2 inch x 48 inch Galvanized Steel Nipple

2" x 48" Galvanized Steel Nipple – Schedule 40, Threaded Both Ends

The 2" x 48" Galvanized Steel Nipple is a Schedule 40 straight pipe fitting used to extend, connect, or transition between two female-threaded components in mechanical and plumbing systems. Constructed from carbon steel and hot-dip galvanized to ASTM A123/A153 standards, this nipple is designed to provide durable, corrosion-resistant performance in non-potable water, air, oil, and other approved fluid applications.

Threaded on both ends per ANSI B1.20.1 (NPT), this fitting enables secure mechanical joints in systems subject to moderate pressure and temperature variations. Galvanized coating extends service life by resisting rust and environmental degradation in exposed or damp conditions.

Technical Specifications

• Material: Carbon steel with hot-dip galvanized finish
• Nominal Pipe Size: 2 inches
• Length: 48 inches (end-to-end)
• Connection Type: NPT male x NPT male
• Wall Thickness: Schedule 40
• Standards: ASTM A733 (nipple fabrication), ASTM A53 Grade A/B (pipe), ANSI B1.20.1 (threads)

Application Scope

This galvanized steel nipple is intended for use in threaded pipe systems that require corrosion resistance and structural integrity. Common installation areas include:

• ✅ Water distribution in non-potable systems
• ✅ Compressed air and pneumatic lines
• ✅ Outdoor irrigation and washdown infrastructure
• ✅ Low-pressure industrial fluid transfer
• ✅ Support extensions in pipe hangers and structural conduit routing

Installation Considerations

Install using pipe wrenches and apply an appropriate thread sealant (PTFE tape or pipe joint compound) to achieve a pressure-tight seal. Ensure that threads are clean, properly aligned, and fully engaged. Do not overtighten, as excessive torque can deform threads or cause joint failure. This nipple is not intended for pressurized potable water unless certified for such use.

Key Performance Features

• ✅ Hot-Dip Galvanized Coating: Protects steel substrate from corrosion in moisture-prone environments
• ✅ Long-Length Format: Provides extended reach without the need for multiple fittings or unions
• ✅ Threaded Ends: NPT threading ensures compatibility with standard pipe fittings
• ✅ High Mechanical Strength: Carbon steel body supports system loads and pressure requirements

Code & Compliance Note

This product is manufactured in accordance with applicable ASTM and ASME standards for non-potable water and mechanical piping systems. It should be installed in compliance with local plumbing and mechanical codes. For systems requiring NSF 61/372 certification, verify component approval with the project specifications or AHJ.

The 2" x 48" Galvanized Steel Nipple delivers durable, long-length connectivity for industrial, mechanical, and commercial-grade piping systems. Its corrosion-resistant coating and precise threading make it a dependable solution for pipe extension and system integration across a range of applications.
