## Long description

SANHA-Therm reducing nipple ZWxZZ 42ax28 is a copper pipe fitting designed to join two pipes with different outer diameters, enabling a reliable step-down connection from 42 mm to 28 mm. Intended for use in plumbing and heating systems, the fitting is manufactured from copper to offer corrosion resistance and good thermal conductivity. It is suitable for installations where a permanent mechanical and fluid-tight joint is required and can be installed using common joining methods appropriate for copper fittings.
Advantages
The copper construction provides durability and resistance to corrosion while maintaining thermal efficiency in heating circuits. The reducing nipple delivers a compact and space-saving transition between two pipe sizes, reducing the need for additional adapters. Its geometry ensures a stable, concentric connection that supports reliable flow characteristics and minimizes turbulence at the reduction point.
Suitable for
 Domestic and commercial heating systems that require a step-down pipe transition
 Plumbing installations where different-diameter copper pipes must be joined
 Renovation projects replacing or adapting sections of existing copper piping
 Hydronic circuits and distribution manifolds with size changes
Key specifications
 Material: copper
 Connection type: reducing nipple for joining two outer diameters
 Nominal outer diameters: 42 mm to 28 mm
 Suitable for soldered or press-fit installation methods depending on the system
 Application: plumbing and heating systems
How to use
Select the reducing nipple sized 42 mm to 28 mm compatible with the copper pipes in your system. Prepare pipe ends by cutting square, deburring, and cleaning the surfaces to be joined. Install the fitting according to the chosen joining method: for soldered connections apply appropriate flux and solder with correct heating; for press-fit systems use the manufacturer-recommended pressing tool and procedure. After joining, verify alignment and ensure the joint is tight and leak-free before restoring system pressure or heating.
Usage recommendations
Use only pipes and joining materials compatible with copper and follow local plumbing codes. When using soldered joints, ensure proper ventilation and follow safe heating practices. For press-fit installation, use the recommended press jaws and check the tool maintenance to achieve a secure, permanent connection.
