Straight connector Conex 15 x 1/2" brass (Conex E031020303--)

The Conex straight connector in brass with dimensions 15 x 1/2" is a plumbing coupling designed to join a 15 mm pipe to a 1/2" threaded fitting. Manufactured in brass, the connector provides a stable metal joint suitable for domestic and light commercial water installations. The component is intended for inline connections where a change in pipe size or thread type is required, offering corrosion-resistant performance and mechanical strength typical of brass fittings.

Advantages

This brass straight connector offers reliable sealing and mechanical stability in potable water and heating systems. Its brass construction resists corrosion and provides good dimensional stability under normal operating temperatures and pressures. The connector enables a direct transition between metric and imperial plumbing sizes without the need for adapters that add bulk or complexity to the installation.

Suitable for

• Domestic water supply repair and replacement
• Connecting 15 mm copper or PEX pipe to 1/2" threaded valves or fixtures
• Small commercial plumbing installations and service work
• Inline coupling where space and a straight connection are required

Key specifications

• Material: brass
• Connection types: 15 mm pipe end to 1/2" threaded end
• Orientation: straight inline connector
• Typical application: water supply and heating systems
• Suitable for potable water use (where local regulations allow)

How to use

Prepare both mating pipe and threaded fitting by ensuring surfaces are clean and free of debris. For copper or PEX pipe, cut squarely and deburr the end before insertion; for threaded connections, apply appropriate thread sealant or PTFE tape according to local practice. Insert the pipe end fully into the connector or engage the threaded end and tighten to the required torque specified by the joining method. Verify alignment to avoid strain on the joint and perform a leak test after installation before returning the system to service.

Usage recommendations

Use compatible sealing materials and observe manufacturer or local plumbing codes for installation torque and testing. Avoid exposure to corrosive chemicals and excessive mechanical stress. If connecting different pipe materials, ensure appropriate transition fittings or liners are used where required.
