Description
300# Extra Heavy Black Malleable Iron Reducing Tee
300# extra heavy black malleable iron reducing tees create a 90-degree branch connection where the branch outlet is smaller than the two equal-size run openings. Three female NPT connections allow compatible male-threaded pipe, pipe nipples, valves, or fittings to be joined in demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications.
Select the required configuration from the product options above. Sizes are read end x end x middle. The selected variation determines the ASC item number, UPC, online selling price, weight, net cost, and other configuration-specific product information.

How a Reducing Tee Works
A reducing tee has two aligned female NPT openings that form the main run and a smaller female NPT opening positioned at 90 degrees to create the branch. The fitting allows the main line to continue at one nominal size while transitioning the branch to a smaller nominal pipe size.
How to Read the Size
Reducing tee sizes are read end x end x middle. For example, a 2" x 2" x 1" reducing tee has two 2" run openings and one 1" branch opening located in the middle.

Frequently Asked Questions
What is a 300# black malleable iron reducing tee used for?
It creates a 90-degree branch connection where the branch line is smaller than the two equal-size run openings.
How are reducing tee sizes read?
Sizes are read end x end x middle. The first two dimensions identify the equal-size run openings, and the third dimension identifies the reduced branch opening.
Does this tee have female threads on all three openings?
Yes. All three openings have female NPT threads for connection to compatible male-threaded components.
What pressure class is this fitting?
This fitting is manufactured as a 300# / Class 300 extra heavy threaded malleable iron fitting.
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.
