2-1/2 inch Black Iron Tee – Threaded Branch Connector for Pressure Pipe Systems

The 2-1/2 inch Black Iron Tee is a robust malleable iron fitting engineered to form 90-degree branch connections within threaded pipe assemblies. Designed for use in gas, air, steam, and closed-loop hydronic systems, this fitting provides durable performance in high-pressure and high-temperature applications.

Manufactured in accordance with applicable ASME and ASTM specifications, the tee is constructed from black malleable iron with threaded female ends to accommodate standard NPT pipe threads. Its precision-cut threads and solid wall design ensure mechanical stability and consistent sealing during system pressurization.

Application-Driven Performance

• ✅ Female NPT Threads Cut to ANSI/ASME B1.20.1 specifications for tight mechanical engagement and system compatibility.
• ✅ Load-Bearing Design Supports full system pressure ratings, suitable for horizontal and vertical pipe runs in utility systems.
• ✅ Corrosion-Resistant Finish Black oxide coating provides basic protection in dry or enclosed environments.
• ✅ Dimensional Consistency Machined to ensure proper alignment and flow balance across branch and run outlets.

Technical Specifications

• Fitting Type: Tee (Straight Run with 90° Branch)
• Nominal Size: 2-1/2 inch
• Material: Black Malleable Iron
• Connection Type: FIP x FIP x FIP (National Pipe Thread)
• Standards: Typically conforms to ASTM A197, ASME B16.3, and ANSI B1.20.1

Installation Guidelines

Apply thread sealant or PTFE tape on all male threads before installation. Hand-tighten first, followed by wrench tightening to recommended torque based on pipe size and system pressure rating. Inspect threads for damage or debris prior to assembly. Follow local codes, particularly when installing in fuel gas or steam systems.

Common Use Cases

Typical installations include gas distribution systems, boiler piping, air compressor lines, and mechanical room manifolds. The 2-1/2 inch tee is often used in larger-diameter industrial branch connections and retrofits where structural integrity and precise alignment are critical.

Usage Advisory

Black iron fittings are not intended for potable water use. Their mechanical strength and thermal resistance make them ideal for industrial applications, especially in sealed or pressure-rated environments where corrosion protection is not externally applied.

The 2-1/2 inch Black Iron Tee is built to meet the demands of high-performance installations, supporting reliable and secure connections in code-compliant mechanical and industrial piping systems.
