ASC Engineered Solutions 310044201 – Frequently Asked Questions
1) What do the three sizes on a 1-1/4 x 3/4 x 1 black malleable iron tee mean?
It's a reducing tee with three different female threaded openings: 1-1/4 inch on the run, 3/4 inch on the other run end, and 1 inch on the branch. All three are FPT, so each one takes male threaded pipe or a male nipple. If you need all three ports the same, this is the wrong fitting - you want a straight tee.
2) Will this ASC reducing tee thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT pipe thread spec, so it mates with ordinary black or galvanized threaded steel pipe and standard nipples. Use pipe dope or PTFE tape on the male threads as usual.
3) Can I use a black malleable iron tee on a water line?
Black malleable iron is meant for gas, air, steam, and fire protection piping, not potable water - black fittings are uncoated and will rust in a wet service. For water, use galvanized malleable iron, copper, or CPVC instead. The black finish here is the standard uncoated mill finish.
4) Is this ASC malleable iron tee UL Listed and FM Approved for sprinkler work?
Yes, the fitting carries UL/FM recognition, so it can go into fire protection piping where the AHJ requires listed fittings. It's a standard weight (STD) class fitting rated per ASME B16.3.
5) What pressure class is this standard weight malleable iron tee?
It's a standard weight (STD) fitting, with both its dimensions and pressure rating governed by ASME B16.3. If your drawing calls for 300 lb extra heavy malleable iron, this STD fitting won't meet that spec - order the 300 class version instead.
6) Will this tee lay out the same as any other brand's 1-1/4 x 3/4 x 1 malleable tee?
It should. Center-to-end dimensions are built to ASME B16.3, which is the dimensional standard every malleable iron fitting manufacturer works to, so it drops into the same takeout as a same-size fitting from another maker. That matters when you're replacing one fitting in an existing threaded assembly and can't move the pipe.
7) What material spec is this ASC tee made to?
The casting is ASTM A-197, the standard for cupola malleable iron used in threaded pipe fittings. If a submittal asks for the material spec on the fitting schedule, that's the line to cite, along with ASME B16.3 for dimensions and pressure class.
8) How much does one 1-1/4 x 3/4 x 1 black malleable tee weigh?
About 0.91 lbs each. Useful if you're figuring hanger spacing or total weight on a large fitting order.
