## Summary description

SANHA SANHA-Therm ZWxZZ 42ax22 is a reducing nipple (reduction coupling) designed for joining pipes of different diameters in heating, cooling and sanitary installations. Made for use with metallic pipe systems, it provides a secure transition from 42 mm to 22 mm pipe connection. Suitable for hot-water heating, radiators and refrigeration circuits where a reliable mechanical and fluid-tight reduction is required.

## Long description

SANHA SANHA-Therm ZWxZZ 42ax22 is a reducing nipple (reducing coupling) engineered for metal pipe systems in heating, cooling and sanitary installations. It creates a mechanically secure and fluid-tight transition from a 42 mm connection to a 22 mm connection, allowing integration of different pipe diameters in hot-water heating, radiator connections and refrigeration circuits. The part is intended for use where a durable metallic reduction is required and where compatibility with standard metallic pipe fittings is needed.
Advantages
The reducing nipple provides a compact and robust connection that maintains mechanical stability and leak resistance under typical operating conditions of heating and refrigeration systems. Its metal construction ensures long service life and compatibility with metallic pipes and fittings. The design minimises pressure loss at the transition and facilitates straightforward installation into existing pipework without the need for complex adapters.
Suitable for
Hot-water heating systems and radiator branch connections
Cooling and refrigeration circuits with metallic piping
Sanitary installations requiring a reduction from 42 mm to 22 mm
Repair or modification of existing metallic pipe networks
Key specifications
Function: reducing nipple / reduction coupling for metallic pipes
Connection sizes: 42 mm to 22 mm
Application areas: heating, cooling, sanitary installations
Material type: metal suitable for heating and refrigeration systems
Sealing: designed to provide fluid-tight mechanical connection
How to use
Prepare the mating pipe ends by cutting square and deburring to ensure a clean fit. Follow the manufacturer’s instructions for joining method appropriate to the metal system in use (for example press-fit, soldering or threaded coupling if applicable). Insert the 22 mm pipe into the reduced end and the 42 mm pipe into the larger end, ensuring proper alignment and engagement depth. Apply the recommended sealing method or compound where required and verify the connection for leaks after system pressurisation and during the first run.
Usage recommendations
Use the reducing nipple in systems designed for metallic pipe fittings and ensure compatibility with the chosen joining technique and operating temperatures/pressures. Perform pressure and leak tests after installation and observe applicable local regulations and standards for heating and refrigeration systems.
