ASC Engineered Solutions 310029806 – Frequently Asked Questions
1) Are all three openings on the ASC 1/2 inch black malleable iron tee the same size?
Yes, it's a straight 1/2 inch tee. All three outlets are 1/2 inch female pipe thread, so there's no reducing branch. If you need to step the branch down or up, you'll want a reducing tee or a bushing in the branch.
2) Can I use this black iron tee on a fire sprinkler line?
It carries UL/FM approval, which is what an inspector looks for on sprinkler piping fittings. It is a standard weight (STD) malleable iron tee rated to ASME B16.3 for pressure. Confirm the pressure class required by your sprinkler design still fits a standard class 150 malleable fitting.
3) Is black malleable iron the right fitting for a water line, or should I use galvanized?
Black malleable iron is the gas and fire-protection fitting, not a potable water fitting. The black finish here has no zinc coating, so it corrodes in wet potable service. Use it on natural gas, propane, air, and sprinkler piping; go galvanized, copper, or CPVC for domestic water.
4) Does this 1/2 inch tee meet the ASME spec my drawing calls out for malleable iron fittings?
Dimensions and pressure rating are both to ASME B16.3, the malleable iron threaded fitting standard, with threads to ASME B1.20.1. The casting itself is ASTM A-197 malleable iron. That is the usual spec stack a mechanical drawing calls for on threaded black iron.
5) What does STD strength mean on this black iron tee, and do I need XH instead?
STD is the standard weight fitting, the common class used on gas, air, and sprinkler branch piping. Extra heavy (XH) fittings have thicker walls for higher pressure service. If your spec sheet calls for extra heavy or class 300, this standard weight tee is not the one to order.
6) What is the ASC part number for the 1/2 inch black malleable iron tee?
Order it as ASC Engineered Solutions MPN 310029806. That is the 1/2 x 1/2 x 1/2 inch standard weight black malleable iron tee with FPT ends.
