1-1/4 inch x 72 inch Steel Nipple

1-1/4" x 72" Black Steel Nipple – Built for Strength and Performance

The 1-1/4" x 72" black steel nipple is engineered to provide robust, extended-length connections in high-demand piping systems. Manufactured from seamless Schedule 40 black steel, this fitting is ideal for transporting natural gas, oil, air, and water in both commercial and industrial settings.

Key Features and Advantages

• Seamless Carbon Steel Construction: Produced from high-strength black steel for superior mechanical durability and high-pressure resistance.
• Threaded Ends: NPT (National Pipe Tapered) threads on both ends ensure secure, tight connections compatible with standard threaded pipe fittings.
• Corrosion-Resistant Coating: Factory-applied black oxide finish enhances surface durability and minimizes rust in dry environments.
• Extended Length Application: At 72 inches, this nipple is suitable for longer pipe runs, making it a practical choice in systems requiring fewer joints and reduced installation time.

Technical Specifications

• Material: Black Carbon Steel (ASTM A106 Grade B or equivalent)
• Nominal Size: 1-1/4 inch
• Length: 72 inches
• Thread Type: NPT (Male x Male)
• Wall Thickness: Schedule 40
• Application: Gas, air, oil, or water piping systems

Installation Guidelines

Before installation, verify thread condition and cleanliness. Apply thread sealant or PTFE tape to ensure leak resistance. Use a pipe wrench with appropriate jaw protection to avoid thread damage. Adhere to local mechanical and gas codes, particularly in pressure-rated systems.

Common Use Cases

This long-length nipple is widely used in natural gas lines, compressed air systems, hydronic heating loops, and commercial process piping. It provides a solution for installations where structural stability and extended reach are needed without coupling multiple shorter sections.

Did You Know?

Using longer black steel nipples like this one reduces the number of joints in a system, lowering the potential for leaks and improving overall flow performance.

The 1-1/4" x 72" black steel nipple offers the mechanical integrity and compatibility professional contractors rely on for code-compliant installations. Built for demanding environments, it delivers extended reach and dependable sealing in pressure-driven systems.
