ASC Engineered Solutions 310047808 – Frequently Asked Questions
1) What size openings does the ASC 1-1/2 x 3/4 x 1-1/2 black malleable iron tee have?
It's a reducing tee: the two run ends are 1-1/2 inch and the branch outlet is 3/4 inch. All three openings are female pipe thread (FPT), so 1-1/2 inch pipe threads into the run and 3/4 inch pipe threads into the branch. Use it where you need to pull a 3/4 inch takeoff off a 1-1/2 inch line without reducing the main.
2) Will this tee thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT taper thread spec, so it mates with ordinary threaded black steel pipe and standard NPT nipples. The fitting body follows ASME B16.3 for dimensions and pressure rating, so the face-to-center and thread engagement match any other standard malleable iron tee of the same size.
3) Is this tee acceptable for a fire sprinkler system?
It carries UL/FM approval, so it can be used on fire protection piping where the approval is what the AHJ is looking for. It's a standard-class (STD) black malleable iron fitting to ASME B16.3, which is the usual construction for threaded sprinkler branch lines.
4) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron is for non-potable service: gas, fire protection, compressed air, and black steel heating lines like steam or hydronic. Black fittings have no protective coating and will rust in water service. For potable water you want galvanized, brass, or copper instead.
5) What is the difference between standard and extra heavy malleable iron fittings, and which is this?
This is a standard (STD) class tee. Standard is the 150-class malleable iron fitting used for most gas, air, and fire protection work. Extra heavy (300 class) has thicker walls and a higher pressure rating and is specified where the drawing calls for it, typically on higher-pressure steam or process piping. If the spec on your job says extra heavy, this one won't satisfy it.
6) How much does the 1-1/2 x 3/4 x 1-1/2 black tee weigh for a shipment or hanger load count?
Each tee weighs 1.41 lbs. Worth counting if you're sizing hanger spacing on a long threaded run or estimating freight on a pallet of fittings.
