## Summary description

SANHA-Therm reducing nipple ZWxZZ 54x42 is a pipe fitting by SANHA designed to join different nominal diameters. The reducer nipple transitions from 54 mm to 42 mm and is intended for hot-water heating and plumbing installations. It is used to connect pipes or components of differing sizes, enabling flow continuity in heating circuits, radiators, and domestic water systems.

## Long description

SANHA-Therm reducing nipple ZWxZZ 54x42 is a metal pipe fitting designed to connect two pipe ends of different nominal diameters in hot-water heating and plumbing systems. The fitting provides a reliable transition from 54 mm to 42 mm, allowing continuity of flow and mechanical connection between components such as radiators, valves and straight pipe runs. It is intended for use in closed heating circuits and domestic hot-water installations where a stepped reduction of pipe size is required.
Advantages
The SANHA reducing nipple is manufactured for compatibility with common copper and similar metallic piping used in heating and plumbing. Its stepped geometry ensures stable alignment and a tight joint when installed with suitable soldering, brazing, or compression connections. The design minimizes turbulence at the change of diameter and supports secure mechanical retention under typical operating temperatures and pressures found in hot-water heating systems.
Suitable for
 Transitioning between 54 mm and 42 mm pipework in heating circuits
 Connecting radiators, boiler connections and distribution manifolds with different diameters
 Domestic hot-water and central heating system repairs and modifications
Key specifications
 Material: corrosion-resistant metal suitable for heating and plumbing applications
 Connection type: stepped reducing nipple for permanent joints (soldering, brazing) or compatible mechanical joining methods
 Nominal diameters: inlet 54 mm → outlet 42 mm
 Intended use temperature range: compatible with hot-water heating system temperatures
 Application area: closed heating circuits and domestic hot-water installations
How to use
Select the appropriate joining method for the pipe material and system design (e.g., soldering, brazing or approved mechanical fittings). Prepare pipe ends by cleaning and deburring to ensure full contact with the reducing nipple. Fit the nipple so the larger end seats onto the 54 mm pipe and the smaller end onto the 42 mm pipe; apply the chosen joining technique according to manufacturer and industry best practices. After installation, pressure-test the circuit and inspect joints for leakage before returning the system to service.
Usage recommendations
Use compatible soldering or brazing alloys and fluxes approved for heating systems and ensure installation is performed by qualified personnel familiar with hot-water heating standards. Verify material compatibility with existing piping to prevent galvanic corrosion and follow local codes for pressure testing and system commissioning.
