1/8 inch x Close Galvanized Steel Nipple

1/8" x Close Galvanized Steel Nipple – Threaded Connector for Compact Piping Transitions

The 1/8 inch x Close Galvanized Steel Nipple is designed for connecting two threaded components in minimal space applications. Fabricated from carbon steel and hot-dip galvanized for corrosion resistance, this close nipple provides a rigid, direct connection between fittings or pipe segments in pressurized or structural piping systems.

Its short length and male NPT threads on both ends make it ideal for configurations where piping layout requires the smallest possible spacing between components without the use of additional couplings. Common applications include branch terminations, threaded valve installations, or compact system tie-ins.

Performance and Construction Highlights

• ✅ Carbon Steel Base Material: Ensures strength and pressure resistance suitable for utility piping systems.
• ✅ Hot-Dip Galvanized Coating: Provides a barrier against rust and external environmental exposure.
• ✅ Close Nipple Length: Threaded nearly end-to-end with minimal unthreaded body for tight-clearance assemblies.
• ✅ Precision NPT Threading: Manufactured to ANSI/ASME B1.20.1 specifications for reliable sealing with compatible components.

Technical Specifications

• Nominal Size: 1/8 inch
• Length: Close (approx. thread-to-thread contact with minimal exposed barrel)
• Material: Hot-dip galvanized carbon steel
• Thread Type: Male NPT x Male NPT

Use Case Applications

This fitting is commonly used in small-diameter rigid piping systems for compressed air, non-potable water, and general mechanical services. It is especially suited for installations requiring minimal spacing between fittings such as instrument manifolds, gas lines, or valve stubs in confined enclosures.

Installation Considerations

Use pipe thread sealant or PTFE tape rated for the intended system media to ensure leak resistance. Torque application should be controlled to prevent distortion of mating threads. Due to the “close” design, it may be necessary to adjust mating part orientation prior to full engagement.

Material and Compliance Note

Galvanized steel nipples are not recommended for use in potable water systems where lead content or zinc leaching may pose a compliance concern. Always verify material compatibility and code requirements based on the application.

The 1/8" x Close Galvanized Steel Nipple offers a compact, corrosion-resistant solution for tight-tolerance connections in industrial, commercial, and utility-grade piping systems. Its durable construction supports reliable, long-term performance in both horizontal and vertical installations.
