## Long description

VIEGA transition fitting model 729639 is a brass adapter with a female thread size 20 x 3/4 and a polished surface designed for plumbing and heating systems. It provides a reliable mechanical connection between pipes or fittings with differing thread standards, offering corrosion resistance and dimensional stability typical of brass components. The polished finish supports easy cleaning and integrates into visible installations where appearance matters.
Advantages
The brass construction ensures good durability and resistance to corrosion in typical potable water and heating applications. A female 20 x 3/4 thread allows direct connection to compatible male-threaded components without additional conversion parts. The polished finish reduces surface oxidation and simplifies maintenance while maintaining consistent thread accuracy for leak‑resistant joints when installed according to standard practices.
Suitable for
Plumbing repairs where a transition between metric and imperial thread standards is required
Heating system connections and adapters in residential or light commercial buildings
Visible installations where a polished brass finish is preferred for aesthetics
Retrofit work connecting older or mismatched fittings to modern pipework
Key specifications
Material: brass
Thread type: female thread, size 20 x 3/4
Surface finish: polished
Application: plumbing and heating connections
Compatibility: designed to join components with corresponding male threads
How to use
Ensure mating threads are clean and undamaged before installation. Apply an appropriate thread sealant or tape recommended for potable water or heating systems, then hand-thread the fitting onto the corresponding male connection. Tighten using suitable tools, taking care to avoid over‑torque that could deform threads or the fitting body. After assembly, inspect the joint and perform a pressure test according to local plumbing codes to confirm leak‑free installation.
Usage recommendations
Use the fitting within the temperature and pressure limits of the overall system, and follow applicable installation standards and local regulations. Avoid excessive mechanical stress or bending forces on the connection and inspect periodically for signs of wear or leakage, especially after system changes or maintenance.
