1-1/4 inch x 60 inch Black Steel Nipple

1-1/4" x 60" Black Steel Pipe Nipple – Threaded Connector for Gas, Steam, and Mechanical Systems

The 1-1/4" x 60" black steel nipple is a straight, Schedule 40 pipe segment with male NPT threads on both ends, designed for use in low-pressure fluid and gas distribution systems. Commonly utilized in industrial, commercial, and mechanical applications, it extends pipe runs or joins system components over a long distance without additional fittings.

Manufactured from welded or seamless carbon steel pipe per ASTM A53 or A106 standards, this nipple is suitable for use in aboveground gas lines, steam systems, and other non-potable applications where corrosion resistance and structural integrity are required.

Technical Specifications

• Nominal Size: 1-1/4 inch
• Length: 60 inches overall (including threaded ends)
• Material: Carbon steel, black finish (non-galvanized)
• Threading: NPT (ANSI B1.20.1) – Male x Male
• Wall Type: Schedule 40 (standard weight)
• Applicable Standards: ASTM A53 Grade A/B, ASME B1.20.1

Common Applications

• Natural gas and propane piping systems (aboveground)
• Low-pressure steam lines and condensate returns
• Mechanical piping in HVAC and industrial process systems
• Air or water distribution lines (non-potable)

Installation Guidelines

Pipe nipples must be installed using appropriate thread sealant or PTFE tape to prevent leaks. Proper support should be used for long runs to reduce stress at joint connections. This fitting is intended for use in threaded pipe systems and should not be welded or buried without additional protective treatment.

Performance Notes

Black steel pipe offers excellent strength and high working pressure tolerance, making it a reliable choice for systems where corrosion resistance is not a primary concern. Not approved for use in potable water systems under current lead-free regulations.

Summary

The 1-1/4" x 60" black steel nipple provides a durable and code-compliant solution for extending or connecting pipe runs in threaded mechanical systems. Its standardized construction supports consistent performance in gas, air, and steam applications across a wide range of operating conditions.
