Conex bypass single-socket connector B Press 18 mm P508601800000

The Conex bypass single-socket connector B Press 18 mm P508601800000 is a press-fit plumbing fitting designed for use with 18 mm copper or compatible tubing. It provides a single-socket (one-cup) bypass connection that allows flow to be diverted or looped without interrupting the primary line. The fitting is part of the B Press range and is intended for potable water and heating systems where press-style installation is specified. Its compact design enables installation in confined spaces and integration into distribution runs or service loops.

Advantages

This bypass connector offers a reliable press-fit connection that reduces the need for flame or soldering during installation, improving on-site safety and installation speed. The one-socket design simplifies assembly when a bypass or return loop is required, and compatibility with standard 18 mm tubing ensures straightforward replacement or retrofit. Materials and construction are selected for potable water and heating applications, providing corrosion resistance and long-term serviceability under normal operating conditions.

Suitable for

• Creating bypass loops in domestic and commercial potable water systems
• Establishing alternative flow paths in heating circuits and radiator connections
• Retrofit or repair where 18 mm press fittings are specified
• Compact installations requiring a single-socket bypass connection

Key specifications

• Connection type: single-socket press connection for press-fit installation
• Compatible tube diameter: 18 mm
• Application: potable water and heating systems
• Function: bypass/alternative flow path
• Installation method: press fitting (no soldering required)

How to use

Ensure the piping system is depressurised and drained before beginning work. Cut the 18 mm tubing squarely and remove any burrs or debris from the tube end. Insert the prepared tube fully into the connector socket until it bottoms, verifying correct tube seating. Use the appropriate press tool and jaw for 18 mm B Press fittings and perform the press operation according to the tool and fitting manufacturer's instructions. After pressing, inspect the joint visually and, where applicable, perform a pressure test of the system to confirm integrity.

Usage recommendations

Use with compatible 18 mm tubing materials approved for potable water or heating systems. Follow local plumbing codes and the press tool manufacturer's guidance. Avoid using the fitting in systems with media or temperatures outside the manufacturer's specified limits, and ensure routine inspection after installation where required.
