## Long description

Copper reducing tee VIEGA 28×18×28 mm with gasket, model 633851 is a plumbing fitting made of copper that joins three pipe runs while providing a reduced branch. Supplied with an integrated gasket, the fitting is intended for potable water and heating systems where a reliable seal and durable copper connections are required. The design allows a main 28 mm pipeline to branch to an 18 mm line without additional adapters, simplifying installations that combine different pipe diameters.
Advantages
The copper construction offers corrosion resistance and long service life in domestic and commercial water and heating installations. The integrated gasket provides immediate sealing at the branch point, reducing the need for additional sealing materials and minimizing installation time. The reducing tee supports direct joining of 28 mm and 18 mm copper pipes, ensuring a compact connection with stable hydraulic performance. Its shape and dimensions are compatible with common copper plumbing practices, allowing predictable installation results.
Suitable for
 Potable cold and hot water distribution systems
 Domestic and commercial heating circuits
 Branching from 28 mm supply lines to 18 mm service lines
 Retrofit work where space and component count should be minimized
Key specifications
 Material: copper body with integrated elastomer gasket
 Connections: two 28 mm outlets and one 18 mm reduced branch
 Function: reducing tee for joining three pipe runs with sealed branch
 Typical applications: potable water and heating installations
 Sealing: factory-fitted gasket for immediate leak-tight connection
How to use
Prepare pipe ends by cutting square and removing burrs or oxidation before assembly. Slide the pipes into the corresponding 28 mm and 18 mm inlets until they reach the stop provided by the fitting. Ensure the integrated gasket seats properly around the pipe to achieve a leak-tight joint. If required by local codes or system design, secure the connection with approved fittings technique and pressure-test the system according to installation standards.
Usage recommendations
Use this reducing tee in systems designed for copper components and compatible gasket materials. Verify operating pressure and temperature limits of the overall installation and follow applicable plumbing codes. Avoid aggressive chemical exposure and perform a pressure test after installation to confirm sealing integrity.
