## Summary description

VIEGA transition fitting for connecting 25 mm pipe to 3/4 in threaded connection. Made of copper with a polished finish, model 607999 (EAN 4015211607999). Designed for reliable mechanical and hydraulic connection in plumbing systems, heating installations and sanitary applications where a 25 mm pipe must be adapted to 3/4" fittings or valves.

## Long description

VIEGA transition fitting for connecting a 25 mm copper pipe to a 3/4 inch threaded connection. The fitting is manufactured from copper with a polished surface to provide a smooth, corrosion-resistant external finish. It is intended for use in plumbing, heating and sanitary systems where a straight mechanical and hydraulic transition is required between metric 25 mm tubing and imperial 3/4" threaded components such as valves, hoses or fixtures.
Advantages
The copper construction ensures good thermal and corrosion performance in potable water and heating circuits. The polished finish reduces surface oxidation and facilitates installation in visible locations. The transition fitting provides a secure, dimensionally accurate interface between 25 mm pipework and 3/4" threaded connections, reducing the need for additional adapters and minimizing potential leak points when installed correctly.
Suitable for
Joining 25 mm copper pipe to 3/4" threaded valves and fittings
Domestic and commercial potable water supply lines
Heating system connections and radiator hookups
Sanitary installations where metric-to-imperial adaptation is required
Key specifications
Material: copper
Connection A: 25 mm smooth pipe connection
Connection B: 3/4" male or female threaded connection (3/4-inch)
Surface finish: polished
Intended media: water for plumbing and heating systems
How to use
Ensure the 25 mm pipe is cut square, deburred and cleaned before fitting. Slide or push the pipe into the 25 mm end or prepare it according to the joining method compatible with the fitting (soldering, press or compression depending on the specific product variant and installer practice). Tighten the 3/4" threaded connection to the mating component using appropriate sealing method on the thread (such as PTFE tape or approved thread sealant) and torque values recommended for the mating fitting. Verify alignment and check for leaks under pressure after installation.
Usage recommendations
Use appropriate personal protective equipment and follow local plumbing codes. Match the fitting type to the intended joining method (solder, press, or compression) and use thread sealant compatible with potable water systems on the 3/4" threads. Perform a pressure test after installation to confirm leak-free operation.
