## Long description

FERRO SG18 brass half-union 6/4x1" is a threaded plumbing fitting designed to connect pipes, valves and fixtures in heating and water supply systems. Manufactured from brass for corrosion resistance and lasting mechanical strength, the half-union allows quick assembly and disassembly of a joint without cutting the pipe. Its dimensions (6/4x1") match common domestic and commercial piping standards, making it suitable for repair, replacement or new installations where a reliable sealed connection is required.
Advantages
The brass construction provides good resistance to corrosion and scaling while maintaining dimensional stability under typical operating temperatures and pressures in domestic heating and water systems. The half-union design enables simple disconnection and reconnection of components, reducing service time during maintenance or replacement. Threaded ends ensure compatibility with standard fittings and valves, offering a secure mechanical seal when properly installed.
Suitable for
 Joining valves to pipework in residential and commercial heating systems
 Connecting fixtures and fittings in potable water installations
 Repairing or replacing sections of piping without soldering or gluing
 Temporary or permanent threaded connections in maintenance operations
Key specifications
 Material: brass for corrosion resistance
 Connection type: threaded half-union
 Size compatibility: 6/4x1" piping dimensions
 Application: heating and water supply systems
 Typical use environment: residential and commercial installations
How to use
Ensure mating threads on pipes and fittings are clean and free from debris or old sealant. Apply a suitable thread sealant or PTFE tape to the male threads according to local plumbing codes. Hand-tighten the half-union onto the mating component and complete assembly with a wrench to the required snugness without over-tightening. After installation, pressurize the system and inspect the joint for leaks; retighten slightly if necessary. For disassembly, isolate and depressurize the system before loosening the union and separating components.
Usage recommendations
Use appropriate thread sealant compatible with potable water where required. Do not exceed the operating temperature and pressure limits specified for the overall piping system. Periodically inspect threaded connections during routine maintenance and replace the half-union if signs of corrosion or mechanical damage appear.
