ASC Engineered Solutions 310520002 – Frequently Asked Questions
1) What are the three outlet sizes on the ASC Engineered Solutions 310520002 black malleable iron tee?
It's a reducing tee: two 3/4 inch openings on the run and a 1/2 inch branch. All three ends are female pipe thread (FPT), so it takes male-threaded pipe nipples or male adapters on every port. Use it where you're running 3/4 inch line and dropping to a 1/2 inch takeoff.
2) What does the XH rating mean on this 3/4 x 3/4 x 1/2 malleable iron tee?
XH means extra heavy: a thicker wall and a higher pressure rating than a standard-weight (150) malleable fitting of the same size. Pressure ratings follow ASME B16.3, and the fitting is made to ASTM A-197 malleable iron. If your drawing calls for 300 class black malleable, XH is the fitting you want; a standard 150 tee is not a substitute.
3) Is this black malleable tee UL listed and FM approved for fire sprinkler work?
Yes, the 310520002 extra heavy black tee carries UL/FM recognition, so it can be used on fire protection piping where UL Listed and FM Approved fittings are specified. That, plus the extra heavy wall, is why this one shows up on sprinkler and standpipe jobs rather than a standard-weight fitting.
4) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron is for non-potable service, typically natural gas, fuel oil, compressed air, fire protection, and steam or hydronic lines. The black finish is a mill coating, not a corrosion barrier for wet potable use. For domestic water, run galvanized or a copper/PEX system instead.
5) Will this tee match the laying length of the fitting I'm replacing?
It's built to ASME B16.3, the dimensional standard for threaded malleable iron fittings, so center-to-end dimensions match any other B16.3 3/4 x 3/4 x 1/2 tee. Swapping it into an existing threaded run won't change your nipple lengths.
6) How much does one of these 3/4 x 3/4 x 1/2 extra heavy tees weigh?
About 0.9 lbs each. Worth knowing if you're figuring hanger spacing and total load on a long threaded run, since extra heavy fittings add up faster than standard weight.
