ASC Engineered Solutions 310042007 – Frequently Asked Questions
1) Can I use a black malleable iron tee on a gas line?
Black malleable iron fittings are the standard choice for black iron gas piping and for steam and non-corrosive fluid service, which is what the black finish signals (uncoated, no zinc). Galvanized fittings are the ones used on water. This tee is black finish malleable iron to ASTM A-197 in standard (STD) pressure class per ASME B16.3. Confirm the application against your local gas code before installing.
2) Is this tee UL Listed and FM Approved for fire sprinkler work?
Yes, the ASC 3/4 x 3/4 x 1 black malleable iron tee carries UL/FM recognition, so it can be specified where a fire protection contractor or an inspector requires listed fittings on threaded sprinkler piping.
3) I need a reducing tee that takes 1 inch on the run and 3/4 inch on the branch. Is this the right one?
No. On this fitting the 1 inch opening is the branch, not the run, so it gives you 3/4 x 3/4 run with a 1 inch side outlet. For a 1 inch run with a 3/4 inch takeoff you want a 1 x 1 x 3/4 reducing tee instead. Malleable iron tee sizes are always read run, run, branch.
4) Does this fitting meet the ASME B16.3 spec called out on my drawing?
It does. Dimensions and pressure class both follow ASME B16.3, the standard for malleable iron threaded fittings, and it's a standard (STD, Class 150) strength fitting rather than extra heavy. Threads are ASME B1.20.1 and the casting is ASTM A-197 malleable iron.
5) Can I use this black tee on a potable water line?
Not a good choice. Black malleable iron is uncoated and will rust in wet water service; galvanized malleable iron or a copper/CPVC/PEX fitting is what belongs on potable water. Keep this one on black iron gas, steam, or air piping.
6) What is the ASC part number and weight for the 3/4 x 3/4 x 1 black tee?
The manufacturer part number is 310042007 and it weighs 0.62 lbs each, which matters if you're pricing out freight on a bulk order of fittings for a job.
