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

3/4 inch x 3/4 inch x 1/2 inch Black Malleable Iron Reducing Tee – FNPT Branch Fitting

The 3/4 inch x 3/4 inch x 1/2 inch Black Malleable Iron Reducing Tee is designed for use in threaded piping systems requiring a 90-degree branch connection. Constructed from ASTM A197-grade black malleable iron, this tee features two 3/4 inch female NPT inlets and one 1/2 inch female NPT outlet, offering a compact solution for reducing branch lines within fluid and gas conveyance systems.

Commonly installed in water, steam, air, and natural gas piping networks, this fitting is compatible with standard Schedule 40 and Schedule 80 steel pipe. The black finish is suited for above-ground, non-corrosive environments, making it ideal for use in heating, fire protection, and mechanical system layouts where durability and mechanical strength are required.

Installation Guidelines

Threaded joints should be assembled using an approved thread sealant or PTFE tape. Avoid over-tightening to prevent cracking or deformation. Pipe wrenches should be applied on adjacent fittings to distribute force evenly. Always follow local code requirements for pressure systems, especially in gas and mechanical applications.

Common Applications

This reducing tee is frequently used in fuel gas systems, hydronic heat distribution, compressed air networks, and branch take-offs in mechanical systems. Its compact form factor and mechanical reliability make it suitable for both new installations and system retrofits in commercial, industrial, and residential settings.

Material Use Note

Black malleable iron fittings are intended for non-potable systems and should not be used in drinking water applications unless internally coated or approved by the authority having jurisdiction. Not recommended for use in corrosive environments unless properly protected.

The 3/4 inch x 3/4 inch x 1/2 inch Black Malleable Iron Tee delivers reliable mechanical strength and long service life for reducing branch connections in pressurized piping systems. Engineered for compatibility with standardized piping components, it supports safe, code-compliant installations across a wide range of service applications.
