1-1/4" x 3/4" Galvanized Iron Reducing Tee – FNPT Threaded Fitting for Pipe Branching

The 1-1/4" x 3/4" Galvanized Iron Reducing Tee is a malleable iron fitting designed for pipe branching in threaded piping systems. This tee features three female NPT connections and allows for a smooth reduction from a 1-1/4" run to a 3/4" branch, making it suitable for general utility, air, water, gas, or low-pressure steam lines.

Manufactured to conform with ANSI/ASME B16.3 standards and hot-dip galvanized per ASTM A153, this fitting provides resistance to corrosion and long-term durability. It is used in both commercial and residential systems where galvanized iron piping is specified and a size transition is required at a branch junction.

Performance Features

• Cast Malleable Iron Body: Provides excellent mechanical strength and impact resistance for structural reliability in high-demand environments.
• Hot-Dip Galvanized Coating: Enhances corrosion resistance, especially in environments with moisture or outdoor exposure.
• National Pipe Thread (NPT): Standard tapered threads for secure, pressure-rated connections with pipe sealant or Teflon tape.
• Pressure Rating: Suitable for up to 300 PSI non-shock for air, oil, or water; and 150 PSI for saturated steam service.

Specifications

• Material: ASTM A197 malleable iron
• Finish: Zinc-coated via hot-dip galvanization
• End Connections: FNPT x FNPT x FNPT
• Dimensions: 1-1/4” run, 3/4” branch
• Standards: ASME B16.3; coating per ASTM A153

Typical Applications

Used to connect and reduce branch pipe size in:

• Potable and non-potable water distribution systems
• Low-pressure steam or condensate lines
• Compressed air systems
• Natural gas or LP piping (where approved)

Installation Guidance

Use pipe thread compound or PTFE tape on male threads. Tighten with hand torque initially, then complete with a wrench while supporting the fitting to prevent deformation. Avoid overtightening to preserve thread integrity and fitting structure.

Note:

This fitting is intended for use in non-corrosive or moderately corrosive applications and is not recommended for underground installation unless protected against soil contact and corrosion.

The 1-1/4" x 3/4" Galvanized Iron Reducing Tee is a pressure-rated solution designed for consistent mechanical performance in multi-branch systems. Its corrosion resistance, dimensional accuracy, and code compliance make it a reliable component for any threaded piping assembly.
