Copper press coupling Conex B Press 15 mm P527001500000 — plumbing connector

Copper press coupling Conex B Press 15 mm is a straight plumbing connector designed to join 15 mm copper pipes with a pressed joint. Intended for potable water and heating systems, the coupling provides a mechanical, solder-free connection that reduces installation time and the need for open flame. The compact design fits into tight spaces and is compatible with standard 15 mm copper tubing and press tools meeting industry specifications.

Advantages

The Conex B press coupling offers a durable, leak-resistant joint achieved by press-fit technology, eliminating the need for soldering and flux. Its copper construction ensures corrosion resistance and compatibility with potable water, while the press connection provides consistent mechanical strength and repeatable results. Installation is faster compared with traditional brazing or soldering methods, and the coupling is suitable for concealed and visible pipework without compromising joint integrity.

Suitable for

• Joining 15 mm copper pipe runs in domestic potable water systems
• Connecting copper pipe sections in central heating systems
• Repairs and retrofits where soldering is impractical or restricted
• Tight or confined spaces requiring compact connectors

Key specifications

• Material: copper
• Connection method: press-fit
• Nominal size: 15 mm
• Typical applications: potable water and heating systems
• Form factor: straight coupling for joining two pipes

How to use

Prepare the pipe ends by cutting square and deburring the inside and outside surfaces. Slide the coupling onto one pipe end, align the second pipe, and ensure both pipes are fully inserted to the required depth. Use a compatible press tool and appropriate jaw or ring sized for 15 mm copper fittings to actuate the press connection. Verify the press profile visually or with manufacturer-recommended inspection marks where present. After pressing, perform a pressure test in accordance with applicable plumbing standards to confirm a leak-free joint.

Usage recommendations

Use approved press tools and jaws sized for 15 mm copper fittings; follow local plumbing codes for potable water and heating installations. Avoid excessive mechanical stress on freshly pressed joints and conduct pressure testing after installation. For concealed installations, document joint locations and follow any manufacturer guidance on inspection intervals.
