2 inch x 3-1/2 inch Galvanized Steel Nipple

2" x 3-1/2" Galvanized Steel Nipple – Threaded Pipe Segment for Corrosion-Resistant Utility Systems

The 2" x 3-1/2" galvanized steel nipple is a Schedule 40 pipe segment with male NPT threads at both ends. It is fabricated from carbon steel pipe and hot-dip galvanized to ASTM A153 standards to enhance corrosion resistance in water distribution and general-purpose piping systems. This fitting is used for inline connections where rigid, threaded joints are required in mechanical, commercial, or light industrial applications.

Technical Specifications

• Nominal Size: 2 inch
• Length: 3-1/2 inches overall
• Material: Carbon steel, Schedule 40
• Finish: Hot-dip galvanized coating per ASTM A153
• Thread Type: NPT (National Pipe Taper), per ANSI/ASME B1.20.1
• Manufacturing Standard: ASTM A733 (pipe nipple spec), pipe to ASTM A53 Grade A/B
• Application: Non-potable water systems, air lines, industrial drainage, and mechanical utility piping

Installation Notes

Use PTFE thread sealant or compatible pipe joint compound on all male threads. Tighten using a pipe wrench sized appropriately for 2" diameter fittings. Avoid overtightening to maintain thread integrity. Suitable for use in above-ground installations or in enclosures where exposure to moisture is controlled.

Common Applications

Typical uses include:

• Cold water distribution in non-potable systems
• Mechanical piping assemblies and equipment connections
• Irrigation and outdoor utility lines (with appropriate protection)
• Air and low-pressure fluid conveyance where galvanized protection is beneficial

Material Consideration

Galvanized steel pipe nipples offer good corrosion resistance in atmospheric and non-aggressive environments but are not suitable for potable water systems unless certified. For systems with acidic or saline conditions, alternate materials such as stainless steel should be considered.
