Description
300# Extra Heavy Galvanized Malleable Iron Tee
300# extra heavy galvanized malleable iron tees create a 90-degree branch connection in a threaded piping system. The three female NPT openings provide a durable straight-through run with a perpendicular branch for demanding commercial, industrial, mechanical, fire-protection, maintenance, and repair applications where corrosion resistance and a galvanized finish are required.

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

Frequently Asked Questions
What is a 300# galvanized malleable iron tee used for?
It creates a 90-degree branch connection from the straight run of a compatible threaded piping system.
Does this tee have female threads on all three openings?
Yes. ASC Figure 3164 has female NPT threaded connections on both run openings and the branch opening.
Are all three openings the same nominal size?
Yes. This is an equal tee, so the run and branch openings are the same nominal pipe size.
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 sizes are available?
Available product variations range from 1/4" through 4" nominal pipe size.
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
- Select the required nominal pipe size before adding the product to your cart.
- This equal tee has female NPT threaded connections on all three openings.
- The selected variation determines the ASC item number, online selling price, estimated weight, and net cost.
- Confirm the nominal size and thread type of all three mating components before ordering.
- Confirm that an equal-size tee and 90-degree branch configuration are appropriate for the required piping layout.
- Confirm pressure, temperature, media compatibility, and application requirements before installation.
- Use an approved thread sealant suitable for the piping media and operating conditions.
- Avoid overtightening, which may damage the fitting or mating threads.
- Support connected piping properly to avoid excessive mechanical stress on the fitting.
- Installation should be completed by qualified personnel and comply with applicable codes and standards.
