1/2 inch x 12 inch Galvanized Steel Nipple

1/2" x 12" Galvanized Steel Pipe Nipple – Threaded Schedule 40 Fitting for Low-Pressure Systems

The 1/2" x 12" Galvanized Steel Nipple is a Schedule 40 straight pipe segment with male NPT threads on both ends. Manufactured from welded carbon steel and hot-dip galvanized in accordance with ASTM A153, this fitting is designed for use in low- to moderate-pressure piping systems requiring corrosion resistance and dimensional consistency.

Its 12-inch length provides a prefabricated solution for extending or bridging pipe runs without field cutting. Commonly installed in water supply, air distribution, and hydronic heating systems, this nipple ensures compatibility with threaded galvanized or black fittings in both residential and commercial applications.

Key Features

• ✅ Schedule 40 Wall Thickness Complies with standard piping specifications for mechanical and plumbing systems.
• ✅ Male NPT Threads Threaded to ASME B1.20.1 standards for tight, leak-resistant sealing using pipe joint compound or PTFE tape.
• ✅ Hot-Dip Galvanized Coating Zinc finish resists rust and oxidation in non-submerged environments and provides added longevity in utility systems.
• ✅ Welded Steel Construction Fabricated to ASTM A733 and ASTM A53 standards for strength and structural reliability.

Technical Specifications

• Nominal Size: 1/2 inch
• Length: 12 inches
• Material: Carbon steel with hot-dip galvanized finish
• Thread Type: Male NPT x Male NPT
• Applicable Standards: ASTM A53, ASTM A733, ASTM A153, ASME B1.20.1
• Pressure Rating: Typically up to 150 PSI (non-shock cold water systems)

Installation Considerations

Ensure threads are clean before applying sealant. Use PTFE tape or pipe dope rated for galvanized connections. Align threads carefully to prevent cross-threading and tighten with a pipe wrench until the connection is secure. Over-tightening can distort threads or damage mating components. Pressure-test system per local code following installation.

Common Applications

Used in above-ground piping systems such as potable water lines, heating loops, and compressed air lines. The 12" length is ideal for long offsets, equipment connections, and riser extensions in both new construction and retrofit scenarios.

Material Note

Galvanized steel is intended for use in non-corrosive indoor environments. For continuous exposure to aggressive chemicals, buried service, or potable hot water in jurisdictions that restrict galvanized pipe, an alternative material such as stainless steel or brass may be required.

The 1/2" x 12" Galvanized Steel Pipe Nipple offers professional-grade performance and durability in threaded pipe systems. Manufactured to precise tolerances, it provides consistent results in general-purpose plumbing, mechanical, and industrial piping installations.
