1/2 inch x 1/2 inch x 3/4 inch Black Iron Reducing Tee Female x Female x Female

1/2 inch x 1/2 inch x 3/4 inch Black Malleable Iron Reducing Tee – F/F/F Threaded Tee for Gas, Water, and Steam Piping

The 1/2 inch x 1/2 inch x 3/4 inch Black Iron Reducing Tee is a threaded malleable iron fitting designed for use in low- to medium-pressure piping systems. It allows for a 90-degree branch connection while reducing to a smaller outlet size, making it suitable for various fluid distribution networks including water, steam, air, and gas systems.

This fitting features three female National Pipe Tapered (NPT) threads and is engineered in accordance with ANSI and ASME dimensional standards. Manufactured from ASTM A197 malleable iron and finished with a black coating, it provides durability in non-corrosive environments and is commonly installed in mechanical, industrial, and commercial plumbing systems.

Product Features

• ✅ Malleable Iron Construction – Conforms to ASTM A197 for strength, impact resistance, and long-term service in non-corrosive systems.
• ✅ Threaded Female x Female x Female (FPT) – Tapered NPT threads per ANSI B1.20.1 for compatibility with carbon steel, brass, or other black iron pipe fittings.
• ✅ Reducing Side Outlet – 3/4 inch branch outlet allows directional reduction without additional fittings or couplings.
• ✅ Black Finish – Intended for use in closed system applications where galvanizing is not required, such as steam or gas.
• ✅ Code Compliant – Designed for use in accordance with applicable plumbing, mechanical, and fuel gas codes.

Applications

Commonly used in residential and commercial piping systems requiring size transitions and 90° directional branching. Typical installations include hot and cold water lines, low-pressure steam systems, natural gas distribution, and compressed air service where corrosion resistance is not critical.

Installation Considerations

Threads should be properly sealed using PTFE tape or pipe joint compound approved for the system media. Avoid overtightening, which may cause cracking or distortion of the fitting. Ensure alignment to prevent cross-threading during assembly. This fitting is not intended for potable water or corrosive media unless properly lined or coated.

The 1/2 inch x 1/2 inch x 3/4 inch Black Iron Reducing Tee provides a reliable connection point for branching and reducing in threaded systems. Manufactured to industry standards, it supports efficient layout configurations and long-term performance in demanding applications.
