SANHA press reducing nipple 28 x 22 mm, model 162432822

SANHA press reducing nipple 28 x 22 mm, model 162432822 is a press-fit reducing connection designed to join pipes or fittings of different diameters. Intended for use in building installations, this reducing nipple creates a permanent pressed joint when used with compatible press tools and press rings. The component is suitable for potable water, heating and many industrial piping systems where a reliable reduction from 28 mm to 22 mm is required.

Advantages

The press reducing nipple provides a secure, gas- and watertight connection without the need for soldering or threaded joints, reducing installation time. Its design ensures consistent press geometry for reliable mechanical strength and leak resistance when used with the recommended pressing system. The compact form factor allows installation in confined spaces where a diameter change is necessary. Compatibility with standard press tools and rings simplifies inventory and tool requirements on site.

Suitable for

• Potable water distribution systems
• Heating systems including radiators and underfloor heating
• Industrial piping installations requiring diameter reduction
• Retrofit and repair work where two different pipe sizes must be joined

Key specifications

• Connection type: press-fit reducing nipple
• Nominal sizes: 28 mm reduced to 22 mm
• Material: manufactured to industry-standard metal material for press fittings
• Suitable media: potable water, heating fluids, compatible industrial media
• Installation method: press connection using compatible pressing tools and rings
• Application environments: residential, commercial and industrial piping systems

How to use

Prepare the pipe ends by cutting square and deburring both the 28 mm and 22 mm pipes. Ensure pipes are clean and free of scale, oil or other contaminants. Insert the press reducing nipple fully into the pipe until the stop (if present) or required insertion depth is reached. Position the appropriate press ring or use an integrated press profile according to the press system instructions. Operate a compatible press tool with the correct jaw/profile for 28 mm and 22 mm connections to complete the pressing process. After pressing, visually inspect the joints and, where applicable, perform a pressure test to confirm leak-tightness before putting the system into service.

Usage recommendations

Use only approved press tools and matching press rings for the specific press system to ensure certified joint performance. Always follow local regulations and manufacturer instructions for installation, testing and maintenance. For potable water installations, verify material suitability for drinking water standards in your region.
