ASC Engineered Solutions 310046206 – Frequently Asked Questions
1) What size are the three openings on the ASC Engineered Solutions 1-1/2 x 1-1/4 x 1-1/2 black malleable iron tee?
The run is 1-1/2 inch on both ends and the branch outlet reduces to 1-1/4 inch. All three openings are female pipe thread, so it drops into a 1-1/2 inch run where you need to take a 1-1/4 inch branch off the side without adding a separate bushing.
2) Will this black malleable iron tee thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, the NPT standard, so it mates with any standard threaded steel or iron pipe and nipples of the matching size. All three ports are female, so you thread male pipe ends or nipples into the fitting.
3) Can I use this tee on a fire sprinkler line?
It carries UL/FM approval, which is what an AHJ looks for on fire protection piping. It is a standard weight black malleable iron tee built to ASME B16.3. Confirm the size and configuration match the sprinkler drawing before it goes in.
4) Is a black malleable iron tee the right choice for a water line, or should I use galvanized?
Black fittings are for gas, fire sprinkler, steam, and closed-loop hydronic work. The finish on this tee is black with no zinc coating, so it will rust in an open, aerated potable or wet-service line. For domestic water or damp exposure, go with the galvanized version of the same malleable iron tee.
5) Does this ASC tee meet spec for a commercial job calling out ASME B16.3 malleable iron fittings?
It does. Dimensions and pressure rating both follow ASME B16.3, the material is malleable iron to ASTM A-197, and threads are ASME B1.20.1. That is the standard call-out trio on most commercial and institutional threaded fitting specs, and it is a standard (STD) weight Class 150 style fitting rather than an extra heavy one.
6) Do I need a bushing or reducer to take a 1-1/4 inch branch off my 1-1/2 inch line?
Not with this fitting. The branch is already reduced to 1-1/4 inch as part of the casting, so you thread your 1-1/4 inch nipple straight into the outlet. Using a full 1-1/2 inch tee plus a bushing adds two more thread joints and another leak path.
7) What is the manufacturer part number for this reducing tee?
ASC Engineered Solutions part number 310046206, a 1-1/2 x 1-1/4 x 1-1/2 black malleable iron tee. Use that number when matching it against a submittal or reordering to keep the fitting consistent across a building.
8) How much does this 1-1/2 inch malleable iron tee weigh?
About 1.5 lbs each. Worth knowing if you are pricing out a hanger and support layout or estimating a bulk order for a large threaded pipe run.
