1/4 inch x 6 inch Black Steel Nipple

1/4" x 6" Black Steel Pipe Nipple – Threaded Schedule 40 for Pressure Systems

This 1/4" x 6" black steel nipple is a straight pipe segment threaded at both ends, manufactured to Schedule 40 standards for integration into threaded pressure systems. Commonly used in gas, oil, and hydronic applications, this component is constructed from black steel to ensure mechanical durability and dimensional stability under operating loads.

Each nipple is machine-threaded to ANSI/ASME B1.20.1 standards, offering consistent thread engagement and compatibility with other NPT fittings. The black finish indicates that the fitting is intended for non-corrosive or indoor environments where galvanization is not required.

Performance Features

• ✅ Material: ASTM A53 Grade A black steel pipe body for strength and temperature resistance
• ✅ Thread Type: NPT male threads both ends for secure mechanical sealing
• ✅ Wall Thickness: Schedule 40, suitable for moderate pressure applications
• ✅ Length: 6 inches overall, nominal size 1/4 inch
• ✅ Use Case: Designed for use in compressed air, gas distribution, or hot water closed-loop systems

Installation Guidance

Use standard thread sealant (PTFE tape or pipe dope) during installation to ensure leak-free joints. Install with appropriate hand tools such as pipe wrenches to achieve torque without over-stressing threads. Avoid overtightening to preserve thread integrity and minimize deformation in fittings and mating components.

Note on Usage

Black steel pipe nipples are intended for applications that do not involve potable water. For systems requiring corrosion resistance or drinking water compatibility, consider galvanized or stainless alternatives. Always verify material compatibility with system media and local code requirements.
