1-1/2 inch x 24 inch Galvanized Steel Nipple

1-1/2" x 24" Galvanized Steel Nipple – Schedule 40, Threaded Both Ends

The 1-1/2" x 24" galvanized steel nipple is a straight pipe section with NPT threads on both ends, designed for extending pipe runs or connecting components in threaded systems. Manufactured from Schedule 40 welded steel pipe and hot-dip galvanized per ASTM A153 standards, this fitting provides corrosion protection in both indoor and outdoor applications.

Galvanized steel nipples are suitable for mechanical, water distribution, and air systems, especially in environments where moisture or oxidation is a concern. The zinc coating serves as a sacrificial barrier, extending the service life of the underlying steel substrate.

Product Features

• ✅ Threaded Connections: NPT threads on both ends, machined to ANSI B1.20.1 for tight, pressure-rated joints.
• ✅ Hot-Dip Galvanized: Zinc-coated exterior resists rust and complies with common code requirements for non-potable water applications.
• ✅ Schedule 40 Wall Thickness: Provides strength and pressure capacity suitable for industrial, agricultural, and commercial piping systems.
• ✅ Welded Steel Pipe Body: Manufactured in accordance with ASTM A53 Type E or S for consistent structural performance.

Installation Considerations

Use thread sealant or PTFE tape on male threads prior to assembly to ensure a leak-resistant connection. Apply torque using pipe wrenches on the unthreaded portion of the nipple to avoid damaging threads. Confirm compatibility with adjoining materials and avoid contact with dissimilar metals unless isolated to prevent galvanic corrosion.

Application Scope

Commonly used in low-pressure water lines, HVAC systems, structural pipe supports, and compressed air networks. Suitable for irrigation, non-potable fluid handling, and mechanical piping installations requiring extended runs between threaded fittings.

Material Note

Galvanized steel is not recommended for use with potable water in certain jurisdictions due to the potential for zinc leaching. Always verify local code compliance and intended fluid compatibility before use.
