2 inch x 6 inch Black Steel Nipple

2" x 6" Black Steel Pipe Nipple – Threaded for Pressure and Mechanical Systems

This 2" x 6" black steel nipple is manufactured for use in systems that require short-length, rigid, threaded connections. Commonly applied in commercial, industrial, and residential piping, it provides a secure link between components in water, steam, oil, or natural gas installations that fall under non-corrosive service conditions.

Fabricated from welded or seamless Schedule 40 black steel pipe, this nipple features male National Pipe Thread (NPT) ends cut to ANSI/ASME B1.20.1 standards. Its 6-inch length makes it suitable for system offsets, equipment connections, or terminating runs where short, precise spacers are required.

Professional-Grade Features

• ✅ Carbon Steel Construction Offers mechanical strength and durability under high-temperature and pressure-rated service.
• ✅ Black Oxide Finish Uncoated to support compatibility with gas, oil, and hydronic piping where galvanization is not permitted.
• ✅ Threaded NPT Ends Tapered male threads ensure tight joints with couplings, valves, and fittings when used with approved sealants.
• ✅ Precision-Cut Length Maintains dimensional accuracy for consistent makeup in pipe layout configurations.
• ✅ Industry-Standard Compliance Suitable for use in systems designed to applicable mechanical, plumbing, or gas code specifications.

Application Suitability

This nipple is commonly used in gas distribution lines, hydronic heating loops, oil piping, and closed-loop water systems. It is also utilized in steam systems and mechanical room installations where short, rigid threaded connectors are required between fixtures or system transitions.

Material and Installation Insight

Black steel is selected for environments where exposure to moisture is limited and coating is unnecessary or undesired. It is not recommended for potable water service. Use thread compound or PTFE tape for sealing. Wrench engagement should be limited to the threaded portion to avoid damaging the pipe body.

The 2" x 6" black steel nipple provides consistent performance and mechanical reliability where precision-length connectors are needed in code-compliant pressure systems.
