ASC Engineered Solutions 311049209 – Frequently Asked Questions
1) What do the three sizes on a 2 x 2 x 1 galvanized malleable iron tee mean?
Two of the openings are 2 inch and the branch is 1 inch. So the run stays 2 inch straight through and you tap a 1 inch branch off the side. All three openings are female pipe thread (FPT), so pipe or nipples thread into the fitting, not over it.
2) Will this galvanized 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 ordinary threaded steel or galvanized pipe and nipples in the matching sizes. Use pipe dope or PTFE tape on the male threads.
3) Is this malleable iron tee acceptable for a fire sprinkler line?
It carries a UL/FM listing, so it is acceptable where UL Listed or FM Approved threaded fittings are called for, including sprinkler piping. Dimensions and pressure class follow ASME B16.3 in standard (STD) weight.
4) Should I use a galvanized malleable iron tee or a black iron tee?
Galvanized is the one to use on wet lines, potable-adjacent service, outdoor runs, and damp mechanical rooms, because the hot-dip zinc coating to ASTM A-153 resists corrosion. Black malleable iron is the usual pick for gas piping and dry sprinkler-free interior work. The body material is the same malleable iron either way.
5) Will a 2 x 2 x 1 tee interchange with another brand's malleable iron tee on the same run?
Yes, as long as the other fitting is also ASME B16.3 malleable iron in the same size and class. B16.3 fixes the center-to-end dimensions, so lay length matches and your nipples stay the same. The threads are B1.20.1 NPT on both.
6) What material spec does this tee meet, and does it matter for submittals?
The casting meets ASTM A-197 malleable iron and the zinc coating meets ASTM A-153, with dimensions and pressure rating to ASME B16.3 and threads to ASME B1.20.1. That set of four is normally what a mechanical submittal for threaded malleable iron fittings asks for. Manufacturer part number is 311049209.
7) Do I need a bushing to get down to the 1 inch branch?
No. The branch is already a 1 inch female thread, so a 1 inch nipple or pipe threads straight in. Using a 2 x 2 x 2 tee with a 2 x 1 bushing would do the same job but adds a joint and a leak path.
8) How heavy is a 2 x 2 x 1 galvanized malleable tee for shipping or overhead support?
About 2 lbs each. Light enough that a run of these on threaded rod hangers adds little load, but plan hanger spacing around the filled pipe weight, not the fitting.
