according to local plumbing codes before commissioning.

Usage recommendations

Use approved lead-free solder and flux suitable for potable water systems. Follow local regulations and industry best practices for soldering and pressure testing. For systems operating at higher temperatures or aggressive environments, verify material compatibility and consider protective measures to prevent galvanic corrosion where dissimilar metals are present.
