3/4 inch x 24 inch Black Steel Nipple

3/4” x 24” Black Steel Pipe Nipple – Designed for High-Strength Piping Systems

The 3/4” x 24” Black Steel Nipple is engineered for strength and longevity in pressure piping applications, providing a reliable means of extending pipe runs or joining components. Manufactured from welded schedule 40 black steel pipe, this nipple features NPT (National Pipe Thread) tapered male threads on both ends, offering a secure and tight seal for gas, air, or low-pressure steam systems.

Black steel pipe nipples like this one are commonly used in oil and gas, HVAC, and hydronic heating applications due to their ability to handle moderate to high temperatures and internal pressures. The 24-inch length makes it ideal for longer runs that require rigid support and minimal fittings, helping reduce potential leak points in the system.

Product Benefits

• ✅ Standardized Threading – NPT threads ensure compatibility with industry-standard fittings, valves, and couplings.
• ✅ Welded Carbon Steel Construction – Manufactured from ASTM A53 Grade A or equivalent black steel pipe for strength and dimensional accuracy.
• ✅ Corrosion-Tolerant Surface – Protective black oxide coating offers resistance to rust in dry and indoor environments.
• ✅ Machined Ends – Threads are precision-machined for smooth assembly and consistent sealing performance.

Technical Specifications

• Nominal Size: 3/4 inch
• Length: 24 inches (overall including thread length)
• Material: Carbon Steel (black finish)
• Schedule: 40 wall thickness
• Thread Type: NPT Male x Male
• Conforms To: ASTM A53, ASME B1.20.1 (threads)

Common Applications

This nipple is suitable for joining steel piping in a variety of applications:

• • Natural gas and propane systems
• • Low-pressure steam distribution
• • Compressed air systems
• • Water and oil transport lines (non-potable)

Installation Notes

For optimal performance, apply a thread sealant or PTFE tape to male threads during installation. Torque should be applied with a pipe wrench to ensure a tight seal, but overtightening should be avoided to prevent thread damage. Ensure that fittings and mating components also conform to NPT standards to maintain pressure integrity.

Did You Know?

Black steel pipe is favored in gas distribution due to its robustness and the absence of a galvanized coating, which can flake off in high-velocity systems and clog downstream components. Its uncoated finish is ideal for systems that do not require corrosion protection from moisture exposure.

The 3/4” x 24” Black Steel Nipple offers the durability and precision demanded by commercial and industrial piping applications. Whether you’re assembling a new gas line or extending an existing header, this fitting delivers strength and reliability with every installation.
