1/2" Black Iron Tee – Threaded Branch Connector for Gas and Fluid Systems

The 1/2" Black Iron Tee is a malleable iron pipe fitting used to create a perpendicular branch connection in threaded piping systems. Designed for durability in gas, oil, steam, and air applications, this fitting features three female National Pipe Thread (NPT) connections for integration with standard 1/2" pipe.

Manufactured to industry specifications, this tee provides a rigid, pressure-rated solution for systems requiring structural integrity and resistance to mechanical stress. The black oxide finish offers surface protection during storage and handling and is suitable for indoor environments or systems that do not require corrosion-resistant coatings.

Technical Specifications

  • Material: Malleable Black Iron
  • Nominal Size: 1/2 inch
  • Connection Type: Female NPT x Female NPT x Female NPT
  • Finish: Black (oil-coated)
  • Application: Non-potable water, gas, air, oil, and steam piping systems
  • Standards: Conforms to ASTM A197 and ASME B16.3
  • Pressure Rating: 150 psi steam; 300 psi air, oil, or water (non-shock)

Key Features

  • Cast Malleable Iron Body – Withstands mechanical loads and thermal cycling in demanding system layouts.
  • NPT Threaded Ends – Precision-machined to ensure proper thread engagement and tight, leak-resistant seals.
  • Black Coated Surface – Minimizes oxidation during transport and installation; not suitable for potable water or corrosive environments.
  • Standardized Fit – Compatible with other Schedule 40 black steel pipe and fittings for seamless integration.

Typical Applications

Used in low- to medium-pressure piping systems for gas distribution, compressed air systems, and closed-loop hydronic networks. Often installed in mechanical rooms, utility risers, and industrial process piping where branch lines are required at 90° angles.

Installation Guidance

Install using appropriate thread sealant or PTFE tape to ensure a pressure-tight joint. Threads should be clean and free of debris. Use a calibrated torque wrench or equivalent method to avoid over-tightening, which may compromise thread integrity or alignment.

Material Performance Note

Black iron fittings are not intended for use in potable water systems due to the potential for corrosion and lack of a protective galvanic barrier. They are, however, highly durable under dry and non-corrosive service conditions where structural strength and thread consistency are essential.

The 1/2" Black Iron Tee offers a reliable solution for distributing flow in branched piping systems. When installed per code and manufacturer specifications, it delivers long-term performance in mechanical and fuel gas applications.
