## Summary description

Viega transition coupling for pipe connection, size 28 x 1, made of bronze with a polished finish. Designed to join pipes where a 28 mm to 1" threaded transition is required. Suitable for plumbing installations requiring corrosion-resistant metal fittings; used in potable water, heating and general pipework applications.

## Long description

The Viega transition coupling 28 x 1 in bronze with a polished finish is a metal fitting designed to join a 28 mm pipe to a 1" threaded connection. Manufactured by VIEGA for installations where a reliable transition between metric and imperial pipework is required, the coupling offers a corrosion-resistant bronze body and a smooth polished surface suitable for visible plumbing and heating connections. It is intended for potable water, heating systems and general pipework where a durable metal transition fitting is needed.
Advantages
This bronze transition coupling provides dimensional stability and resistance to corrosion compared with standard brass alloys. The polished finish improves surface protection and simplifies cleaning where the fitting is exposed. Its precision-machined threads and seating surfaces ensure a secure threaded connection and reliable sealing when used with appropriate seals or thread tape. The metal construction withstands typical temperatures and pressures found in domestic and light commercial plumbing and heating systems.
Suitable for
 Joining 28 mm copper or compatible metric pipes to a 1" threaded fitting
 Potable water supply installations
 Domestic and small commercial heating systems
 Visible plumbing runs where a polished finish is preferred
Key specifications
 Connection sizes: 28 mm (slip or pipe end) to 1" threaded
 Material: bronze
 Surface finish: polished
 Type: transition coupling for metric-to-imperial connection
 Application: potable water, heating and general pipework
How to use
Prepare the pipe ends by deburring and cleaning to ensure a proper fit. Install the 28 mm pipe into the coupling using the appropriate joining method for the pipe material (e.g., soldering, brazing, or compression where applicable) while observing manufacturer guidelines for heat and flux if soldering or brazing. Engage the 1" threaded connection and tighten to the required torque, using compatible sealing methods such as thread sealant tape or approved pipe thread sealant to achieve a leak-tight joint. Follow applicable local plumbing codes and VIEGA installation instructions for best results.
Usage recommendations
Verify compatibility of pipe materials and joining methods before installation. Use appropriate sealants on the threaded connection and avoid excessive torque that could deform threads or seating surfaces. Where used in potable water systems, follow local regulations regarding materials in contact with drinking water and perform pressure testing after installation.
