1 inch x 18 inch Galvanized Steel Nipple

1" x 18" Galvanized Steel Nipple – Threaded Pipe Extension for Pressure Systems

The 1" x 18" Galvanized Steel Nipple is a threaded pipe section designed for joining and extending galvanized piping in a range of fluid and air distribution systems. Its hot-dip galvanized coating provides an added layer of protection against corrosion, making it suitable for use in non-potable water, compressed air, and outdoor installations.

This fitting meets dimensional tolerances for NPT threads, allowing for consistent sealing when used with compatible threaded steel or iron components. Its 18-inch length makes it ideal for bridging pipe gaps or offsetting equipment alignments in linear system layouts.

Key Functional Benefits

• ✅ Hot-Dip Galvanized Coating – Inhibits rust formation and enhances service life in exposed or moist environments.
• ✅ Machined NPT Threads – Provides reliable engagement and sealing with standard pipe fittings.
• ✅ All-Steel Construction – Suitable for high-load and moderate-pressure system configurations.
• ✅ Standard Taper Thread Profile – Designed for mechanical joint integrity without welding.

Installation Considerations

This component is intended for rigid pipe assemblies where threaded fittings are required. Use of PTFE tape or anaerobic thread sealant is recommended for achieving leak-resistant connections. Tightening torque should follow pipe material guidelines to prevent thread distortion or joint failure.

Technical Specifications

• Material: Schedule 40 galvanized steel
• Nominal Size: 1 inch
• Overall Length: 18 inches
• Thread Type: Male NPT, both ends
• Coating Process: Hot-dip galvanization
• Standards: Threads conform to ANSI/ASME B1.20.1

Common Applications

This nipple is used in mechanical room piping, air compressor lines, irrigation systems, and structural piping layouts. Its length and corrosion-resistant finish make it appropriate for both temporary setups and permanent infrastructure in industrial or outdoor environments.

Code Compliance Advisory

Galvanized steel pipe nipples are not intended for use in potable water systems. For systems requiring lead-free or NSF-listed materials, alternative brass or stainless steel fittings should be used.
