Brass Straight Union with O-ring FERRO SGU1 3/8" fitting

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.
