1 inch x 3 inch Galvanized Steel Nipple

1” x 3” Galvanized Steel Nipple – Threaded Schedule 40 Connector

The 1” x 3” Galvanized Steel Nipple is a threaded pipe fitting used to extend pipe runs or connect two fittings of the same diameter in fluid and gas distribution systems. Manufactured from welded Schedule 40 steel pipe and hot-dip galvanized in accordance with ASTM A123, it provides corrosion resistance and mechanical strength suitable for general-purpose plumbing and mechanical systems.

This nipple is commonly employed in pressurized water lines, air systems, and non-potable utility applications where a durable, zinc-coated steel connector is required. Threading is NPT (National Pipe Thread) per ANSI/ASME B1.20.1, offering consistent and secure connections across standard pipe fittings.

Specifications

• Material: Welded Schedule 40 Carbon Steel
• Coating: Hot-Dip Galvanized per ASTM A123
• Nominal Pipe Size: 1 inch
• Length: 3 inches
• Thread Type: NPT, Male x Male
• Pressure Rating: Up to 150 PSI (dependent on system configuration and pipe type)

Applications

• • Low-pressure water distribution
• • Compressed air systems
• • Fire protection loop piping (not for sprinkler risers)
• • Irrigation and mechanical utility systems

Installation Notes

Install using a compatible female-threaded fitting and a suitable thread sealant or Teflon tape to ensure a watertight connection. Avoid overtightening, which may damage threads. Not suitable for potable water systems unless approved galvanized pipe and fittings are specified and certified accordingly.

Compliance

• Thread Standard: ANSI/ASME B1.20.1 (NPT)
• Material Standard: ASTM A53 or A106 (base pipe)
• Coating Standard: ASTM A123 (hot-dip galvanized)

Galvanized steel nipples are widely used in industrial and commercial piping systems for their structural integrity and corrosion resistance. The 1” x 3” configuration offers a practical solution for short pipe extensions and transitions between threaded components.
