Standard 3/4 Inch GI Hex Nipple, Galvanized Iron, Male Threaded

3/4 Inch GI Hex Nipple

The Standard 3/4 Inch GI Hex Nipple provides a heavy-duty solution for connecting female threaded pipe sections and fittings in high-pressure fluid systems. This galvanized iron component features precision-cut male threads at both ends, separated by a robust hexagonal center section. It ensures a rigid, leak-proof joint in residential, commercial, and agricultural water supply networks.

Built for the Job

Plumbers and facility managers rely on this fitting for extending pipe runs or installing valves within complex manifolds. The galvanized construction withstands the mechanical stress of high-torque tightening and the environmental demands of outdoor exposures. It serves as a critical link in irrigation systems, fire protection lines, and industrial water transport where plastic fittings lack the necessary burst strength or heat resistance. The 3/4 inch sizing matches standard commercial plumbing diameters, making it a staple item for site maintenance and new construction installations.

• Connecting two female-threaded gate valves or ball valves in a pump house manifold.

• Extending pipe outlets from walls to accommodate surface-mounted fixtures or industrial equipment.

• Adapting steel pipe runs within irrigation sub-mains to ensure secure fluid transition.

Product Highlights

Corrosion Resistance

The hot-dipped zinc coating provides a protective barrier that prevents oxidation and rust in damp environments.

High-Torque Hex Center

• The integrated hex nut allows for a firm grip with a standard pipe wrench or adjustable spanner.
• Prevents damage to the threads during installation by providing a dedicated tightening surface.

On-Site & Workshop Notes

• Apply high-quality PTFE thread sealant tape or pipe dope to the male threads to ensure a watertight seal.

• Avoid over-tightening the fitting into cast iron valves to prevent cracking the female housing.

• This metal connector is compatible with black steel and galvanized pipe but requires a dielectric union if connecting to copper systems.

• Clean any debris from the threads before engagement to prevent cross-threading or grit-induced leaks.
