Copper reducing tee Conex series 5000 18 x 15 x 18 mm

The Conex series 5000 copper reducing tee 18 x 15 x 18 mm is a three-way plumbing fitting designed to join copper pipes where a reduced branch is required. Manufactured for use in potable water and heating systems, this reducing tee provides a corrosion-resistant joint suitable for soldering or brazing into existing copper pipe networks in both residential and commercial installations. The fitting’s concentric design ensures predictable flow distribution and a neat connection between main runs and the smaller branch.

Advantages

The Conex series 5000 reducing tee is made from copper to deliver reliable corrosion resistance and long service life in typical water and heating applications. Its reduced branch simplifies transitions between different pipe diameters without the need for additional adapters. The fitting is compatible with standard soldering and brazing techniques used in copper plumbing, allowing a secure, leak-resistant joint when installed correctly.

Suitable for

• Potable water distribution systems
• Domestic and commercial heating circuits
• Pipework requiring a step down in diameter
• Installation where copper fittings are specified

Key specifications

• Material: Copper
• Configuration: Reducing tee (three-way)
• Dimensions: 18 mm x 15 mm x 18 mm (main run x branch x main run)
• Connection method: Soldering or brazing compatible
• Application: Potable water and heating systems

How to use

Select appropriate lengths of copper pipe and prepare pipe ends by cutting square and cleaning with an appropriate abrasive cloth or brush. Apply suitable flux to the joint faces, assemble the reducing tee onto the pipes, and heat evenly with a suitable torch until the solder or brazing material flows to form a continuous fillet around each connection. Allow the joint to cool naturally before testing. Follow local plumbing codes for support, alignment, and pressure testing after installation.

Usage recommendations

Ensure the fitting is used with compatible copper pipe dimensions and that soldering or brazing is performed by a competent tradesperson following safety guidelines. Do not mix dissimilar metals without appropriate isolation to avoid galvanic corrosion. Verify system pressure ratings and local regulations for potable water and heating installations before use.
