Copper Reducing Tee Conex series 5000 42 x 35 x 42 mm

Copper reducing tee Conex series 5000 42 x 35 x 42 mm is a three-way copper fitting designed to join pipes of differing diameters. Made from copper, this reducing tee provides a durable, corrosion-resistant branching point where a main 42 mm line splits to a 35 mm branch and continues to a second 42 mm outlet. The Conex series 5000 fitting is intended for use in plumbing, heating and refrigeration systems that require a reliable mechanical connection with flow reduction on one branch.

Advantages

The copper construction ensures good thermal conductivity and long-term resistance to corrosion and scaling in typical water and refrigerant environments. The reducing tee design allows a smooth transition between pipe diameters to maintain stable flow characteristics while providing a robust mechanical joint. Its standardized dimensions make it compatible with common copper piping and joining methods used in professional installations.

Suitable for

• Plumbing distribution lines where a 42 mm main line feeds a 35 mm branch
• Heating systems including radiators and hot-water circuits requiring a reduced branch
• Refrigeration and HVAC pipework where copper pipe transitions are needed
• Repair and retrofit work on existing copper piping networks

Key specifications

• Material: copper
• Configuration: reducing tee with two 42 mm outlets and one 35 mm branch
• Nominal dimensions: 42 x 35 x 42 mm
• Application areas: plumbing, heating, refrigeration
• Connection type: for joining to copper piping using standard soldering/brazing or mechanical joining techniques appropriate for copper fittings

How to use

Prepare mating pipe ends by cutting square and cleaning the surfaces to remove oxide and contaminants. Fit the reducing tee onto the prepared copper pipes and secure according to the chosen joining method (soldering, brazing or approved mechanical joint). Ensure correct alignment and adequate support of the piping to avoid strain on the joint. After joining, inspect the connection and perform a pressure or leak test in accordance with local standards and system requirements before placing the circuit into service.

Usage recommendations

Use appropriate flux and filler material for the selected joining method and follow local plumbing and HVAC codes. Avoid galvanic contact with dissimilar metals unless suitable insulation or dielectric fittings are used. For installations involving refrigerants or pressurized systems, verify compatibility with system fluids and perform pressure testing according to industry guidelines.
