Reduction Tee VIEGA 22 x 18 x 18 mm – brass plumbing fitting

The VIEGA reduction tee 22 x 18 x 18 mm is a brass plumbing fitting engineered to join a 22 mm main run to two 18 mm branches. Manufactured from corrosion-resistant brass, this fitting enables a smooth diameter transition and a stable three-way connection for domestic potable water and heating circuits when used with compatible pipe materials and appropriate joining methods. The component is intended for fixed plumbing installations in residential and light commercial systems where reliable mechanical strength and watertight joints are required.

Advantages

This reduction tee offers a compact and durable solution for changing pipe diameters while maintaining flow continuity. Brass construction provides good corrosion resistance and mechanical robustness. The symmetrical branch design simplifies routing of two downstream lines from a single 22 mm supply, reducing the need for multiple fittings and potential leak points when installed correctly. The fitting is compatible with common joining techniques used in potable water and heating systems where brass fittings are accepted.

Suitable for

• Domestic potable water distribution where materials and seals are approved for drinking water
• Central heating and hot water circulation in residential buildings
• Light commercial plumbing installations requiring a 22 mm to 18 mm branch split
• Retrofit or extension work where a reduction from 22 mm main to 18 mm feeders is needed

Key specifications

• Material: brass (corrosion-resistant alloy suitable for plumbing)
• Connections: three-way tee with one 22 mm inlet and two 18 mm outlets
• Function: diameter reduction and branch distribution
• Typical applications: potable water and heating systems
• Physical form: compact three-way fitting for fixed pipe installation

How to use

Prepare pipe ends by cutting square and deburring to ensure proper fit and sealing. Select compatible joining method (soldering, press-fit, or approved mechanical connection) according to the pipe material and local plumbing codes. Insert or position the fitting according to the chosen technique, apply appropriate flux or sealing components if required, and complete the joint following manufacturer and standards guidance. After installation, perform pressure testing and inspect all joints for leaks before placing the system into service.

Usage recommendations

Use with pipe materials and sealing systems approved for potable water or heating use; follow local regulations and VIEGA installation instructions. Verify temperature and pressure ratings of the complete system and avoid aggressive fluids or environments not compatible with brass. For connections requiring soldering or brazing, ensure flux and procedures are suitable for potable water applications.
