ASC Engineered Solutions 2X3/4X2 BLK MI TEE

It's a reducing tee: both run ports are 2 inch and the branch (outlet) is 3/4 inch. All three are female pipe thread. So you keep a full 2 inch run and tap off 3/4 inch for a drop, gauge, drain, or branch line without adding a bushing.

Yes. All three openings are FPT cut to ASME B1.20.1, which is standard NPT taper thread, so it mates with any threaded steel or black iron pipe nipple of the matching size. Use pipe dope or PTFE tape on the male threads.

It carries UL/FM approval, which is what an inspector looks for on sprinkler piping. It's a standard (STD) class malleable iron fitting built to ASME B16.3, the dimensional and pressure standard for threaded malleable iron fittings.

No. Black malleable iron is for gas, fire protection, steam, and dry service, not potable water, because the unlined black finish corrodes in wet service. For water you want galvanized malleable iron, copper, or CPVC instead. This tee's black finish tells you its intended service right away.

The reducing tee puts the 3/4 inch branch in the casting itself, so it's one joint instead of two and it takes up less length on the run. A 2 x 2 x 2 tee plus a 2 x 3/4 bushing gets you to the same size but adds a leak path and extra takeout. On UL/FM sprinkler work the single reducing tee is also the cleaner inspection item, and this one is UL/FM approved.

Orientation matters only in the sense that the 3/4 inch opening is the branch and the two 2 inch openings are the run. There's no flow direction to the casting itself, so thread the run into your 2 inch line and point the 3/4 inch branch wherever the drop or takeoff goes.

The manufacturer part number is 310051404 from ASC Engineered Solutions. That's the number to quote when matching an existing submittal or restocking a sprinkler or gas fitting bin.

The fitting weighs 2 lbs. Light enough to thread up in place on an overhead run without a second set of hands, but worth accounting for when you're hanging a long threaded 2 inch line.
