1/2 inch x 2 inch Black Steel Nipple

1/2" x 2" Black Steel Pipe Nipple – Threaded Schedule 40 for Pressure Applications

The 1/2" x 2" Black Steel Nipple is a precision-machined pipe fitting designed for use in threaded steel piping systems. Commonly installed in gas, steam, oil, and hydronic heating applications, this Schedule 40 nipple delivers a rigid, high-strength connection for short pipe extensions or close-coupling between components.

Constructed from seamless black steel pipe per ASTM A53 standards, the nipple offers consistent wall thickness and concentric threading, which ensures reliable sealing in NPT-threaded systems. Its black oxide finish helps protect the steel during handling and short-term exposure to moisture.

Key Performance Features

• ✅ Seamless Carbon Steel Construction: Manufactured from Schedule 40 black steel pipe for strength and durability under working pressures.
• ✅ Threaded Ends: Machined with NPT male threads per ASME B1.20.1 for compatibility with a wide range of industrial and commercial piping systems.
• ✅ Compact Length: 2" length is ideal for connecting valves, fittings, or other components in tight spaces or limited-clearance areas.
• ✅ Corrosion-Resistant Coating: Black finish provides a protective barrier in non-potable or gas line environments.
• ✅ Pressure Rating: Suitable for moderate-pressure applications consistent with Schedule 40 pipe specifications.

Specifications

• Nominal Size: 1/2 inch
• Length: 2 inches (close pattern)
• Material: ASTM A53 Grade A/B Black Steel
• Wall Thickness: Schedule 40
• Ends: Male NPT x Male NPT
• Application: Steam, gas, air, non-potable water

Installation Considerations

To ensure leak-free performance, apply pipe joint compound or PTFE thread sealant to male threads prior to installation. Tighten to spec using a pipe wrench. Avoid overtightening, which can cause thread distortion. This nipple is intended for non-potable systems and should not be used where contact with drinking water occurs unless protected by appropriate lining or barriers.

Common Applications

The 1/2" x 2" black steel nipple is widely used in:

• Natural gas and propane distribution piping
• Steam heating and condensate return systems
• Hydronic system boiler piping
• Low-pressure compressed air lines

Did You Know?

Black steel pipe fittings, unlike galvanized alternatives, are preferred for gas line installations due to their strength and resistance to flaking or delamination under high heat.

Choose the 1/2" x 2" Black Steel Pipe Nipple when your job demands dependable performance in a compact format. Engineered to meet industrial tolerances, it’s a core component for any mechanical or gas piping layout where reliability is non-negotiable.
