Straight Connector Conex 302 15 x 1/2" brass

The Conex Straight Connector 302 in brass is a compact plumbing fitting designed to join a 15 mm pipe or fitting to a component with a 1/2" threaded connection. Manufactured in brass for corrosion resistance and mechanical strength, this straight connector enables transitions between metric and imperial thread standards without adapting the pipe layout. Suitable for domestic and light commercial installations, the connector supports water distribution, heating circuits and general plumbing joins where a reliable, fixed connection is required.

Advantages

Constructed from brass, the connector offers good resistance to corrosion and mechanical wear, ensuring long service life in water and heating applications. Its straight design provides a direct, low-profile joint that minimises flow disruption and simplifies alignment. The part is suitable for use where a metric 15 mm pipe must be connected to a 1/2" threaded fitting, allowing installers to combine different standards without additional adapters.

Suitable for

• Joining 15 mm copper or compatible metric tubing to 1/2" threaded fittings
• Domestic water distribution and plumbing repairs
• Connections in heating systems such as radiators and boilers
• Retrofit projects that require metric-to-imperial transitions

Key specifications

• Material: brass
• Connection types: 15 mm metric to 1/2" threaded
• Shape: straight connector
• Typical applications: water and heating systems, plumbing joins

How to use

Prepare the 15 mm pipe by cutting squarely and removing burrs. Ensure the 1/2" threaded component has clean threads and apply appropriate thread sealant or tape if required by the application. Slide the connector onto the prepared 15 mm pipe and tighten the 1/2" threaded end into the mating fitting using suitable wrenches. Observe recommended torque limits for fittings and verify that the joint is leak-free before putting the system into service.

Usage recommendations

Inspect joints after installation and periodically during the first days of operation to confirm there are no leaks. Use compatible pipe materials (such as copper or plastic with appropriate inserts) and correct sealing methods for threaded connections. Avoid excessive torque to prevent thread or fitting damage.
