2 inch x Close Black Steel Nipple

2" x Close Black Steel Nipple – Heavy-Duty Threaded Pipe Fitting

The 2" x Close Black Steel Nipple is engineered for high-strength, close-threaded connections in piping systems. Manufactured from seamless Schedule 40 black steel pipe, this fitting is designed for use in applications requiring secure coupling of male-threaded components with minimal spacing between them. Its short overall length and full-thread design make it ideal for confined installations and rigid alignment requirements.

This close nipple is commonly used in steam, oil, and gas systems, and is suitable for both commercial and industrial applications where pressure integrity and mechanical durability are critical. The fitting provides a continuous flow path while maintaining thread engagement across both ends, helping ensure system stability under operating stress.

Product Features

• ✅ Material: A106 Grade B Black Steel (ASTM-compliant seamless pipe)
• ✅ Nominal Size: 2 inches
• ✅ Length: Close (approx. 1.5" overall; threaded from end to end with no unthreaded body)
• ✅ Thread Type: NPT (National Pipe Taper), ANSI B1.20.1
• ✅ Pressure Rating: Suitable for use in pressure systems up to 150 psi (varies by system type and installation)

Installation Considerations

This nipple should be installed using compatible NPT-threaded fittings and appropriate thread sealant or PTFE tape to prevent leakage. Due to the short length, ensure pipe threads are not over-tightened, which can cause galling or thread damage. Ideal for rigid assemblies and systems requiring fixed alignment with minimal distance between pipe sections.

Common Applications

The 2" x Close Black Steel Nipple is frequently used in:

• • Natural gas and propane distribution systems
• • Steam and condensate piping
• • Compressed air systems
• • Process piping in manufacturing and mechanical facilities

Did You Know?

Close nipples are fully threaded to eliminate the unthreaded shoulder found in standard-length nipples, allowing fittings to join with minimal gap—critical for mechanical assemblies and space-constrained installations.

Engineered for reliability and performance, the 2" x Close Black Steel Nipple delivers rugged construction and tight-tolerance threading required for demanding industrial and commercial applications.
