Copper tee fitting VIEGA 101848, solder connection 15x12x15 mm

VIEGA copper tee fitting 15x12x15 mm is a solder-connection plumbing component designed to create a T-shaped branch in copper pipe systems. Manufactured from copper, the fitting is intended for soldered joints and provides a compact solution for diverting flow or connecting three runs of pipe with the specified diameters. It is suitable for potable water distribution, central heating circuits, and other low-pressure liquid installations where soldered copper connections are required.

Advantages

The tee fitting offers corrosion-resistant copper construction and a geometry optimized for reliable soldered joints. Its differing branch diameters allow connection of pipes with two identical larger ends and one reduced middle outlet, enabling straightforward integration into mixed-diameter copper networks. The component supports durable, leak-resistant soldered connections when installed according to industry-standard practices.

Suitable for

• Potable water supply lines in residential and commercial buildings
• Domestic and commercial hot water heating circuits
• Branching or diverting flow in copper piping systems with 15 mm and 12 mm diameters
• Professional plumbing and repair work requiring soldered joints

Key specifications

• Material: Copper
• Connection type: Solder (capillary) connection
• Dimensions: 15 x 12 x 15 mm (two 15 mm ends and one 12 mm branch)
• Shape: T-branch fitting
• Typical applications: Water supply and heating systems, low-pressure liquid installations

How to use

Prepare copper pipes by cutting to length and deburring the ends to ensure full insertion into the fitting. Clean the outer pipe surfaces and the inner fitting sockets to bright copper using an appropriate brush or abrasive cloth. Apply suitable flux for soldering according to the soldering material manufacturer's instructions. Assemble the pipes into the fitting with full seating, heat the joint evenly with a soldering torch until the flux becomes active, and feed solder into the joint to form a continuous capillary connection. Allow the joint to cool naturally and then inspect for solder coverage and leaks before placing the system into service.

Usage recommendations

Use appropriate personal protective equipment and follow local plumbing codes. Select flux and solder compatible with potable water systems when installing in drinking-water applications. Ensure joints are pressure-tested after cooling and before commissioning to verify leak-tightness.
