Copper reducing tee Conex 5130R for brazed/soldered joints 22×18×22 mm

Conex copper reducing tee 5130R for brazed/soldered joints 22×18×22 mm is a three‑way copper fitting designed to connect copper pipes of two different diameters in potable water, heating and cooling systems. The fitting features a reduced branch (18 mm) and two equal ends (22 mm), enabling a reliable change of direction and diameter in metal piping runs where brazed or soldered joints are required. Made from corrosion‑resistant copper, the tee is suitable for permanent pipe connections in plumbing and HVAC installations.

Advantages

The Conex reducing tee offers consistent wall thickness and precise dimensions to ensure leak‑free brazed or soldered joints. Its copper construction provides good thermal conductivity and corrosion resistance, making it compatible with common soldering and brazing methods used by professional installers. The reduced branch design simplifies transitions between pipe sizes without the need for additional adapters, helping to maintain smooth internal flow and minimize pressure losses.

Suitable for

• Potable water distribution in residential and commercial buildings
• Heating systems including radiators and underfloor heating manifolds
• Cooling circuits and chilled water lines
• Plumbing repairs and new pipe installations where diameter reduction is required

Key specifications

• Material: copper
• Connection method: brazed or soldered joints
• Dimensions: 22 mm × 18 mm × 22 mm (ends × branch × ends)
• Configuration: reducing tee (one reduced branch, two equal ends)
• Application temperature: suitable for typical potable water, heating and cooling service temperatures (installation limits depend on joint filler used)

How to use

Prepare pipe ends by cutting square and removing burrs, then clean both pipe and fitting joint surfaces with an appropriate abrasive or brush to bright copper. Apply suitable flux for the chosen soldering or brazing filler and assemble the pipe into the tee to the correct depth. Heat the joint uniformly with an appropriate torch until the filler flows and creates a capillary seal. Allow the joint to cool naturally and then inspect for continuity and leak tightness before restoring system pressure.

Usage recommendations

Use qualified installers and approved soldering or brazing materials compatible with copper. Follow local codes and manufacturer guidelines for fluxes, filler alloys and maximum service temperatures. Ensure systems are flushed and tested for leaks after installation.
