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

1/2 inch x 1/2 inch x 3/8 inch Black Malleable Iron Reducing Tee – Threaded Fitting for Gas and Fluid Distribution

The 1/2 inch x 1/2 inch x 3/8 inch Black Malleable Iron Reducing Tee is a Class 150 threaded fitting used to branch piping systems with dissimilar outlet sizes. Designed for general-purpose applications, this reducing tee features three female National Pipe Taper (NPT) threaded ends: two 1/2 inch openings and one 3/8 inch outlet. It enables a secure and corrosion-resistant connection in non-potable water, air, gas, or oil piping systems.

Manufactured in accordance with ASTM A197 and ANSI/ASME B16.3 specifications, the fitting is commonly used in mechanical, HVAC, and fuel gas installations. The black finish is suitable for indoor applications where galvanized protection is not required.

Product Specifications

• Size: 1/2 inch x 1/2 inch x 3/8 inch (FPT x FPT x FPT)
• Material: Malleable iron, ASTM A197
• Thread Standard: ANSI/ASME B1.20.1 (NPT threads)
• Pressure Rating: Class 150 – suitable for up to 300 PSI non-shock service at ambient temperatures
• Configuration: Reducing tee for branching to smaller-diameter pipe

Installation Guidelines

Use appropriate thread sealant or PTFE tape on male pipe threads before assembly. Align fittings carefully to avoid cross-threading. Tighten using standard pipe wrenches and avoid excessive torque to prevent cracking or distortion. All piping connections should be tested per system and local code requirements, especially in gas or pressure systems.

Typical Applications

This reducing tee is used to distribute flow from a main line to a smaller branch. It is commonly installed in:

• Fuel gas piping systems
• Hydronic heating loops
• Compressed air systems
• Low-pressure water distribution

It is appropriate for industrial, mechanical, and commercial system designs requiring a robust, pressure-rated connection.

Material Characteristics

Malleable iron offers a high strength-to-weight ratio and excellent impact resistance. The black finish provides basic corrosion resistance for use in dry environments. For outdoor or corrosive applications, galvanized or coated alternatives may be more appropriate.

The 1/2 inch x 1/2 inch x 3/8 inch Black Malleable Iron Reducing Tee is a dependable component in threaded mechanical assemblies, providing a durable and standardized solution for pipe size transitions within code-compliant piping networks.
