Copper Tee Conex Series 5000 28 mm – plumbing fitting, 3-way tee

Conex Series 5000 copper tee, 28 mm, is a three-way plumbing fitting designed to connect three runs of 28 mm copper pipe of the same diameter. Manufactured from copper, this tee provides a durable, corrosion-resistant junction suitable for potable water and heating systems in domestic and light commercial installations. It is intended for creating branch connections or extending existing copper pipework where a reliable, same-diameter three-way join is required.

Advantages

The Conex Series 5000 copper tee offers a consistent internal bore and secure metal-to-metal connection when used with appropriate joining methods for copper fittings. Its copper construction gives good thermal conductivity and corrosion resistance appropriate for hot and cold water circuits. The simple three-way geometry allows straightforward integration into existing copper networks without the need for reducers or adaptors when all runs use the same 28 mm diameter.

Suitable for

• Branching potable water distribution at 28 mm copper pipe diameter
• Extending heating circuits in domestic and light commercial systems
• Creating three-way junctions in closed-loop hydronic systems
• Repairing or replacing existing same-diameter copper tee connections

Key specifications

• Material: copper
• Connection type: three-way tee for same-diameter joints
• Nominal size: 28 mm (for use with 28 mm copper pipe)
• Application: potable water and heating systems
• Installation environment: domestic and light commercial plumbing

How to use

Prepare the copper pipe ends by cutting square and deburring to ensure a clean fit. Position the tee so each 28 mm pipe fully engages into the fitting. Join the connections using an appropriate method for copper fittings—such as capillary soldering (brazing) with flux and compatible solder, or mechanical joining methods if the fitting is specified for them—following local codes and manufacturers' guidelines. After joining, inspect each joint for correct seating and leak-tightness, and pressure-test the assembled section according to system requirements.

Usage recommendations

Use compatible copper pipe and approved joining techniques for potable water and heating systems. Ensure all work complies with local plumbing regulations and industry best practices. When used in heating systems, protect the fitting from corrosive chemicals and galvanic contact with dissimilar metals by using appropriate isolation or dielectric fittings where required.
