VIEGA transition fitting 15 mm x 1/2" bronze (model 100025)

The VIEGA transition fitting 15 mm x 1/2" bronze is designed to connect 15 mm metric tubing to 1/2" imperial threaded components in plumbing and heating systems. Constructed from bronze, the fitting provides a corrosion-resistant mechanical joint suitable for both residential and light commercial installations. The compact design allows installation in confined spaces where reliable, leak-free transitions between metric and imperial fittings are required.

Advantages

The bronze material offers strong resistance to corrosion and dezincification in typical water systems, ensuring long-term durability. The fitting provides a secure mechanical connection that maintains fluid-tight performance under standard operating pressures and temperatures. Its compact dimensions simplify installation in tight assemblies and reduce the need for additional adapters. Compatibility with common 15 mm tubing and 1/2" threaded components minimizes inventory and streamlines system integration.

Suitable for

• Connecting 15 mm copper or compatible metric tubing to 1/2" threaded valves, tees, or appliances
• Plumbing repairs and retrofits where metric-to-imperial transition is required
• Heating system pipework and radiator connections
• Residential and light commercial potable water installations

Key specifications

• Material: bronze
• Connection sizes: 15 mm (metric) to 1/2" (imperial thread)
• Application: potable water and heating systems
• Construction: compact transition fitting for confined spaces
• Operating environment: suitable for typical domestic and commercial water service temperatures and pressures

How to use

Prepare the 15 mm tubing by cutting square and deburring the end to ensure full engagement and a proper seal. Thread the 1/2" component to the fitting using appropriate thread sealing method if required for the application (e.g., thread tape or approved sealant) and tighten to the torque recommended by the system/component manufacturer. Insert and fasten the 15 mm tubing according to the tubing connection type (compression, push-fit, or soldered joint) compatible with the fitting. After assembly, pressurize and inspect the joint for leaks and confirm correct operation before returning the system to service.

Usage recommendations

Use the VIEGA transition fitting in accordance with local plumbing codes and the installation instructions of the connected components. Select compatible tubing materials and ensure proper sealing of threaded connections. For systems carrying potable water, verify material approvals and follow any requirements for water contact materials. When working with heating systems, allow for thermal expansion and use appropriate support and insulation where necessary.
