## Long description

Conex reducing coupling 5000 series 28 x 18 mm is a copper press fitting designed to join two pipes of different diameters in water and heating systems. The compact reducing coupling provides a secure, solder-free transition from a 28 mm pipe to an 18 mm pipe using standard press-connection tools and rings. Manufactured in copper for compatibility with common plumbing materials, this fitting is intended for use in residential and commercial installations where a dependable diameter reduction is required.
Advantages
The reducing coupling offers a durable copper construction that resists corrosion and is compatible with standard press connection systems. Its press-fit design enables fast installation without soldering or threaded joints, reducing heat exposure and installation time. The compact form factor saves space in confined installations while ensuring a leak-resistant joint when installed with the correct press tooling and seals.

Key specifications
 Material: Copper
 Series: 5000 series reducing coupling
 Connection type: Press-fit
 Dimensions: 28 mm to 18 mm diameter reduction

How to use
Prepare the pipe ends by cutting square and removing burrs and debris.

Perform the press operation with the appropriate jaws to obtain a permanent, leak-resistant connection. After pressing, inspect the joint visually and, where required, perform a pressure test in line with local plumbing standards.
Usage recommendations
Use the reducing coupling with compatible press fittings, seals, and press tools specified for the 5000 series. Confirm material compatibility with existing piping and follow applicable codes for potable water and heating systems. Store fittings in a dry environment to avoid contamination before installation.
