1-1/4 inch x 60 inch Galvanized Steel Nipple

1-1/4" x 60" Galvanized Steel Nipple – Threaded Pipe Extension for Pressure and Utility Systems

The 1-1/4" x 60" Galvanized Steel Nipple is a schedule-rated fitting used for extending pipe runs or joining female-threaded components in fluid conveyance systems. Manufactured from zinc-coated carbon steel pipe, this nipple offers corrosion resistance for use in air, water, and low-pressure steam lines, making it suitable for both interior and exterior applications.

Both ends are precision-machined with tapered male NPT threads to meet standard pipe fitting tolerances. The 60" length provides extended reach for equipment tie-ins, risers, or layout transitions in mechanical, commercial, and residential plumbing assemblies.

Key Attributes for Field Use

• ✅ Hot-Dip Galvanized Coating – Provides protection against oxidation and rust in humid or exposed environments.
• ✅ Schedule 40 Pipe Wall – Suitable for most non-critical pressure applications in water and utility piping systems.
• ✅ Threaded Ends – National Pipe Taper (NPT) threads ensure compatibility with standard fittings, valves, and system components.
• ✅ Full-Cut Length – 60-inch dimension ideal for long-span routing without additional couplings or unions.

Technical Specifications

• Material: Carbon Steel with Hot-Dip Galvanized Finish
• Nominal Size: 1-1/4 inch
• Overall Length: 60 inches
• Connection Type: Male NPT x Male NPT
• Wall Type: Schedule 40
• Standards: Conforms to ASTM A53 / A733; Threads per ANSI B1.20.1

Installation Considerations

Pipe dope or PTFE thread sealant should be applied to male threads prior to assembly to ensure a pressure-tight seal. Over-tightening may cause thread deformation or misalignment—follow torque recommendations based on pipe size and material. This nipple is not suitable for underground burial without additional protection or coating.

Typical Applications

Commonly used in water distribution, compressed air systems, mechanical room assemblies, and exposed plumbing installations. Also applicable in industrial utility runs and structural framing when galvanized pipe is specified for its corrosion resistance and strength.

Code and Usage Note

Galvanized steel nipples are not recommended for potable water systems in jurisdictions where dissimilar metal interaction or lead leaching concerns are regulated. Always verify material compatibility and code acceptance prior to installation.
