1-1/4 inch x 72 inch Galvanized Steel Nipple

1-1/4” x 72” Galvanized Steel Nipple – Extended-Run Threaded Connector for Mechanical Piping

The 1-1/4” x 72” galvanized steel nipple is a long-length, threaded pipe fitting designed to connect sections of Schedule 40 piping where continuous linear runs are required. Manufactured from carbon steel and hot-dip galvanized in accordance with ASTM standards, this component provides mechanical durability and corrosion resistance for non-potable water, air, and low-pressure gas systems.

Equipped with male NPT threads on both ends, the nipple allows for direct coupling between female-threaded components without the need for welding or grooving. Its extended 6-foot length minimizes joint count, reducing installation time and potential leak points in long-span piping applications.

Key Technical Features

• ✅ Material: Hot-dip galvanized carbon steel for corrosion protection in exposed environments
• ✅ Nominal Pipe Size: 1-1/4 inch
• ✅ Overall Length: 72 inches (6 feet)
• ✅ Thread Type: Male NPT x Male NPT – machined to ANSI B1.20.1 standards
• ✅ Wall Thickness: Compliant with Schedule 40 pipe specifications

Installation Notes

Installers should apply a compatible thread sealant or PTFE tape to both threaded ends prior to assembly. Given the fitting’s length, mechanical support or bracing may be required to prevent deflection or loading at connection points. Torque should be applied evenly to maintain thread integrity and ensure a pressure-tight seal.

Typical Applications

The 1-1/4” x 72” galvanized nipple is commonly used in:

• Water distribution lines in non-potable service
• Low-pressure compressed air systems
• Mechanical room piping and long-run utility headers
• Industrial process piping in corrosion-prone settings

Material Considerations

Galvanized steel is not intended for use in potable water systems due to the potential for zinc leaching. However, it is well suited for general service and outdoor applications requiring structural integrity and corrosion resistance.

The 1-1/4” x 72” galvanized steel nipple provides a reliable, long-span connection option for extended mechanical runs, helping reduce fitting count and maintain piping system integrity. Its schedule-grade wall thickness and corrosion-resistant finish make it a durable component for commercial, industrial, and facility piping layouts.
