Conex straight connector CONEX 301 15x15 mm

Conex straight connector CONEX 301 15x15 mm is a compact inline coupling designed to join 15 mm copper or compatible plumbing tubing. The fitting provides a direct straight connection that maintains pipe alignment and internal bore continuity for water, heating and compatible gas distribution systems. Its nominal 15x15 mm dimensions make it suitable where two identical pipe sections must be joined with minimal profile and predictable hydraulic performance.

Advantages

This straight connector offers a simple, space-saving solution for creating a reliable joint between two 15 mm tubes without changing flow direction. It is manufactured to deliver consistent internal diameter alignment and a secure mechanical fit suitable for repair, retrofit and new installation work. The compact design reduces the need for additional fittings and keeps installation neat in confined spaces.

Suitable for

• Repair and replacement of short sections of 15 mm copper pipe
• Retrofit installations in domestic water and heating systems
• New build plumbing and central heating pipe runs using 15 mm tubing
• Inline coupling where minimal external profile is required

Key specifications

• Nominal size: 15 x 15 mm
• Type: straight inline connector
• Material compatibility: copper and compatible plumbing tubing
• Application: water, heating, and compatible gas distribution systems
• Design: compact, low-profile straight coupling

How to use

Prepare both pipe ends by cutting square and removing burrs or any debris to ensure proper seating. Slide the connector onto one pipe end and then onto the opposing pipe while maintaining alignment. Follow the manufacturer's recommended joining method for the specific Conex fitting type in use (for example, soldering, brazing, press-fit or compression, depending on the actual variant). Verify the joint for correct mechanical engagement and perform a pressure or leak test appropriate to the installed system before returning it to service.

Usage recommendations

Use this 15x15 mm straight connector in installations that require a low-profile, reliable inline joint. Ensure that tube material and the chosen joining method are compatible and compliant with applicable local codes and system operating pressures. For gas applications, verify certification and suitability for gas use and follow all safety requirements during installation and testing.
