Copper Press Coupling Conex B Series 18 mm (P527001800000)

The Conex B Series copper press coupling 18 mm is a mechanical fitting designed for joining 18 mm copper pipes with a press-fit installation method. It creates a permanent, leak-resistant joint without soldering, brazing or threaded connections. The coupling is intended for use in potable water, heating and general plumbing systems where press fittings are specified, enabling faster installation and reduced joint preparation compared with traditional soldered joints.

Advantages

This copper press coupling offers a robust, durable connection that resists leaks and provides consistent mechanical strength across installations. The press-fit design reduces installation time and removes the need for open flame or flux, improving site safety and simplifying compliance with hot-work restrictions. The coupling is compatible with standard 18 mm copper tubing and is suitable for use in confined spaces where access for soldering is limited.

Suitable for

• Domestic and commercial potable water distribution
• Central heating systems and radiator connections
• General plumbing repairs and retrofits where press fittings are preferred
• Installations requiring flame-free joining methods or fast assembly

Key specifications

• Material: copper
• Connection method: press-fit (mechanical crimping)
• Pipe diameter compatibility: 18 mm copper tubing
• Suitable media: potable water, heating fluids
• Typical application temperature range: compatible with domestic hot and cold water and heating system temperatures

How to use

Prepare pipe ends by cutting square and deburring the inner and outer edges. Mark insertion depth on the pipe if required by the press tool manufacturer. Slide the coupling over the pipe ends and ensure full insertion to the marked depth. Use a compatible press tool and correct jaw/profile for copper press fittings to perform the press operation according to the tool and fitting manufacturer's instructions. After pressing, visually inspect the joint and, where applicable, conduct pressure testing or system commissioning checks following applicable standards and regulations.

Usage recommendations

Use with compatible press tools and jaws specifically rated for copper press fittings. Store fittings in a dry environment and avoid damage to sealing surfaces before installation. Follow local plumbing codes and manufacturer instructions for pressure testing and system commissioning.
