## Long description

The VIEGA transition fitting 20 x 3/4 in brass, polished is a mechanical adapter that joins a 20 mm pipe or tube to a 3/4-inch threaded connection. Manufactured from corrosion-resistant brass with a polished surface, it is intended for plumbing and heating systems where a reliable transition between metric and imperial pipe sizes is required. The fitting is suitable for use in residential and commercial installations and is designed for straightforward installation with common plumbing tools.
Advantages
The brass construction provides good resistance to corrosion and mechanical wear while the polished finish offers a smooth surface that is easy to clean and inspect. The transition fitting enables compatibility between metric 20 mm tubing and 3/4-inch threaded components without the need for soldering or complex adaptors. Its compact form factor conserves space in tight assemblies and supports durable mechanical connections in potable water, heating and general piping systems.
Suitable for
Connecting 20 mm copper or plastic pipe to 3/4-inch threaded valves or fixtures
Domestic potable water supply lines
Heating system pipework and radiator connections
Commercial plumbing installations requiring metric-to-imperial transitions
Key specifications
Material: brass (polished finish)
Connection types: 20 mm push/pipe side to 3/4-inch threaded side
Application: mechanical transition between metric and imperial piping
Typical systems: potable water and heating
Installation environment: indoor plumbing and heating installations
How to use
Prepare the 20 mm pipe end by cutting square and deburring to ensure a proper fit. Thread the 3/4-inch mating component with appropriate thread sealant or tape where required by local installation practice. Insert or fasten the 20 mm pipe to the metric side according to the pipe material and joint type, then tighten the threaded side using suitable wrenches without over-torquing. Verify alignment and perform a pressure test in accordance with applicable plumbing standards to confirm leak-free performance.
Usage recommendations
Use compatible pipe materials and follow local plumbing codes. When joining to potable water systems, ensure materials and assembly methods meet drinking water safety requirements. Avoid excessive torque on threads to prevent damage to the fitting; if a sealing compound is used, choose one suitable for brass and for the media transported.
