1-1/2 inch x 12 inch Galvanized Steel Nipple

1-1/2" x 12" Galvanized Steel Pipe Nipple – Threaded Fitting for Pressure and Drainage Systems

The 1-1/2" x 12" Galvanized Steel Nipple is manufactured for use in high-demand fluid and gas conveyance systems. Fabricated from carbon steel and hot-dip galvanized for corrosion resistance, this fitting features NPT male threads on both ends, providing a secure connection between compatible threaded pipe and fittings.

Its extended 12-inch length is suitable for situations requiring longer reach without using additional couplings, reducing potential leak points and simplifying assembly. Ideal for use in both commercial and residential systems, including potable water, HVAC hydronic circuits, and compressed air lines.

Key Features

• ✅ Hot-Dip Galvanized Finish – Provides enhanced corrosion resistance for indoor and outdoor use.
• ✅ Schedule 40 Steel Pipe – Manufactured to ASTM A53/A733 for structural strength and dimensional integrity.
• ✅ Threaded Ends – Tapered NPT threads comply with ANSI B1.20.1 for pressure-tight joints.
• ✅ Extended Length – 12-inch overall length ideal for bridging longer pipe gaps with fewer joints.
• ✅ Pressure-Rated – Suitable for pressurized systems when installed per applicable codes with approved sealing materials.

Specifications

• Nominal Pipe Size: 1-1/2 inch
• Length: 12 inches (overall)
• Material: Carbon Steel (ASTM A53), Hot-Dip Galvanized
• Thread Type: NPT Male x NPT Male
• Wall Thickness: Schedule 40
• Standards: Meets ASTM A733, ANSI B1.20.1

Installation Guidelines

Use of thread sealant or PTFE tape is required to ensure leak-proof joints. Always verify system compatibility before installation, particularly in applications involving drinking water, steam, or gas. Threads should be clean and free of debris prior to tightening. Over-tightening can distort threads or crack fittings—follow torque recommendations based on material specs.

Common Applications

• Potable and non-potable water lines
• Low-pressure steam and air distribution
• Hydronic heating loops
• Industrial compressed gas systems (when approved)
• Pump, tank, and manifold connections

Additional Considerations

Galvanized steel is not recommended for use with acids or in environments where electrochemical reactions may degrade the coating. For potable systems, ensure local code compliance regarding the use of galvanized materials in domestic water applications.

The 1-1/2" x 12" Galvanized Nipple offers durable, corrosion-resistant performance where threaded pipe connections are required. Built to industry standards, this fitting supports system longevity and installation efficiency across a range of plumbing and mechanical installations.
