Copper reducing nipple SANHA 5243 28 x 22 mm (copper pipe fitting)

Copper reducing nipple SANHA 5243 28 x 22 mm is a cylindrical copper pipe fitting designed to connect two copper pipes of different diameters. It provides a smooth transition from a 28 mm line to a 22 mm line, intended for use in plumbing and heating systems where a reliable, corrosion-resistant copper connection is required. The fitting is manufactured by SANHA and is suitable for soldered or pressed copper installations depending on the system requirements and local installation practices.

Advantages

The SANHA 5243 reducing nipple offers a compact, single-piece solution for diameter reduction with copper's natural corrosion resistance and thermal conductivity. Its solid copper construction ensures consistent mechanical strength and compatibility with copper piping materials. The simple cylindrical design facilitates straightforward alignment and installation with minimal joint complexity, reducing potential leak points when correctly joined.

Suitable for

• Domestic and commercial potable water supply lines
• Heating circuits and radiator connections
• Retrofit work where existing 28 mm piping must be reduced to 22 mm
• General copper plumbing in residential buildings

Key specifications

• Material: copper
• Type: reducing nipple (cylindrical)
• Connection sizes: 28 mm to 22 mm
• Application: plumbing and heating systems
• Corrosion resistance: inherent to copper material

How to use

Prepare both copper pipe ends by cutting square and deburring the inner and outer edges to ensure a proper fit. Slide the nipple into the prepared pipe ends and align the pipes for a straight joint. Complete the joint according to the chosen joining method — for soldering, apply flux and uniformly heat the joint area before applying appropriate solder; for press or mechanical joining, follow the press fitting manufacturer's instructions and use the correct press tool and jaw for copper fittings. After joining, verify the connection visually and perform a pressure test in accordance with local codes and project requirements.

Usage recommendations

Use compatible joining methods and consumables rated for copper. Observe local regulations and standards for potable water and heating installations, and ensure joints are pressure-tested before placing the system into service.
