2 inch Black Malleable Iron Tee – Threaded F-F-F for Gas and Water Distribution

The 2 inch Black Malleable Iron Tee is a triple-female threaded fitting used to join three sections of pipe at a 90-degree angle. Manufactured from ASTM A197 malleable iron and finished with a protective black coating, this fitting is engineered for use in low-pressure gas, steam, and water distribution systems in commercial and residential applications.

Key Product Advantages

• ✅ Threaded NPT Ends: Complies with ANSI B1.20.1 standards for National Pipe Taper (NPT) threads, providing a secure, leak-resistant seal when properly installed with thread sealant.
• ✅ Malleable Iron Body: Offers excellent ductility and impact resistance for robust mechanical performance under installation torque and system stress.
• ✅ Black Finish: Suitable for non-potable applications including fuel gas, fire protection, and HVAC systems; not intended for potable water due to lack of corrosion-resistant lining.
• ✅ Pressure-Rated: Typically rated up to 150 psi for steam and 300 psi for non-shock water, air, or oil applications, depending on assembly integrity and code adherence.
• ✅ Versatile Integration: Allows for lateral take-offs or directional flow control within piping assemblies in utility rooms, mechanical closets, or service risers.

Technical Specifications

• Material: ASTM A197 Grade malleable cast iron
• Finish: Black (oil-coated)
• Nominal Size: 2 inch
• Connection Type: Threaded (FPT x FPT x FPT)
• Compliance: Meets ASME B16.3 and UL/FM standards when specified

Typical Applications

This 2 inch black iron tee is widely used in low-pressure systems where directional flow between pipe branches is required. Typical installations include:

• Natural gas or propane piping
• Steam and hot water heating loops
• Compressed air systems
• Fire sprinkler mains (non-potable)

Installation Notes

Use pipe joint compound or PTFE tape on male threads to achieve a proper seal. Avoid over-torquing to prevent thread distortion. Ensure alignment and support across all three directions to minimize stress on the fitting during service.

Did You Know?

Malleable iron is preferred over cast iron in many pressure-rated plumbing systems because of its superior ability to flex without fracturing, which enhances reliability during temperature swings and mechanical vibrations.

For professionals seeking a robust, code-compliant tee fitting for gas and water systems, the 2 inch Black Malleable Iron Tee offers dependable performance and compatibility across a wide range of field applications.
