VIEGA soldered tee fitting 28x18x28 mm, model 102852

VIEGA soldered tee fitting 28x18x28 mm, model 102852 is a copper tee designed to connect three soldered copper pipes: two run pipes with 28 mm diameter and a central branch of 18 mm. The fitting is intended for professional plumbing and heating installations where a reliable soldered joint is required for the transport of potable water, heating medium or other compatible fluids. The compact shape and standard dimensions make it suitable for integrating into common domestic and light-commercial pipework systems.

Advantages

The soldered tee offers stable mechanical strength and corrosion resistance inherent to copper materials, ensuring long-term durability in potable water and heating applications. Its predictable dimensions and smooth internal passage promote consistent fluid flow and minimise turbulence at the junction. Because it is soldered, the joint provides a leak-resistant and rigid connection when installed correctly by a qualified fitter.

Suitable for

• Potable water distribution systems
• Domestic and commercial heating circuits
• General copper pipework and plumbing repairs
• Systems requiring soldered/capillary connections

Key specifications

• Material: copper
• Connection type: soldered/capillary
• Run pipe diameter: 28 mm (two outlets)
• Branch pipe diameter: 18 mm (central outlet)
• Shape: tee (T-junction)
• Application temperature: compatible with standard potable water and heating temperatures when used with appropriate solder and installation practice

How to use

Prepare the copper pipes by cutting squarely and deburring the ends, then clean the pipe ends and fitting sockets to bright copper using an appropriate abrasive and degreaser. Apply flux suitable for potable-water-compatible soldering to the mating surfaces. Assemble the tee and pipes, ensuring full insertion, then heat the joint evenly with an appropriate torch until the solder flows into the joint by capillary action. Allow the joint to cool naturally and remove any excess flux. Verify the connection by pressure testing the system according to applicable local standards.

Usage recommendations

Use only flux and solder alloys approved for potable water if the installation carries drinking water. Ensure soldering is performed by trained personnel and follow local codes for brazing/soldering temperatures, ventilation and fire safety. Inspect and pressure-test the assembled system before commissioning.
