Pipe reducer GEBERIT Mapress C-Steel 54 x 35 mm, model 22323

GEBERIT Mapress C-Steel pipe reducer 54 x 35 mm model 22323 is a press-fit fitting for connecting pipes of different diameters in C-steel installations. It provides a reliable transition from a 54 mm line to a 35 mm line using the Mapress press-connection system. The fitting is intended for use with water and non-aggressive media in heating, potable water and service lines where a secure, permanent metal connection is required.

Advantages

The Mapress C-Steel reducer is made of carbon steel compatible with Mapress press tools and jaws, ensuring consistent press connections and minimal installation time. Its design offers tight metal-to-metal joints without the need for soldering or welding, reducing labour and fire risk on site. The fitting supports standard pressure and temperature ranges for typical building services and is suitable for repeated use of approved pressing equipment.

Suitable for

• Transitioning between 54 mm and 35 mm C-steel pipes in heating systems
• Potable water distribution where certified press fittings are specified
• Service lines and plant rooms requiring secure metal press connections
• Commercial and residential plumbing installations using Mapress systems

Key specifications

• Material: carbon (C) steel compatible with Mapress press technology
• Connection type: press-fit Mapress connection
• Nominal dimensions: reduction from 54 mm to 35 mm diameter
• Suitable media: water and non-aggressive fluids
• Typical applications: heating, potable water and service piping

How to use

Prepare the pipe ends by cutting square and removing burrs and dirt. Insert the pipe fully into the reducer until the correct stop position is reached. Use the approved Mapress pressing tool and the matching jaw for C-steel to perform a single, complete press cycle according to the tool manufacturer’s instructions. Verify each pressed joint visually and, where required by project standards, perform pressure testing of the system after installation.

Usage recommendations

Ensure compatibility of the pressing tool and jaws with C-steel Mapress fittings and follow local codes for potable water or heating systems. Avoid using the reducer with aggressive chemicals or media not specified as compatible. Store fittings in a dry environment to prevent surface corrosion prior to installation.
