VIEGA reducing coupling 22 x 12 mm bronze, model 366865

VIEGA reducing coupling 22 x 12 mm in bronze, model 366865, is a mechanical pipe connector designed to provide a reliable transition between 22 mm and 12 mm pipe diameters. Made from bronze, this coupling is intended for plumbing and heating installations where a durable metal fitting is required. The fitting is suitable for water and heating circuits and other compatible fluid systems that specify bronze components.

Advantages

The bronze construction offers good corrosion resistance and long-term dimensional stability in typical domestic and commercial plumbing environments. The reducing coupling provides a compact and straightforward mechanical joint that simplifies connecting different pipe sizes without complex adapters. Its metal-to-metal design ensures resistance to deformation under normal operating pressures and temperatures commonly found in heating and water distribution systems.

Suitable for

• Domestic and commercial hot and cold water supply lines
• Heating circuits and radiators
• Small-diameter branch connections from larger mains
• Systems requiring bronze fittings for compatibility or specification

Key specifications

• Material: bronze
• Connection sizes: 22 mm to 12 mm reducing coupling
• Type: mechanical reducing coupling for pipe transition
• Application: potable water and heating systems (where bronze is specified)

How to use

Install the reducing coupling by preparing both pipe ends according to the pipe material and local installation standards: cut square, de-burr, and clean the pipe faces. Fit the coupling onto the larger and smaller pipe ends ensuring proper seating and alignment. Tighten or secure the connection using the recommended method for the specific coupling design and the pipe type in use. Verify the joint for correct positioning and test the system under working pressure to confirm leak-free operation before final commissioning.

Usage recommendations

Use the bronze reducing coupling in installations where metal fittings are required by code or application. Ensure compatibility of pipe materials and fluids with bronze, follow local plumbing standards, and conduct pressure testing after installation. Avoid exposing the fitting to aggressive chemicals or environments not suitable for bronze.
