VIEGA soldered tee fitting 15 mm (model 100131) for copper pipe connections

VIEGA soldered tee fitting 15 mm is a precision-manufactured copper tee designed for creating a rigid T-branch in 15 mm copper piping systems. Intended for soldered joints, this fitting enables secure connections in potable water supply, heating circuits and general pipe distribution where a durable, leak-resistant soldered joint is required. The fitting's geometry and material compatibility are optimized for capillary soldering techniques commonly used in plumbing and heating installations.

Advantages

The fitting offers a reliable metal-to-metal joint when installed with appropriate solder and flux, providing long-term resistance to leaks and corrosion in copper piping systems. Its 15 mm size matches standard small-diameter copper tubework, allowing straightforward integration with existing supply and distribution networks. Manufactured by a recognized brand in plumbing components, the tee delivers consistent dimensional accuracy for predictable fit-up and solder flow during installation.

Suitable for

• Potable cold and hot water distribution in residential and commercial buildings
• Central heating circuits and radiator connections
• Branching copper pipe runs for washbasins, sinks and appliances
• Repair and modification of existing copper pipe installations

Key specifications

• Material: copper (suitable for soldered joints)
• Connection method: capillary soldering (soldered joint)
• Nominal pipe diameter: 15 mm
• Configuration: T-branch (equal tee)
• Application: potable water and heating systems

How to use

Prepare the copper pipe ends by cutting square and deburring the inner and outer edges. Clean the fitting and pipe surfaces to bright copper using an appropriate abrasive or chemical cleaner, then apply flux to the mating surfaces. Assemble the tee onto the prepared pipes and heat the joint evenly with a suitable torch until the correct solder flow is achieved; ensure solder fully wets the capillary gap. Allow the joint to cool naturally and inspect for complete solder coverage and absence of visible gaps or voids before pressure testing the system according to applicable standards.

Usage recommendations

Use solder and flux types suitable for potable water and heating applications, and follow local codes and safety practices. When working with open flame, ensure adequate ventilation, protect nearby materials from heat, and verify system compatibility with copper fittings. After installation, perform leak and pressure tests before putting the system into regular service.
