Adapter union Conex transitional connector GZ B OYSTER 15x1/2" brass

Conex transitional connector GZ B OYSTER 15x1/2" in brass is an adapter union designed to provide a secure threaded transition between 15 mm plumbing pipe connections and 1/2" male threads. Manufactured from brass for corrosion resistance and mechanical durability, this connector is intended for use where a reliable join is required between metric pipework and BSP-sized fittings in domestic and light commercial installations.

Advantages

The brass construction ensures good resistance to corrosion and long service life under normal plumbing conditions. The transitional geometry allows simple connection between 15 mm pipe systems and 1/2" male threaded components without the need for additional reducers or complex fittings. Its compact design minimises space requirements and simplifies installation in confined areas. Threaded ends provide a secure, leak-resistant joint when installed with the appropriate sealing method.

Suitable for

• Domestic plumbing repairs and upgrades
• Heating system connections and radiator installations
• Water distribution lines requiring metric-to-BSP transitions
• Connecting faucets, valves or meters with 1/2" male threads to 15 mm copper or plastic pipework

Key specifications

• Material: brass for corrosion resistance
• Connection types: 15 mm pipe side to 1/2" male threaded side
• Application: potable water, heating and general plumbing systems
• Design: compact adapter union suitable for confined spaces

How to use

Prepare the 15 mm pipe end by cutting square and deburring. Ensure the mating 1/2" male thread is clean and undamaged. Fit the adapter union onto the pipe and tighten the threaded connection to the 1/2" male thread using appropriate tools. Apply an appropriate sealing method to the threads (such as PTFE tape or approved thread sealant) according to local plumbing codes and component manufacturer guidance. After assembly, pressurise the system and check for leaks, then retighten connections if necessary to achieve a watertight joint.

Usage recommendations

Use compatible sealing materials and follow local regulations for potable water or heating installations. Avoid excessive torque on brass threads to prevent deformation. Inspect the connector periodically for signs of wear or corrosion in aggressive environments and replace if any compromise to the sealing surface is observed.
