1/2 inch x 60 inch Black Steel Nipple

1/2" x 60" Black Steel Nipple – Schedule 40, NPT Threaded Pipe Extension

The 1/2" x 60" Black Steel Nipple is a precision-machined Schedule 40 fitting designed for use in threaded mechanical piping systems. Manufactured from welded or seamless carbon steel pipe in accordance with ASTM A53 or A106 specifications, this nipple features male National Pipe Taper (NPT) threads on both ends, providing a secure and reliable means of connecting piping components over extended lengths.

Suitable for use in low-pressure gas, air, steam, and hydronic applications, this nipple is commonly employed where long pipe extensions are needed without the requirement for intermediate fittings. The black oxide coating provides moderate corrosion resistance in dry environments or concealed locations, and is appropriate for use in both commercial and industrial settings.

Technical Specifications

• Nominal Pipe Size: 1/2 inch
• Length: 60 inches (5 feet)
• Wall Thickness: Schedule 40 (standard weight)
• Material: Welded or seamless black carbon steel (ASTM A53 Grade B / A106 Grade B)
• Connection Type: Male NPT x Male NPT (ASME B1.20.1)
• Finish: Black oxide coating
• Pressure Rating: Up to 150 PSI for air/gas service (varies by system design and application)

Key Performance Attributes

• ✅ Thread Accuracy: Machined to ANSI B1.20.1 tolerances for consistent joint fit and sealing.
• ✅ Structural Strength: Schedule 40 thickness provides mechanical durability under dynamic system loads.
• ✅ Extended Length Capability: Ideal for installations requiring minimal coupling joints or directional changes.
• ✅ Corrosion-Resistant Finish: Black coating protects bare steel during handling, transport, and dry-service use.

Common Applications

This 60" black nipple is used in various utility and process systems, including:

• Natural gas and propane distribution
• Low-pressure steam and condensate return
• Closed-loop hydronic heating and cooling lines
• Compressed air systems

Installation Guidelines

Use thread sealant or PTFE tape on male threads before assembly. Tighten with standard pipe wrenches to recommended torque levels. Pipe must be supported per applicable plumbing and mechanical codes to prevent stress at joint connections and ensure long-term system integrity.

Code & Compliance Notes

Not intended for potable water systems unless explicitly rated and certified for lead-free compliance. Verify compatibility with local gas and plumbing codes prior to installation.

Conclusion

The 1/2" x 60" Black Steel Nipple is a durable, code-compliant solution for extended-length threaded connections in gas, air, and mechanical systems. With its accurate machining, Schedule 40 wall integrity, and black finish, it provides the strength and reliability needed for demanding construction and service environments.
