Viega pipe fitting transition 20 x 1/2 in brass, polished

Viega pipe fitting transition 20 x 1/2 in brass, polished is a compact brass adapter designed to connect a 20 mm pipe to a 1/2-inch threaded fitting. The polished brass finish provides a smooth surface that resists corrosion and is suitable for visible plumbing connections in domestic and light commercial installations. The fitting is engineered to create a reliable mechanical connection between differing diameters or thread systems, enabling straightforward integration in water supply lines and repair works.

Advantages

The brass construction delivers good corrosion resistance and mechanical strength while the polished surface improves appearance and eases cleaning. Its compact dimensions reduce space requirements in tight installations and the standardized connection sizes ensure compatibility with common plumbing components. The transition fitting simplifies repairs and modifications by allowing direct coupling between metric pipes and imperial-threaded fixtures without extensive rework.

Suitable for

• Domestic potable water supply lines
• Bathroom and kitchen fixture connections
• Plumbing repairs and retrofit works
• Light commercial plumbing installations

Key specifications

• Material: brass with polished finish
• Connection sizes: 20 mm to 1/2 inch
• Type: transition/adapter fitting
• Typical applications: water supply and fixture connections
• Design: compact, mechanical connection

How to use

Prepare the 20 mm pipe end and the 1/2-inch threaded receiving fitting according to standard plumbing practice: clean, deburr and ensure threads or pipe ends are free of debris. Fit the transition adapter onto the 20 mm pipe using the appropriate method for the pipe type (compression, push-fit or soldering) compatible with the adapter design, then engage the 1/2-inch threaded connection, tightening to the recommended torque for the mating components. Confirm alignment and check for leaks under normal system pressure before finalizing insulation or concealment.

Usage recommendations

Use thread sealant or approved tape on the 1/2-inch thread where required by installation standards; follow local plumbing codes for potable water systems. Match the fitting with compatible pipe materials and connection methods to ensure a durable seal and avoid galvanic corrosion when connecting dissimilar metals.
