Conex reducing connector 5000 series 28 x 22 mm

The Conex reducing connector 5000 series 28 x 22 mm is a mechanical coupling designed to provide a sealed transition between 28 mm and 22 mm pipework. It is intended for use where a reduction in pipe diameter is required in plumbing installations, heating systems and general maintenance applications. The connector is compatible with metal or plastic pipes of the specified outer diameters and provides a stable, leak-resistant joint when installed according to standard plumbing practice.

Advantages

The reducing connector offers a compact solution for changing pipe diameters without the need for soldering or complex fittings. Its design supports reliable sealing under typical domestic and commercial water and heating system pressures. The connector enables quick installation and reduces downtime during maintenance or system modification.

Suitable for

• Domestic and commercial plumbing repairs and installations
• Central heating and radiator connections requiring diameter reduction
• Maintenance work where temporary or permanent pipe size transition is needed
• Retrofit projects connecting existing 28 mm piping to 22 mm runs

Key specifications

• Compatible pipe outer diameters: 28 mm to 22 mm
• Series: 5000 series reducing connector
• Type: mechanical reducing coupling
• Suitable for use with compatible metal and plastic piping materials
• Intended application: plumbing and heating systems

How to use

Prepare pipe ends by ensuring they are clean, cut square and free from burrs or debris. Slide the connector onto the larger-diameter pipe, then align and insert the smaller-diameter pipe into the opposite end until the joint is fully engaged. Follow manufacturer guidance or standard plumbing practice for securing the connector, including any required tightening, clamping or sealing steps. After installation, pressurize the system and check the joint for leaks before returning the system to normal use.

Usage recommendations

Use the connector only with pipes that match the specified outer diameters and are compatible with the connector materials. Verify system pressure ratings and compatibility with the fluid being conveyed. For installations in concealed or critical locations, consider inspection access and follow applicable plumbing codes. When in doubt, consult a qualified installer.
