Reduction Tee VIEGA 28 x 28 x 22 mm, model 315016, copper fitting

VIEGA reduction tee 28 x 28 x 22 mm is a copper fitting designed to create a branch from a 28 mm supply to a 22 mm outlet. Intended for use in potable water and heating installations, this compact tee provides a durable connection where a reduction in pipe diameter is required. The fitting is manufactured from copper to offer corrosion resistance and reliable performance in residential and commercial plumbing systems.

Advantages

The copper construction ensures good thermal conductivity and long-term resistance to corrosion in typical water and heating environments. Its reduced-diameter branch allows straightforward adaptation between pipe sizes without the need for additional adapters. The compact design supports installation in confined spaces and is compatible with standard copper piping techniques used by plumbing professionals.

Suitable for

• Potable water supply lines where diameter reduction is required
• Central heating circuits and radiator connections
• Domestic and light commercial plumbing systems
• Repair or modification work to adapt existing 28 mm piping to 22 mm branches

Key specifications

• Material: copper
• Connection layout: tee with reduced branch
• Dimensions: main line 28 mm × 28 mm, branch 22 mm
• Application: water and heating systems
• Installation method: suitable for standard copper pipe joining techniques

How to use

Prepare pipe ends by cutting square and removing burrs, then clean and flux the tubing and fitting according to the chosen joining method. Insert pipes fully into the tee sockets and complete the joint using soldering/brazing or the appropriate mechanical joining technique compatible with copper fittings. Ensure correct alignment and support piping to prevent stress on the fitting. After installation, pressure-test the system in accordance with applicable standards to verify leak-free connections.

Usage recommendations

Use this reduction tee in systems designed for copper fittings and follow local codes for potable water and heating installations. When soldering or brazing, observe appropriate safety precautions and use flux and filler material rated for potable water service if required.
