## Summary description

Transition coupling SANHA Nirosan Industry for joining copper and steel pipe fittings. Model 618270G2834 with nominal sizes 28 x 3/4, designed as a C-Stahl (steel) threaded connection on one side and compatible copper-side connection. Used in plumbing and heating systems to connect dissimilar materials, ensuring mechanical and hydraulic continuity in water and heating installations.

## Long description

Transition coupling SANHA Nirosan Industry 28 x 3/4 C-Stahl is designed to join copper and steel pipe fittings in plumbing and heating systems. This coupling provides a mechanical and hydraulic connection between dissimilar materials, combining a steel-threaded side with a compatible copper connection. It is intended for installations where copper piping must be connected to steel components while maintaining system integrity under typical water and heating conditions.
Advantages
The coupling ensures reliable mechanical connection between copper and steel pipes, reducing the need for complex adapters. Its combination of materials minimizes galvanic corrosion risks when installed correctly and allows secure threaded assembly on the steel side. The product's construction supports stable flow characteristics and maintains sealing performance suitable for water and heating applications.
Suitable for
 Connecting copper tubing to steel threaded fittings in residential plumbing systems
 Joining copper pipes to steel components in heating installations (radiators, boilers, manifolds)
 Retrofit work where existing steel threads must be connected to new copper lines
 Service and repair jobs requiring transition between copper and steel materials
Key specifications
 Nominal size: 28 mm (copper side) x 3/4 inch (steel threaded side)
 Material combination: copper-compatible connection and steel threaded connection
 Connection type: threaded on steel side, compatible joining method for copper side
 Application medium: potable water and heating circuits
 Typical installation environment: indoor plumbing and heating systems
How to use
Prepare both pipe ends by cleaning and deburring. Ensure the steel threaded fitting is compatible and in good condition. Assemble the copper side according to the appropriate joining method (soldering, press-fit, or other copper-compatible technique) recommended for the installation; then thread the steel side into the mating steel component, using appropriate sealing material or tape where required. Tighten to the torque recommended for the thread size and verify alignment to avoid stress on the joint. After assembly, perform a pressure test of the circuit according to local regulations and standards to confirm leak-free operation.
Usage recommendations
Installers should follow applicable plumbing and heating codes and consider corrosion mitigation measures when joining dissimilar metals. Use compatible sealing materials on the steel threads and verify that the selected copper joining method is appropriate for the system pressure and temperature. If uncertain about compatibility or installation technique, consult technical documentation or a qualified installer.
