## Summary description

VIEGA threaded internal tee, model 103767, made of brass with connections 18mm x 1/2" x 18mm. Designed for plumbing installations to branch a threaded 1/2" connection between two 18 mm pipe runs. Suitable for potable water and heating systems where a compact brass tee with internal threads is required for joining pipe and threaded fittings.

## Long description

VIEGA threaded internal tee 18mm x 1/2" x 18mm brass is a compact plumbing fitting designed to create a sealed branch from two 18 mm copper or copper-compatible pipe runs to a central 1/2" internal threaded connection. Manufactured in brass, this tee is intended for potable water and heating systems where a robust metal fitting with a female threaded outlet is required to connect threaded valves, gauges or other accessories while maintaining the continuity of the 18 mm pipe line.
Advantages
The brass construction provides corrosion resistance and mechanical stability in domestic and light commercial installations. The internal 1/2" thread allows direct connection of standard threaded fittings without adapters, reducing leak points and installation time. Its compact geometry and consistent dimensions make it suitable for tight spaces and standard plumbing layouts, ensuring reliable connections when joining pipe runs and threaded components.
Suitable for
Branching potable water distribution lines
Connecting thermostatic valves or gauges to heating circuits
Retrofit installations where a threaded outlet is required
Domestic and light commercial plumbing systems
Key specifications
Material: brass
Connections: 18 mm inlet, 1/2" internal thread outlet, 18 mm outlet
Application: potable water and heating systems
Design: internal (female) threaded central connection
Compatibility: suitable for use with standard 18 mm copper or similar pipe and 1/2" threaded fittings
How to use
Prepare the 18 mm pipe ends by cutting square and deburring to ensure proper fit. Insert or solder the 18 mm pipes to the respective ends of the tee according to the chosen joining method compatible with brass pipe fittings. Once the pipes are secured, screw the 1/2" threaded fitting, valve or accessory into the internal thread using appropriate sealing tape or approved sealant for potable water systems. Tighten to manufacturer-recommended torque values to avoid over-stressing the thread.
Usage recommendations
Use in systems conforming to local plumbing codes and standards. Verify compatibility with pipe material and the intended medium (potable water or heating fluid). When installing in concealed locations, ensure joints are pressure-tested before closing walls or insulation. For long-term reliability, use suitable thread sealants approved for drinking water and follow recommended torque limits for threaded connections.
