1-1/2 inch x 60 inch Black Steel Nipple

1-1/2” x 60” Black Steel Nipple – Threaded Pipe Extension for Mechanical Systems

The 1-1/2” x 60” Black Steel Nipple is a threaded pipe segment manufactured for use in mechanical, plumbing, and gas piping systems. Designed with male NPT threads on both ends, this fitting enables direct connections between compatible threaded components, allowing for long-span pipe extensions without welding or grooving.

Constructed from carbon steel with a black finish, this nipple is suited for use in systems conveying non-potable water, low-pressure steam, air, and natural gas. It is intended for use in closed piping networks where corrosion protection from coatings or galvanization is not required due to installation conditions.

Product Attributes

• ✅ Carbon Steel Construction — Fabricated from ASTM-compliant black steel pipe for strength and dimensional reliability.
• ✅ NPT Threaded Ends — Tapered threads manufactured to ASME B1.20.1 specifications for leak-resistant connections with compatible components.
• ✅ Extended Length — 60-inch form factor supports long-span connections in layouts requiring minimal joint counts.
• ✅ Schedule 40 Wall Thickness — Standard for general-use mechanical and HVAC piping applications.

Technical Specifications

• Nominal Size: 1-1/2 inch
• Length: 60 inches (5 feet)
• Material: Carbon steel, black finish
• Thread Type: NPT (male) per ASME B1.20.1
• Wall Thickness: Schedule 40 (typical)

Application Scope

Commonly installed in fuel gas, hydronic heating, fire protection branch lines, air compressor systems, and other industrial or commercial piping where long-run, rigid connections are required. Not recommended for direct potable water use unless specified with a certified protective coating.

Installation Notes

Use with appropriate pipe sealants (PTFE tape or pipe dope) on threads to ensure a pressure-tight seal. Torque and thread engagement should be applied per manufacturer and code guidelines to prevent galling or over-tightening. Suitable for vertical and horizontal installations within structural supports.

The 1-1/2” x 60” Black Steel Nipple provides a high-integrity, code-compliant connection option for professionals working in systems where strength, alignment, and reliability are essential across extended runs.
