ASC Engineered Solutions 310051008 – Frequently Asked Questions
1) What are the three port sizes on the ASC 2 x 1-1/4 x 1-1/4 black malleable iron tee?
The run is 2 inch on one end and the other two openings are 1-1/4 inch, so it's a reducing tee that drops both the second run port and the branch down from 2 inch pipe. All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe nipples, not onto female ends.
2) Will this black malleable iron 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 any standard NPT male pipe end or nipple in the matching size. Use pipe dope or PTFE tape on the taper as usual.
3) Is this ASC malleable iron tee UL listed and FM approved for fire sprinkler work?
It carries UL/FM recognition, so it can be used on fire protection piping where a listed and approved fitting is required. It's a standard-weight (STD) class malleable iron fitting rated to ASME B16.3, which is the pressure class basis for the fitting.
4) Do I need a reducing bushing with this tee to go from 2 inch down to 1-1/4 inch?
No bushing needed. The reduction is built into the fitting itself, with the 2 inch port on one end and 1-1/4 inch on the other two openings. Bushing a straight 2 inch tee down adds two extra thread joints and takes up more space; a factory reducing tee like this keeps the assembly shorter and cuts leak paths.
5) Can I use a black malleable iron tee on a water line, or is it gas only?
Black malleable iron is the uncoated version and has no corrosion protection, so it's normally run on gas, fire sprinkler, compressed air, steam and similar dry or closed systems rather than open potable water, where galvanized or a non-ferrous fitting is the usual pick. This one is the black finish, ASTM A197 malleable iron.
6) Will this tee meet a spec calling for ASME B16.3 malleable iron threaded fittings?
Yes. Dimensions and pressure rating are both to ASME B16.3, the material is malleable iron to ASTM A197, and the threads are ASME B1.20.1. That's the standard three-part callout on most commercial and institutional piping specs for threaded black iron fittings.
7) Which ASC part number is the 2 x 1-1/4 x 1-1/4 black tee?
Order ASC Engineered Solutions part 310051008. It weighs 1.72 lbs, useful if you're pricing out freight or checking hanger loading on a run of them.
