ASC Engineered Solutions 310525803 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions 2 x 2 x 3/4 black malleable iron tee take on each opening?
Run openings are 2 inch and the branch is 3/4 inch, so it's a reducing tee: full 2 inch flow straight through with a 3/4 inch takeoff for a drop, gauge, or smaller branch line. All three ends are female pipe thread (FPT), so they thread onto male-threaded pipe nipples or threaded pipe ends.
2) Will this black malleable iron tee thread onto standard NPT pipe?
Yes. The threads are made to ASME B1.20.1, which is the standard NPT pipe thread spec, so it mates with any standard NPT male pipe end or nipple. Use pipe dope or PTFE tape on the male threads to seal, since NPT is a tapered thread joint and seals on thread engagement.
3) What does XH mean on a malleable iron fitting, and is it stronger than a standard fitting?
XH is extra heavy, meaning thicker walls and a higher pressure rating than a standard (Class 150) malleable fitting of the same size. Pressure ratings follow ASME B16.3, which is the rating standard for malleable iron threaded fittings. If your drawing calls out Class 300 or extra heavy malleable, this is the class you want; a standard-weight tee is not a substitute.
4) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron is for non-potable service, typically natural gas, fuel oil, air, steam, and fire protection piping. The black finish has no corrosion protection against water, so for potable water use galvanized malleable iron, copper, or a comparable approved material instead.
5) What is this malleable iron tee actually made of, and does it meet a material spec I can submit?
The casting is malleable iron produced to ASTM A-197, with dimensions to ASME B16.3. Those two callouts plus the ASME B1.20.1 thread spec are what a submittal or spec section for threaded malleable iron fittings normally asks for.
6) Do I need a reducing bushing to get from 2 inch down to 3/4 inch with this fitting?
No bushing needed. The reduction is built into the tee: the 3/4 inch branch is cast as a female threaded outlet, so you thread a 3/4 inch nipple straight in. That's one less joint than running a full-size 2 x 2 x 2 tee with a 2 x 3/4 bushing, which matters where a bushing would be restricted by code or by the sprinkler approval.
7) What is the part number for the ASC Engineered Solutions 2 x 2 x 3/4 extra heavy black tee?
The manufacturer part number is 310525803, from ASC Engineered Solutions. Specify it by the full description as well when ordering, 2 x 2 x 3/4 extra heavy black malleable iron tee, since standard-weight tees in the same size are easy to mix up on a pick list.
