Conex reducing coupling 5000 series 35 x 22 mm

Conex reducing coupling 5000 series 35 x 22 mm provides a compact mechanical connection to join a 35 mm pipe or tube to a 22 mm pipe or tube. Part of the Conex 5000 series, this coupling is designed for installations where a smaller downstream diameter is required, enabling a secure transition in potable water, heating circuits, and general plumbing repairs or retrofits. The product uses a push-fit/press-style mechanical connection intended to deliver a reliable sealed joint without the need for soldering or complex on-site preparation.

Advantages

The Conex reducing coupling allows quick assembly with minimal tools, reducing installation time. Its mechanical push-fit/press-style design creates a consistent, leak-resistant joint suitable for potable water and heating systems. The compact form factor makes it easy to install in confined spaces and during retrofit work where access is restricted. The coupling provides a durable transition between differing pipe diameters while eliminating the need for heat or flux.

Suitable for

• Reducing a 35 mm pipe run to 22 mm in potable water systems
• Downsizing connections in central heating or radiator circuits
• Repair and retrofit work where a compact transition is required
• Installations requiring a mechanical push-fit/press-style joint without soldering

Key specifications

• Connection type: mechanical push-fit / press-style
• Inlet diameter: 35 mm
• Outlet diameter: 22 mm
• Series: Conex 5000 series
• Application: potable water and heating circuits
• Form factor: compact reducing coupling for tight spaces

How to use

Prepare both pipe ends by ensuring they are cut square, clean and free from burrs and debris. Confirm compatibility with the intended pipe material and ensure the system is depressurised before fitting. Insert the 35 mm and 22 mm pipes fully into the respective ends of the coupling until they locate against the internal stops. If required by the installation method, complete the mechanical press operation using the appropriate pressing tool or follow the manufacturer’s push-fit engagement procedure to achieve the final sealed joint. After installation, restore system pressure and inspect the joint for leaks.

Usage recommendations

Use the coupling only with pipe materials and system types recommended for the Conex 5000 series and follow local plumbing regulations. For long-term reliability, verify that pressing tools are calibrated and that installation clearances allow full engagement. Perform a pressure test after fitting to confirm leak-free operation before commissioning the system.
