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

1-1/4" x 3/4" x 3/4" Black Malleable Iron Reducing Tee – Threaded FPT

The 1-1/4" x 3/4" x 3/4" black malleable iron reducing tee is a Class 150 fitting engineered for use in low- to medium-pressure piping systems. This tee features three female National Pipe Thread (NPT) connections, allowing for secure branch line integration between different pipe sizes.

Manufactured in accordance with ASME B16.3 standards, this fitting is suitable for use in gas, oil, air, and hydronic systems. It is UL and FM listed where applicable and meets ASTM A197 for malleable iron castings. Its black finish (uncoated) makes it appropriate for non-potable systems and indoor applications where corrosion resistance is not a critical factor.
