Copper reducing tee Conex series 5000 28 x 15 x 28 mm

Copper reducing tee Conex series 5000 28 x 15 x 28 mm is a solder-type plumbing fitting designed to join three copper pipes where the branch diameter is reduced. It enables a secure, leak-resistant connection between two 28 mm mains and a 15 mm branch, suitable for potable water and typical heating, ventilation and air conditioning (HVAC) systems. The component is manufactured to provide consistent dimensions and material compatibility for standard copper pipe installations.

Advantages

The Conex series 5000 reducing tee offers reliable mechanical strength and good thermal conductivity due to its copper construction, ensuring effective heat transfer in heating circuits and compatibility with soldered joints. Its precision-formed body facilitates accurate alignment and a consistent fit with 28 mm and 15 mm copper tubing. The fitting is suitable for long-term installations in potable water and common HVAC applications when properly installed and soldered.

Suitable for

• Branching a 15 mm supply from 28 mm mains in potable water systems
• Domestic and commercial heating system pipework
• HVAC installations requiring a reduced-diameter branch
• Applications where a soldered copper joint is preferred for durability

Key specifications

• Material: copper
• Connection type: solder (capillary) fitting
• Dimensions: 28 mm x 15 mm x 28 mm (main x branch x main)
• Function: reducing tee for three-way pipe branching
• Compatible with: standard copper tubing of corresponding diameters

How to use

Prepare the copper pipes by cutting square, deburring and cleaning the outer surfaces and fitting bores. Apply appropriate flux to the joint areas, assemble the tee onto the 28 mm mains and 15 mm branch, and heat evenly with a suitable torch until the solder flows to form a complete fillet around each connection. Allow joints to cool naturally, then inspect for full solder penetration and test the system for leaks according to local plumbing standards.

Usage recommendations

Use appropriate flame control and personal protective equipment when soldering. Ensure water is drained from the circuit before heating and follow applicable local codes for potable water and HVAC installations. Select solder and flux compatible with copper and potable water applications.
