Brass Reducing Coupling TECE 32 x 20 mm – 766506 / 706506

TECE brass reducing coupling 32 x 20 mm is a metallic pipe fitting designed to connect pipes with different outer diameters. Intended for plumbing and heating systems, this coupling provides a direct transition between a 32 mm line and a 20 mm line. The part is manufactured from brass for mechanical strength and corrosion resistance in typical water supply and central heating environments.

Advantages

The brass construction ensures durability and resistance to common forms of corrosion found in potable water and heating circuits. The compact reducing design enables installation in confined spaces and provides a secure metal-to-metal connection without the need for adapters that increase overall length. Suitable for repeated assembly and reliable under pressure when installed according to system requirements.

Suitable for

• Connecting 32 mm pipes to 20 mm pipes in water supply systems
• Transitions in radiator and central heating circulation lines
• Local repairs and retrofits where a sturdy metallic reduction is required

Key specifications

• Material: brass
• Connection type: reducing coupling
• Nominal sizes: 32 mm to 20 mm
• Application: plumbing and heating systems
• Suitable medium: potable water, heating fluids

How to use

Install the reducing coupling by preparing pipe ends according to the chosen joining method (cut square, deburr and clean). Fit the coupling onto the 32 mm and 20 mm pipe ends ensuring full insertion and correct alignment. Tighten or secure the connection per the system's joining method (e.g., soldering, compression, or compatible press-fitting) and observe manufacturer guidelines for torque, heat, or sealing requirements. After installation, perform a pressure test of the circuit to verify leak-free operation.

Usage recommendations

Use compatible joining techniques and seals approved for brass fittings and the specific pipe materials in the system. Avoid excessive mechanical stress and ensure thermal expansion is accommodated in the pipeline layout. Periodically inspect fitted joints during routine system maintenance and after the first pressure cycle.
