## Summary description

VIEGA transition nipple coupling in brass, size 18 mm x 1/2" (model 100650). Designed to connect pipes or fittings with a transition from 18 mm tubing to 1/2" threaded connection. Suitable for plumbing and heating systems where a reliable metal transition fitting is required; provides corrosion resistance and mechanical strength for installations and repairs.

## Long description

The VIEGA transition nipple coupling 18 mm x 1/2" brass model 100650 is a compact metal fitting designed to connect 18 mm tubing to a 1/2" threaded connection. Manufactured from brass, the coupling provides mechanical strength and corrosion resistance required in plumbing and heating systems. It enables secure transitions between metric tubing and imperial-threaded components while maintaining flow continuity and leak-tight performance when installed correctly.
Advantages
The brass construction offers durability, good resistance to corrosion and scale, and suitability for potable water applications where compatible with system materials. Its compact design simplifies installation in confined spaces and reduces the need for additional adapters. The coupling supports reliable mechanical and hydraulic performance under typical domestic and light commercial plumbing pressures.
Suitable for
Connecting 18 mm metal or plastic tubing to 1/2" threaded valves, hoses or fixtures
Plumbing repairs and retrofit installations where a metric-to-imperial transition is required
Heating circuit connections, radiator valves, and boiler service points
Key specifications
Material: brass, suitable for water systems
Connection types: 18 mm tube to 1/2" male/female threaded interface
Typical application: domestic and light commercial plumbing and heating systems
Design: compact transition nipple for tight installation spaces
How to use
Prepare the 18 mm tubing by deburring and cleaning the cut end to ensure a smooth seating surface. Thread the 1/2" connection into the corresponding threaded fitting using the appropriate thread sealant or tape where required by the system. Tighten to the manufacturer-recommended torque or until a secure, leak-free joint is achieved. Verify alignment and pressure-test the assembled connection according to local plumbing codes and standards before returning the system to service.
Usage recommendations
Ensure material compatibility between the brass coupling and connected pipes or fittings to prevent galvanic corrosion. Follow system pressure and temperature limits, apply approved sealing methods for threaded connections, and perform a leak test after installation. Use appropriate tools and avoid over-tightening to preserve thread integrity and sealing surfaces.
