1/2 inch x 5 inch Black Steel Nipple

1/2” x 5” Black Steel Nipple – Threaded Connector for Pressure Piping Systems

The 1/2” x 5” Black Steel Nipple is a Schedule 40 welded steel fitting designed for use in threaded piping systems where a straight extension is required. Manufactured to meet ANSI and ASTM dimensional standards, it offers a precise connection in gas, air, and water distribution systems across commercial, industrial, and mechanical applications.

This nipple is fabricated from black-coated carbon steel pipe and features NPT (National Pipe Thread) male threads on both ends, machined to ANSI B1.20.1 specifications. It is suitable for use in systems operating under moderate pressure and temperature, where corrosion resistance is provided by the black oxide surface finish in non-potable environments.

Product Features

• ✅ Nominal Size: 1/2 inch
• ✅ Length: 5 inches
• ✅ Material: Schedule 40 black carbon steel pipe
• ✅ Connection Type: Male NPT x Male NPT, both ends threaded
• ✅ Thread Standard: ANSI/ASME B1.20.1

Performance Characteristics

• ✅ Pressure-Resilient Suitable for use in low- to mid-pressure systems such as natural gas, compressed air, and closed-loop hydronic loops
• ✅ Threaded Integrity Precision threading ensures uniform engagement and reduces potential for leaks with proper sealing techniques
• ✅ Internal Diameter Consistency Maintains flow performance across system segments
• ✅ Structural Strength Ideal for systems subject to vibration or moderate thermal cycling

Installation Notes

Threaded nipple installation requires application of PTFE tape or thread compound to ensure leak-free connections. Avoid over-torquing to preserve thread shape and sealing surface. Nipple should be pressure-tested in accordance with jobsite requirements before system commissioning. Adhere to applicable codes (e.g., IPC, NFPA, ASME B31) when used in fuel gas or pressurized systems.

Use Cases

The 1/2” x 5” Black Steel Nipple is frequently used in gas risers, boiler connections, industrial air systems, and manifold extensions. Its length makes it appropriate for bridging gaps or offsetting components where alignment and strength are required in a confined footprint.

Material Advisory

Black steel components are not intended for potable water use due to internal corrosion risk. Their primary use is in sealed or controlled mechanical systems where durability and pressure handling are priorities.

This 1/2” x 5” Black Steel Nipple is engineered for consistent field performance in threaded pipe assemblies where dimensional accuracy and mechanical resilience are required.
