## Long description

The Conex series 5000 reducer coupling 22 x 18 mm is a metal plumbing fitting engineered to join two copper, brass or compatible material pipes with different outer diameters. It provides a compact, mechanically stable connection that adapts a 22 mm line to an 18 mm line for potable water and heating systems when installed according to applicable standards and with compatible materials. The coupling is intended for domestic and light commercial pipework where a reliable, leak-resistant transition between pipe sizes is required.
Advantages
The reducer coupling offers a secure, low-profile transition between 22 mm and 18 mm pipes with consistent inner alignment to minimise flow disruption. Manufactured to Conex quality criteria, the fitting delivers mechanical durability and predictable performance in standard plumbing applications. Its design simplifies replacement or resizing of sections of pipework without extensive rework and reduces the need for additional adapters or custom fittings.
Suitable for
Domestic potable water distribution where pipe size reduction is required
Central heating and radiator connections in residential and light commercial buildings
Repairs and modifications in existing copper or compatible metal pipe systems
Plumbing runs where a compact, permanent metal joint is preferred over temporary or plastic alternatives
Key specifications
Connection sizes: 22 mm to 18 mm
Material: metal suitable for standard plumbing use (copper/brass compatible)
Application: potable water and heating systems when installed with compatible materials
Type: reducer coupling for permanent pipe connection
How to use
Prepare the pipe ends by cutting square and removing burrs, corrosion or scale. Ensure both pipe surfaces are clean and compatible with the coupling material. Slide the fitting onto the larger or smaller pipe end as required and complete the joint using the approved method for the specific Conex series 5000 fitting (for example soldering, brazing or approved mechanical joining method). Follow local plumbing codes and the manufacturer’s installation instructions to ensure a watertight connection and adequate mechanical support.
Usage recommendations
Verify material compatibility and pressure/temperature ratings for your system before installation. Use appropriate jointing techniques specified for Conex series 5000 products, and test the completed installation for leaks under working pressure. For potable water systems, follow local drinking water regulations and flushing procedures after completing work.
