ASC Engineered Solutions 311041404 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions galvanized malleable iron reducing tee, and which port is which?
It's a 1 x 1/2 x 3/4 reducing tee: the run is 1 inch, the second port is 1/2 inch, and the branch outlet size is 3/4 inch. All three openings are female pipe thread (FPT), so it takes male threaded pipe or nipples on every side. Reducing tees are read in that order, so you're getting one 1 inch, one 1/2 inch, and one 3/4 inch opening in a single fitting instead of a straight tee plus bushings.
2) Will this galvanized malleable iron tee thread onto standard black or galvanized steel pipe?
Yes. The threads are cut to ASME B1.20.1, which is standard NPT taper pipe thread, so it mates with any NPT male pipe end or nipple in the matching size. Dimensions follow ASME B16.3, the malleable iron threaded fitting standard, so the take-off and center-to-end geometry matches other B16.3 fittings you're already running.
3) Is this ASC tee UL listed and FM approved for a fire sprinkler line?
Yes, the 1 x 1/2 x 3/4 galvanized malleable iron tee carries UL/FM recognition, which is what an inspector looks for on fire protection piping. It's a standard (STD) pressure class fitting rated per ASME B16.3.
4) Is a galvanized malleable iron tee OK for a wet or outdoor line, or should I use black iron?
Galvanized is the corrosion-resistant choice here. The coating is hot dip galvanizing to ASTM A-153, which is the spec for hardware dipped after fabrication, so the threads and body are both coated. That's what you want on water service, outdoor runs, and wet sprinkler piping. Black malleable iron is the usual pick for dry gas and dry sprinkler systems instead.
5) Do I need a bushing to land a 3/4 inch branch off a 1 inch line?
No, not with this fitting. The 1 x 1/2 x 3/4 tee already has the reduction built in, so you get a 3/4 inch branch and a 1/2 inch port off a 1 inch run without stacking bushings. Fewer joints means fewer places to leak and less make-up length to account for in the run.
