1-1/4 inch x 36 inch Galvanized Steel Nipple

1-1/4" x 36" Galvanized Steel Nipple – Schedule 40 Threaded Pipe for Utility Piping Systems

The 1-1/4" x 36" Galvanized Steel Nipple is a Schedule 40 threaded pipe segment used for extending or connecting sections of galvanized steel piping. Manufactured from carbon steel and coated through a hot-dip galvanizing process, this nipple provides enhanced corrosion resistance and structural strength in both above-ground and buried installations.

This component features male National Pipe Thread (NPT) ends on both sides, allowing integration into existing threaded piping systems. Its 36-inch length is particularly useful in long straight runs or offsets where rigid connections are required without welding or coupling multiple fittings.

Functional Specifications

• ✅ Material: Carbon steel with hot-dip galvanized finish for corrosion resistance in moisture-prone or exposed environments.
• ✅ Connection Type: Threaded NPT on both ends for compatibility with galvanized or black malleable iron fittings.
• ✅ Nominal Pipe Size: 1-1/4 inch
• ✅ Length: 36 inches overall
• ✅ Wall Thickness: Conforms to Schedule 40 pipe dimensions
• ✅ Standards: Threads comply with ANSI/ASME B1.20.1; pipe manufactured to ASTM A53 or A106 standards (as applicable)

Installation and Use

Used for rigid pipe runs in plumbing, mechanical, and industrial applications. Threaded ends require proper sealing with PTFE tape or thread compound to ensure leak-tight joints. Suitable for cold water supply lines, air distribution, and structural piping where corrosion resistance is essential.

Applications

Typical use includes water supply systems, pump assemblies, HVAC loop piping, and equipment connections in residential, commercial, and light industrial settings. Can also be employed in low-pressure steam and compressed air systems when appropriately rated.

Installation Considerations

All threaded connections should be installed using appropriate torque to avoid thread galling or fitting distortion. Avoid exposure to acidic or highly alkaline substances that may degrade the zinc coating. Pipe supports should be placed to minimize sagging over long spans.
