## Long description

FERRO SGU1 is a brass straight union with an O-ring designed for connecting 3/8" threaded plumbing components. The fitting is made of brass to resist corrosion in water and heating installations and features an integrated elastomer O-ring that ensures a sealed mechanical joint without the need for additional sealants. Its compact, straight design facilitates inline connections in confined spaces and maintenance tasks.
Advantages
The brass construction provides good corrosion resistance and mechanical strength for sustained use in domestic and commercial plumbing. The integrated O-ring creates a reliable seal that reduces the risk of leaks and simplifies assembly and disassembly. The union’s straight, compact form factor allows for easy installation in tight or recessed areas and is compatible with standard 3/8" threaded components, making it versatile for various repair and installation tasks.
Suitable for
Connecting 3/8" threaded water supply lines
Joining components in heating systems and radiators
Repair and replacement of valves, faucets and fittings
Compact inline connections in tight or concealed installations
Key specifications
Material: brass
Connection type: straight union with external/internal 3/8" threads
Seal: integrated elastomer O-ring
Application: potable water and heating systems
Design: compact straight coupling for inline connections
How to use
Ensure mating threads are clean and free of debris before assembly. Hand-start the union on the corresponding 3/8" threaded component to avoid cross-threading, then tighten to a secure fit using appropriate tools; avoid excessive torque to prevent damage to threads or the O-ring. If disassembly is required, loosen the union, inspect the O-ring for wear, and replace the O-ring if it shows signs of deformation or damage. Reassemble by aligning threads and tightening to a leak-free fit.
Usage recommendations
Use with compatible 3/8" threaded fittings and avoid using sealants that may degrade the O-ring material. Inspect the O-ring periodically in systems subject to thermal cycling or chemical exposure, and replace the fitting or O-ring if corrosion or seal wear is observed.
