ASC Engineered Solutions 311047401 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 311047401 galvanized malleable iron tee?
It's a reducing tee with 1-1/2 inch, 1 inch, and 1-1/4 inch openings. All three ends are female pipe thread (FPT), so it takes male-threaded pipe or nipples in each port. Threads follow ASME B1.20.1 (NPT), so it mates with standard American taper pipe thread.
2) Is this galvanized malleable iron tee UL listed and FM approved for fire sprinkler work?
Yes. The 311047401 reducing tee carries UL/FM recognition, which is what an inspector looks for on a wet or dry sprinkler branch line. It's standard weight malleable iron with a hot-dip galvanized finish per ASTM A-153, which is the finish normally specified for dry-pipe and pre-action systems where corrosion is a concern.
3) Can I use a galvanized malleable iron tee on a potable water line?
Galvanized malleable iron fittings like this 1-1/2 x 1 x 1-1/4 tee are the traditional match for galvanized steel pipe and are commonly used on water, air, and fire protection lines. Threaded joints are made up with an approved sealant or PTFE tape. If your job requires a certified lead-free potable water fitting, confirm the specific approval your jurisdiction demands before you install.
4) Is this tee dimensionally interchangeable with other brands of malleable iron fittings?
Yes. The tee is made to ASME B16.3, which governs both the center-to-end dimensions and the pressure class for malleable iron threaded fittings. Any standard-class B16.3 fitting of the same sizes will lay out the same on your piping, so you can mix it with existing galvanized fittings without redoing takeouts.
5) Is this a standard weight or extra heavy fitting?
Standard weight (Class 150). If your spec calls for extra heavy, Class 300 malleable iron, this one won't satisfy it. The body is malleable iron to ASTM A-197 with the pressure rating set by ASME B16.3.
6) How much does this reducing tee weigh for takeoff and hanger sizing?
1.44 lbs each. Useful when you're totaling fitting weight on a hung branch line or figuring shipping on a bulk MRO order.
7) What part number do I order for the ASC 1-1/2 x 1 x 1-1/4 galvanized tee?
ASC Engineered Solutions part number 311047401. That's the galvanized malleable iron reducing tee with all three ends female threaded.
