ASC Engineered Solutions 310039805 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions 1 x 1 x 3/4 black malleable iron tee take on each opening?
Two runs at 1 inch and a reducing branch at 3/4 inch. All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe ends on the run and gives you a 3/4 inch takeoff without adding a bushing.
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 NPT standard, so it mates with any standard NPT-threaded steel or black iron pipe and with NPT nipples. Use pipe dope or PTFE tape on the male threads as usual.
3) Black iron or galvanized tee, which do I use?
This one is black finish malleable iron, which is the usual choice for natural gas, propane, fire sprinkler, steam, and closed-loop hydronic piping. It's not the right pick for potable water or wet exposed outdoor runs, where corrosion resistance matters and a galvanized malleable fitting is used instead.
4) What is the pressure class on this 1 inch malleable iron tee?
It is a standard (STD) weight fitting rated per ASME B16.3, the class-based pressure standard for threaded malleable iron fittings. If your drawing calls for extra heavy, this one won't meet it, you need a 300-class fitting.
5) Does this tee meet spec for a commercial job that calls out ASTM A197 malleable iron?
Yes, the casting is made to ASTM A-197, and the dimensions follow ASME B16.3. Between those two callouts plus the B1.20.1 threads, it satisfies the usual mechanical spec language for threaded black malleable iron fittings.
6) How much does this tee weigh for takeoff and hanger loading?
0.82 lbs each. Useful if you are totaling fitting weight on a long overhead run or sizing support spacing.
