ASC Engineered Solutions 310520200 – Frequently Asked Questions
1) What size are the three openings on the ASC Engineered Solutions 310520200 black malleable iron tee?
It's a reducing tee: the two run ends are 3/4 inch and the branch outlet is 3/8 inch. All three openings are female pipe thread (FPT), so it takes male threaded pipe or nipples on every port. Use it where you need to pick off a small 3/8 inch branch, like a gauge, drain, or sensor tap, from a 3/4 inch line without adding a bushing.
2) What does XH mean on this ASC malleable iron tee, and how is it different from a standard fitting?
XH is extra heavy, meaning a thicker wall and a higher pressure rating than a standard (Class 150) malleable fitting of the same size. Pressure and dimensions both follow ASME B16.3. If your drawing calls for Class 300 or extra heavy black iron fittings, this is that class; a standard weight fitting is not a substitute.
3) Can I use this black iron tee on a fire sprinkler line?
It carries UL/FM approval, so it is acceptable for fire protection piping where UL Listed and FM Approved threaded fittings are specified. Confirm the job's own approval requirements with the AHJ, since sprinkler work is inspected against the approved submittal.
4) Is a black malleable iron tee OK for potable water?
No. Black malleable iron fittings are for gas, fire protection, steam, air, and non-potable service. The black finish here has no protective coating for water service; for potable lines use galvanized, copper, brass, or PEX fittings instead.
5) Do I need a bushing to land a 3/8 inch branch off a 3/4 inch black iron run?
Not with this fitting. The branch is cast at 3/8 inch FPT, so the reduction is built into the tee. That removes one threaded joint compared with running a 3/4 x 3/4 x 3/4 tee plus a 3/4 to 3/8 bushing, which matters where you are tight on space or want fewer potential leak points.
6) What grade of malleable iron is this tee made from?
The casting conforms to ASTM A-197, the standard for cupola malleable iron used in threaded pipe fittings. That is the material spec most commercial plumbing and gas submittals ask for on black iron fittings.
7) How much does one 3/4 x 3/4 x 3/8 extra heavy black tee weigh for a takeoff?
Each tee weighs 0.8 lbs. Handy if you are estimating hanger loads or freight on a box of fittings.
