VIEGA soldered tee connector 18x15x18 mm model 100582

VIEGA soldered tee connector 18x15x18 mm model 100582 is a compact three-way fitting designed for joining copper or compatible metal pipes in plumbing and heating systems. The tee provides a branch connection with two 18 mm ends and a 15 mm branch, intended for soldered assembly to create a sealed metallic joint suitable for water supply, heating circuits and distribution lines. Its construction supports reliable fluid flow and durable mechanical connection when correctly installed with appropriate soldering techniques.

Advantages

The fitting offers a simple, space-efficient branch solution that integrates with standard copper pipework. Being a soldered connector, it creates a metallic, leak-resistant joint that is suitable for high-temperature and pressurized systems when properly installed. Its mixed-diameter design (18×15×18 mm) allows transitions between pipe runs and branches without additional adapters, reducing the number of joints and potential leak points.

Suitable for

• Domestic and commercial water supply lines
• Heating circuits and radiator connections
• Distribution manifolds and branch lines in copper systems
• Renovation projects requiring compact branch fittings

Key specifications

• Material: compatible with copper and similar metal pipes for soldered joints
• Connection method: soldered (capillary soldering) for permanent metallic joint
• End diameters: two 18 mm inlets/outlets and one 15 mm branch
• Application: potable water and heating systems where soldered fittings are acceptable
• Shape: tee (three-way) for branching pipe runs

How to use

Prepare pipe ends by cutting square, deburring and cleaning the surfaces to be joined. Apply appropriate flux to the cleaned pipe and fitting contact surfaces, assemble the parts with correct insertion depth, and heat the joint evenly until solder flows into the capillary gap. Allow the joint to cool naturally and then inspect for full solder coverage and a continuous fillet. Follow local plumbing codes and manufacturer soldering guidelines for temperature, flux type and solder alloy selection.

Usage recommendations

Use this soldered tee in installations where permanent, metallic joints are required. Ensure all materials are compatible with soldering and rated for the system’s operating pressure and temperature. For potable water systems, select approved solders and fluxes and verify compliance with local regulations. If alternative connection methods (press-fit or threaded) are preferred, choose fittings designed specifically for those systems.
