2″ x 5″ Black Steel Pipe Nipple – Threaded for Pressure-Grade Connections
The 2″ x 5″ black steel nipple is a seamless Schedule 40 fitting designed for high-integrity threaded connections in low- to medium-pressure applications. Fabricated from welded or seamless carbon steel pipe conforming to ASTM A53/A106 or equivalent standards, this component offers robust performance in mechanical and plumbing systems that require durability under stress.
Product Features
- Threaded NPT Ends – Machined to ANSI B1.20.1 standards, ensuring consistent fit with other threaded pipe and fittings.
- Schedule 40 Wall Thickness – Suitable for most general-purpose steam, gas, or water service lines.
- Black Coated Finish – Uncoated steel exterior with minimal oil film, ideal for oil and gas transport or fire suppression systems where galvanized coating is not permitted.
- Fabricated from Carbon Steel – Offers high tensile strength and excellent mechanical performance in demanding applications.
- Standard Length – Cut to a nominal 5-inch length for tight configurations or close coupling between system components.

Installation Notes
Installation should be performed using standard threading equipment and pipe wrenches. Use of thread sealant or PTFE tape is recommended to ensure a tight seal. Avoid overtightening to prevent thread distortion or cracking of connected fittings.
Application Range
Commonly used in oil and gas lines, hydronic heating loops, compressed air systems, fire sprinkler systems (where black steel is specified), and closed-loop water systems. It is not recommended for potable water unless appropriately coated or lined per local code requirements.
Code Compliance Advisory
Black steel nipples must be used in accordance with local mechanical and plumbing codes. For gas service, verify compatibility with national fuel gas code requirements and jurisdictional inspection standards.
This 2″ x 5″ black steel nipple provides a dependable, pressure-rated threaded solution for contractors requiring strength and longevity in steel piping systems. Ideal for retrofit or new mechanical installations where carbon steel is specified.
