1 inch x 12 inch Galvanized Steel Nipple

1" x 12" Galvanized Steel Nipple – Corrosion-Resistant Threaded Connector

The 1" x 12" Galvanized Steel Nipple is a straight-threaded pipe segment manufactured for use in pressurized mechanical systems. Made from welded or seamless steel pipe and hot-dip galvanized for enhanced corrosion resistance, this fitting is suitable for potable water systems, HVAC installations, and industrial fluid transfer where zinc coating is necessary to prevent rust.

Key Performance Features

• ✅ Hot-Dip Galvanized Coating: Provides a protective zinc barrier against corrosion, extending service life in humid or wet environments.
• ✅ Schedule 40 Wall Thickness: Ensures consistent pressure performance across standard applications.
• ✅ National Pipe Thread (NPT) Ends: Machined to ANSI B1.20.1 specifications for compatibility with female-threaded components.
• ✅ 12" Length: Offers reach and spacing in systems requiring extended runs between pipe fittings or valves.
• ✅ Full Bore Flow: Nominal bore design enables consistent flow with minimal restriction across connected pipework.

Material and Dimensional Specifications

• Material: Carbon steel pipe (ASTM A53 or equivalent)
• Finish: Hot-dip galvanized to ASTM A123/A153 standards
• Nominal Pipe Size: 1 inch
• Overall Length: 12 inches
• Ends: Threaded male x male (NPT)
• Wall Thickness: Schedule 40

Installation Considerations

This galvanized nipple is installed using pipe thread sealant or PTFE tape to ensure leak resistance. Avoid over-tightening during assembly to prevent thread deformation. Threaded joints should be torqued according to the size and material compatibility of the connecting components. Not recommended for use with systems carrying acids or highly corrosive materials, as these can degrade the zinc coating.

Typical Applications

Commonly used in:

• Potable water distribution lines
• Compressed air systems
• Outdoor hose bibbs and spigots
• Mechanical heating loops and manifolds
• General plumbing requiring corrosion-resistant threaded steel

Note on Galvanized Use

Galvanized steel pipe is suitable for potable water when certified lead-free and used in compliance with local plumbing codes. Its use in gas lines may be restricted depending on jurisdiction due to scale formation risks.

The 1" x 12" Galvanized Steel Nipple offers reliable service in moderate-pressure environments requiring threaded steel piping with corrosion protection. Built for mechanical durability and field reliability, it remains a standard choice for commercial, residential, and light industrial systems where material longevity and fitment integrity are critical.
