Sourced from qualified manufacturers adhering to industry specifications, this fitting supports code-compliant system assembly, minimizing installation delays and mitigating the risk of premature failure or rework. Ideal for new construction and retrofit tasks requiring threaded steel connections.

Performance-Focused Features

Built to meet the demands of professional mechanical contractors, this steel nipple offers:

• ✅ Precision Threading Machined NPT threads deliver accurate engagement and reduced galling risk.
• ✅ Corrosion-Resistant Coating Black oxide finish provides protection in non-potable systems and sealed applications.
• ✅ Thread Integrity Clean-cut threading ensures secure mating with standard fittings, reducing potential leak paths.
• ✅ High Tensile Strength Manufactured from carbon steel for use in gas, air, and hydronic systems under pressure.
• ✅ Dimensional Consistency Controlled production tolerances enable consistent system layout and repeatable installations.

Installation and Use

Threaded connections should be completed using approved sealing compounds or PTFE tape. Proper torque and alignment are critical to achieving a sealed, vibration-resistant joint. Commonly used in gas lines, closed-loop hydronic heating, and compressed air systems. Not rated for potable water.

Applications

Commonly implemented in mechanical rooms, equipment connections, and branch terminations in HVAC, fire protection, and fuel gas systems. Suitable for interior runs where black iron is acceptable under local code.

Industry Insight

Black steel pipe and nipples are widely preferred for their structural integrity and resistance to mechanical wear in gas transmission lines and industrial piping networks.

For system longevity and reduced maintenance demands, professionals rely on components that deliver strength, reliability, and code conformity. This Black Steel Nipple is engineered to support those objectives across varied jobsite conditions and system configurations.
