Conex transitional male/female connector GZ B OYSTER 18 x 3/4" brass - Y8243G01806000

Conex transitional male/female connector GZ B OYSTER 18 x 3/4" brass is a brass joining fitting designed to connect 18 mm copper or plastic pipes to components with a 3/4" female thread. The fitting provides a threaded transition between pipework and threaded valves, appliances or couplings, enabling secure mechanical and hydraulic connection in plumbing systems. Constructed from brass, the connector resists corrosion and provides the mechanical strength required for standard domestic and light commercial installations.

Advantages

The brass construction offers durability and corrosion resistance for water systems. The transitional design simplifies adapting 18 mm copper or plastic pipework to 3/4" female threaded components without modifying existing piping. The male/female configuration ensures a straightforward threaded interface for reliable sealing when used with appropriate sealing materials or tape. The compact form factor supports installation in confined spaces common in repair and extension tasks.

Suitable for

• Connecting 18 mm copper or plastic pipe to 3/4" female threaded valves and fittings
• Plumbing repair and maintenance work
• System extensions where a threaded transition is required
• Domestic and light commercial water supply installations

Key specifications

• Material: brass
• Pipe connection size: 18 mm
• Threaded connection: 3/4" female thread interface (connector is male on the thread side)
• Type: transitional male/female joining connector
• Typical use: potable water and general plumbing systems

How to use

Prepare the 18 mm copper or plastic pipe by cutting square and deburring the end. Insert or attach the pipe according to the pipe material and joint method appropriate for the fitting (for example push-fit, soldering or compression—follow the compatible method for this specific connector). Apply appropriate thread sealant or PTFE tape to the male thread before engaging with a 3/4" female threaded component. Tighten the threaded connection to a suitable torque by hand and finish with a wrench to ensure a secure, leak-free joint, taking care not to overtighten which can damage threads or the connector.

Usage recommendations

Use suitable sealing materials on the threaded joint and check compatibility of the connector with the pipe material and system fluid. For installations carrying potable water, follow local plumbing codes and regulations and, if required, use approved installation methods and tools. Inspect the assembled connection for leaks after pressure testing and retighten if necessary following manufacturer's torque guidance where available.
