## Long description

The SANHA reducing nipple SANHA-Therm ZWxZZ 28x18 is a mechanical pipe fitting designed to create a compact, secure transition between a 28 mm pipe and an 18 mm pipe. Manufactured for use in heating and plumbing systems, this reducing nipple is suitable for connections between compatible copper and steel pipes and supports reliable fluid transport where a change of diameter is required.

How to use
Prepare the pipe ends by ensuring they are clean, free of burrs and aligned for a straight insertion. Select compatible copper and steel pipes with the specified outer diameters (28 mm and 18 mm). Insert the appropriate pipe ends into each side of the reducing nipple according to the installation method recommended by the system designer or local regulations. Secure the connection using the approved joining technique for SANHA-Therm fittings and the mating material—this may include mechanical compression, soldering, or other compatible methods as specified for the piping system. After assembly, inspect the joint and perform a pressure test according to applicable standards to confirm there are no leaks.
Usage recommendations
Use this reducing nipple only with compatible copper and steel pipe materials and within the pressure and temperature limits of the overall piping system. Follow manufacturer and local plumbing codes for joining methods, support spacing and system testing. When used in heating systems, ensure thermal expansion and support are addressed to avoid undue stress on the fitting.
