Brass Straight Union 3/4" FERRO SGU3 — plumbing fitting, male threads

FERRO SGU3 is a brass straight union with a 3/4" nominal size designed for reliable plumbing connections. The fitting provides a straight coupling between male threaded pipes or components and is made from corrosion-resistant brass suitable for water installations and general plumbing repairs. Its straightforward design supports secure joins between valves, hoses and copper or brass pipe sections in residential and commercial systems.

Advantages

The brass construction offers good resistance to corrosion and scaling in potable water systems while maintaining mechanical strength. A straight union shape enables quick alignment and connection of threaded components without the need for soldering. The compact form factor makes it easy to install in confined spaces and to replace worn or leaking joints with minimal disassembly.

Suitable for

• Connecting 3/4" threaded pipes and fittings in water supply lines
• Joining valves, flexible hoses and fixed pipe sections
• Repair and maintenance tasks in residential plumbing systems
• Commercial installations where brass fittings are required

Key specifications

• Material: brass, corrosion-resistant for typical water service
• Type: straight union for male threaded connections
• Nominal size: 3/4"
• Connection: threaded coupling designed for standard plumbing threads
• Application: cold and hot water systems, general plumbing repairs

How to use

Ensure pipe ends and mating threads are clean and free of debris or old sealant. Wrap appropriate thread sealant or tape on the male threads if required by the installation standards. Align the straight union with the mating component and hand-start the threads to avoid cross-threading, then tighten to a firm fit using a suitable wrench. Do not overtighten; follow torque guidelines for the installed piping material to avoid deformation of the fitting.

Usage recommendations

Use approved thread sealant compatible with drinking water when installing in potable water systems. Inspect the fitting periodically for signs of wear, corrosion or leaks and replace if necessary. For installations under pressure or in critical systems, verify compatibility of brass with the fluid and operating temperatures.
