2 inch x 3/4 inch Black Iron Reducing Coupling Female x Female

2 Inch x 3/4 Inch Black Iron Reducing Coupling – Threaded Female Connections

This 2 inch x 3/4 inch black iron reducing coupling is designed for use in systems requiring a secure transition between two different pipe diameters. Constructed from robust black malleable iron, this coupling provides strong mechanical integrity and is commonly used in gas, air, and low-pressure steam applications where threaded connections are specified.

Specifications

• Material: Black malleable iron
• Connection Type: Threaded female x female (NPT)
• Size: 2 inch inlet x 3/4 inch outlet
• Conformance: Meets ASTM A197 and ASME B16.3 standards
• Pressure Rating: Suitable for non-potable low- to medium-pressure applications

Installation Guidelines

This fitting should be installed with pipe joint compound or PTFE tape to ensure a proper seal. Proper torque should be applied to avoid thread damage while ensuring leak resistance. Designed for use with steel pipe systems, this coupling is not suitable for potable water or corrosive fluid service unless properly coated or lined.

Key Features

• Heavy-duty Construction: Provides high tensile strength and resistance to vibration
• Corrosion Resistance: Black oxide finish offers limited protection in dry environments
• Thread Compatibility: NPT threads ensure a consistent and compatible fit with standard pipe dimensions

Applications

Commonly used in compressed air lines, natural gas distribution, fire protection systems (where code allows), and low-pressure steam systems. The reducing design is particularly useful in retrofit scenarios or when adapting larger diameter supply lines to smaller distribution piping.

Note

Black iron fittings are not rated for use with potable water unless they have a protective coating or lining. Always verify system compatibility with local code requirements and material specifications before installation.

This 2 inch x 3/4 inch black iron reducing coupling is an essential component in any professional-grade mechanical piping system requiring durability and consistent thread performance in non-potable service environments.
