3/4 inch x 2 inch Black Steel Nipple

3/4" x 2" Black Steel Nipple – Short-Run Threaded Connector

The 3/4" x 2" Black Steel Nipple is designed for use in high-pressure piping systems where a short, rigid, male-threaded connection is required. Fabricated from Schedule 40 black steel pipe, this fitting is suitable for natural gas, air, steam, and non-potable water applications in both commercial and industrial environments.

Each nipple is precision-machined with NPT threads and finished with a black oxide coating, providing surface protection and dimensional consistency for critical joint integrity. The 2-inch length makes it ideal for compact piping layouts where tight clearances are present.

Product Characteristics

• ✅ Standard NPT Threads Conforms to ANSI/ASME B1.20.1 for tapered pipe threads to ensure a reliable, pressure-rated seal.
• ✅ Uniform Wall Thickness Provides structural integrity and consistent flow in pressurized piping networks.
• ✅ Short-Length Design Optimized for compact installations or spacing requirements between components.

Technical Specifications

• Nominal Size: 3/4 inch
• Length: 2 inches
• Material: Schedule 40 Black Steel
• Connection: Male NPT Threaded x Threaded
• Applications: Gas distribution lines, hydronic systems, compressed air networks, and industrial piping installations

Installation Guidelines

Threaded black steel nipples should be installed using approved thread sealant or PTFE tape to prevent leakage. Proper torque application and alignment are essential to avoid cross-threading or mechanical stress on mating components. Use of this fitting should follow applicable ASME and IPC mechanical code specifications for pressurized systems.

Typical Use Cases

Commonly implemented in gas manifolds, boiler system loops, air compressor setups, and branch pipe extensions. The 2-inch nipple serves as an effective connector where spacing is limited and support for fittings or valves is required within short distances.

Note on System Compatibility

Black steel fittings are not recommended for potable water service due to the risk of internal corrosion. Their use is appropriate for closed-loop and sealed-system applications requiring strength, temperature resistance, and reliability under pressure.

The 3/4" x 2" Black Steel Nipple offers dependable service life and precision threading for professional-grade installations in utility and mechanical piping systems.
