## Long description

VIEGA brass-nickel 3/4 x 12 double connector is a mechanical plumbing pipe union designed to join 12 mm copper or metal pipes to 3/4" threaded fittings. Made of brass with a nickel-plated matte finish, the connector offers a corrosion-resistant interface suitable for potable water, heating circuits and sanitary installations in residential and commercial buildings. The compact, double-ended design facilitates straightforward replacement and extension of existing runs without soldering or extensive pipe modification.
Advantages
The brass construction provides strength and long service life while the nickel matte plating increases corrosion and wear resistance. The double connector design allows connection between a 12 mm pipe and a 3/4" threaded fitting with a secure mechanical joint that is compatible with common plumbing systems. Its compact form factor simplifies installation in confined spaces and reduces the need for additional adaptors.
Suitable for
Joining 12 mm pipes to 3/4" threaded valves, taps and fittings
Domestic potable water supply and branch connections
Heating circuit connections and radiator installations
Replacement of damaged fittings or short repair jobs
Key specifications
Material: brass with nickel-plated matte finish
Connection sizes: 12 mm to 3/4" threaded
Type: double connector / union for mechanical joining
Application: water and heating systems, sanitary installations
Surface: matte nickel for improved corrosion resistance
How to use
Prepare the 12 mm pipe end by deburring and ensuring it is clean and free of oxidation. Thread the 3/4" fitting and hand-tighten to check alignment, then assemble the double connector by engaging the pipe and fitting ends according to the system’s sealing method (e.g., with appropriate sealing tape or approved joint compound if required by the installation). Tighten fittings using standard plumbing tools to the torque recommended for the connected components, avoiding excessive force that could damage threads or deform the connector.
Usage recommendations
Use the connector only in systems compatible with brass fittings and within the operating pressure and temperature limits of the connected piping. Verify sealing materials and thread tape are suitable for potable water if used in drinking water systems. For heating systems, ensure the connector is installed where thermal expansion and mechanical stress are controlled to avoid fatigue or leakage.
