TECE Tece reducing tee 20x16x20 mm brass 760509

TECE reducing tee 20x16x20 mm in brass is a compact plumbing fitting designed to branch a smaller 16 mm line from a main 20 mm run. Manufactured by TECE, this brass reducing tee provides a corrosion-resistant connection suitable for potable water and heating systems where metric copper, PEX or polymer pipes of the specified diameters are used. The fitting is intended to deliver a stable, leak-minimised junction between pipes with different outside diameters while maintaining flow characteristics in residential and light commercial installations.

Advantages

The brass construction offers enhanced durability and resistance to corrosion compared with many non-metallic fittings, supporting long service life in water and heating applications. The reducing tee format simplifies plumbing layouts by allowing a direct branch from a 20 mm main to a 16 mm run without additional adapters. Its compact dimensions make it suitable for confined spaces behind panels or within distribution manifolds, and the material choice provides compatibility with a wide range of common plumbing materials where brass fittings are recommended.

Suitable for

• Branching a 16 mm supply from a 20 mm main in potable water systems
• Small heating circuits and radiator connections using 20 mm and 16 mm pipes
• Domestic plumbing repairs and retrofits where a reduced branch is required
• Installations behind fixtures, inside cabinets, or within manifold assemblies

Key specifications

• Material: brass
• Configuration: reducing tee (side branch at reduced diameter)
• Dimensions: 20 mm x 16 mm x 20 mm
• Application: potable water and heating systems
• Compatibility: for use with pipes of corresponding metric outside diameters (20 mm and 16 mm)

How to use

Prepare the pipe ends by cutting them square and deburring to ensure full insertion and proper sealing. Depending on the piping system in use (copper, PEX or polymer), assemble the reducing tee following the connection method appropriate for the system — for example, compression fittings, push-fit, or soldering where applicable and compatible with brass. Ensure that seals, olives or O-rings specified for the chosen connection method are correctly positioned and that all joints are tightened to the manufacturer-recommended torque or hand-tightened as specified. After installation, perform a pressure test in accordance with local codes to verify leak-free operation before closing walls or panels.

Usage recommendations

Use corrosion-inhibiting practices where dissimilar metals are joined and follow local regulations for potable water installations. Select compatible sealing components and avoid excessive mechanical stress on the fitting during tightening. For concealed installations, verify accessibility for inspection or replacement and conduct a pressure test after completion.
