Copper press coupling Conex B Press 28 mm P527002800000 for plumbing connections

Copper press coupling Conex B Press 28 mm is a plumbing connector designed for joining 28 mm copper pipes using a press-fit method. Manufactured from copper, the coupling delivers a durable, solder-free joint suitable for potable water and heating systems. The design is intended to provide a reliable, leak-resistant connection that can be installed with a compatible pressing tool, reducing the need for open-flame soldering and speeding up installation times in both new builds and repair projects.

Advantages

The coupling’s copper construction ensures corrosion resistance and long-term stability in typical plumbing environments. Press-fit installation eliminates the need for soldering, flux or torches, improving on-site safety and enabling faster assembly. The coupling forms a permanent mechanical seal when pressed correctly, providing consistent performance for pressure-bearing water and heating circuits. Its compact dimensions allow use in confined spaces where traditional joining methods may be difficult.

Suitable for

• Joining 28 mm copper pipes in domestic and commercial water supply systems
• Connections in central heating and radiator installations
• Repair and renovation work where quick, reliable joints are required
• Situations where solder-free, flame-free installation is preferred

Key specifications

• Material: copper
• Connection method: press-fit
• Pipe compatibility: 28 mm copper pipe
• Application: potable water and heating systems
• Operating environment: indoor plumbing and heating installations

How to use

Prepare pipe ends by cutting square and deburring internal and external edges to ensure a clean fit. Ensure pipes are free from dirt, grease and deformation. Slide the coupling onto the pipe ends so the fitting is fully seated and properly aligned. Use a compatible pressing tool with the correct jaw profile to perform the press operation according to the tool and fitting manufacturer instructions. After pressing, inspect the joint visually to confirm the press mark or indicator is correct and perform pressure testing of the system as required by local regulations.

Usage recommendations

Use only approved pressing tools and jaws compatible with Conex B Press fittings, follow manufacturer guidelines for press depth and sequence, and conduct pressure testing before putting the system into service. Store fittings in a dry environment to avoid surface contamination prior to installation.
