1-1/4 inch x 2 inch Galvanized Steel Nipple

1-1/4" x 2" Galvanized Steel Pipe Nipple – Schedule 40, Threaded M x M

The 1-1/4" x 2" Galvanized Steel Nipple is a short-length, Schedule 40 threaded pipe segment used for joining female-threaded fittings or extending pipe runs in water, air, or mechanical systems. This component is manufactured from welded steel pipe with a hot-dip galvanized zinc coating for enhanced corrosion resistance, particularly in outdoor or humid environments.

Threaded on both ends per ANSI B1.20.1 NPT standards, this nipple allows for quick and secure connection of system components. It is suitable for low- to moderate-pressure applications, such as irrigation, non-potable water distribution, air compressor lines, and general utility piping where galvanic corrosion protection is desired.

Professional Use Features

• ✅ Material: Carbon steel pipe with hot-dip galvanized coating (zinc applied per ASTM A123 or A153)
• ✅ Thread Type: Male National Pipe Thread (NPT) x Male NPT
• ✅ Nominal Size: 1-1/4" diameter x 2" overall length
• ✅ Pressure Rating: Suitable for 150 PSI non-shock working pressure (dependent on system design and temperature)
• ✅ Threaded Ends: Precision-machined for reliable sealing with compatible female NPT fittings

Technical Standards

• Conforms to: ASTM A53 (Type E or S), ANSI B1.20.1 (threading)
• Wall Thickness: Schedule 40 (standard weight)
• Finish: Galvanized (interior and exterior zinc coating)

Typical Applications

This fitting is commonly used in water supply, process piping, compressed air systems, and fire protection risers where a short male-to-male connection is required. Also used in mechanical rooms, agricultural irrigation systems, and site utilities where exposure to moisture necessitates galvanized protection.

Installation Notes

Use with approved PTFE tape or pipe thread compound on male threads to ensure leak-tight joints. Tighten using standard pipe wrenches. Avoid over-torqueing to prevent thread distortion. This fitting is not rated for potable water in jurisdictions where galvanized steel is restricted for such use—verify with local plumbing codes.

The 1-1/4" x 2" Galvanized Steel Pipe Nipple delivers structural durability and corrosion resistance in threaded steel piping systems. Engineered for commercial and industrial use, it ensures secure, code-aligned connectivity across a variety of field conditions.
