Copper Reducing Tee Conex Series 5000 35 x 18 x 35 mm

Conex Series 5000 Copper Reducing Tee 35 x 18 x 35 mm is a solderable copper plumbing fitting designed to create a reliable branch with a reduced central outlet. Manufactured from corrosion-resistant copper, this reducing tee joins two 35 mm runs to an 18 mm branch and is suitable for water, heating and HVAC systems. The fitting is intended for use in systems where a durable, soldered joint is preferred and where dimensional accuracy and material compatibility with copper pipework are required.

Advantages

This Conex Series 5000 reducing tee provides a corrosion-resistant copper construction that supports long service life in potable water and heating applications. Its solderable design enables strong, leak-resistant joints when correctly brazed or sweat-soldered by a qualified installer. The dimensional configuration, with equal larger ends and a reduced central outlet, simplifies transitions between pipe sizes without additional adapters and helps maintain flow characteristics in mixed-diameter runs.

Suitable for

• Domestic and commercial hot and cold water distribution
• Central heating and radiator connections
• HVAC refrigerant and condensate piping where copper is specified
• Plumbing branch-offs requiring reduction from 35 mm to 18 mm

Key specifications

• Material: Copper suitable for soldering/brazing
• Configuration: Reducing tee with two equal larger ends and one reduced central outlet
• Dimensions: 35 mm x 18 mm x 35 mm (ends x branch x ends)
• Connection type: Solder/sweat (requires appropriate flux and filler material)
• Application environments: Water supply, heating circuits, HVAC systems

How to use

Prepare mating copper pipe ends by cutting square, removing burrs and cleaning the outside surface and inner socket with appropriate abrasives or a wire brush. Apply a suitable flux to both the fitting sockets and pipe ends, insert pipes fully into the fitting and perform soldering or brazing to achieve a complete, even fillet around each joint. Allow the joint to cool naturally and then inspect for continuous solder coverage and absence of gaps. Testing the system under working pressure after installation is recommended to confirm leak-free performance.

Usage recommendations

Use trained personnel for soldering or brazing and follow local plumbing codes. Select compatible flux and filler metals for potable water or heating systems, and ensure pipes are supported and thermal expansion is accommodated. Avoid exposure to aggressive chemicals that can accelerate corrosion of copper fittings.
