Description
300# Extra Heavy Galvanized Malleable Iron Reducing Tee
300# extra heavy galvanized malleable iron reducing tees create a 90-degree reduced branch connection in a threaded piping system. The two equal-size female NPT run openings and smaller female NPT branch opening provide a durable transition for demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications where corrosion resistance and a galvanized finish are required.

How a Threaded Reducing Tee Works
A threaded reducing tee has three female NPT openings arranged with two equal-size inline run connections and one smaller branch connection positioned at 90 degrees. Compatible male-threaded pipe, pipe nipples, valves, or fittings thread into each opening, allowing the main line to continue through the run while transitioning to a smaller branch line.

Frequently Asked Questions
What is a 300# galvanized malleable iron reducing tee used for?
It creates a 90-degree branch connection from the main threaded piping run while reducing to a smaller branch size.
How are the reducing tee sizes listed?
Sizes are listed as run x run x branch. The first two dimensions identify the equal-size inline run openings, and the third dimension identifies the smaller branch opening.
Does this reducing tee have female threads on all three openings?
Yes. ASC Figure 3164R has female NPT threaded connections on both run openings and the branch opening.
What is the benefit of the galvanized finish?
The galvanized finish provides added corrosion resistance compared with an unfinished black malleable iron fitting.
What pressure class is this fitting?
This fitting is manufactured as a 300# / Class 300 extra heavy threaded malleable iron fitting.
What size configurations are available?
Available product variations range from 3/4" x 3/4" x 1/2" through 3" x 3" x 2".
What standards and listings apply?
The fitting conforms to ASME B16.3, ASTM A197, and ASME B1.20.1 requirements. ASC lists its Class 300 malleable iron fittings as UL Listed.
Should thread sealant be used during installation?
Use an approved pipe-thread sealant or thread tape selected for the piping media, pressure, temperature, applicable codes, and manufacturer recommendations.
Important Ordering Notes
