1 inch x 3 inch Black Steel Nipple

1" x 3" Black Steel Nipple – Threaded Connector for Pressure Systems

The 1" x 3" Black Steel Nipple is a precision-cut, threaded fitting used for joining sections of pipe in pressurized systems. Manufactured from schedule 40 black steel, this nipple is engineered to handle air, water, oil, steam, and gas in a wide range of industrial and commercial applications.

Its uniform threading and dimensional accuracy meet ANSI/ASME B1.20.1 pipe thread standards, ensuring compatibility with other NPT-threaded components. Black steel construction offers strength and heat resistance, making this nipple suitable for systems requiring robust performance and minimal maintenance.

Product Features

• ✅ Schedule 40 Wall Thickness – Supports moderate to high pressure installations across mechanical systems.
• ✅ NPT Threads – National Pipe Tapered threads on both ends for secure, leak-resistant sealing.
• ✅ Welded Carbon Steel Construction – Provides structural integrity and thermal resilience for heating and gas applications.
• ✅ Corrosion-Resistant Coating – Black finish inhibits surface oxidation during storage and operation.
• ✅ Standard Pipe Compatibility – Designed for integration with 1" nominal steel piping and fittings.

Technical Specifications

• Material: Welded Black Carbon Steel
• Nominal Size: 1 inch
• Length: 3 inches
• Thread Type: NPT (Male x Male)
• Standard Compliance: ASTM A53 / ASME B1.20.1

Application Areas

Frequently used in gas distribution systems, compressed air lines, hydronic heating loops, and fire sprinkler assemblies. The 3" length provides spacing between valves, tees, and elbows where short extensions are necessary.

Installation Guidance

Apply pipe thread sealant or PTFE tape to both threaded ends prior to tightening. Use appropriate torque with a pipe wrench to prevent thread deformation. Suitable for horizontal and vertical installations in both temporary and permanent systems.

For contractors seeking durability and thread integrity in pressure-rated piping, the 1" x 3" Black Steel Nipple delivers industry-standard performance backed by reliable material strength and dimensional consistency.
