ASC Engineered Solutions 310048608 – Frequently Asked Questions
1) Are the connections on this ASC black malleable iron tee threaded or do they need to be welded?
All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe ends with no welding. The threads are cut to ASME B1.20.1, the NPT standard, so it mates with any standard NPT-threaded steel or iron pipe nipple.
2) What size pipe does the run of this ASC reducing tee take?
The run is 1 inch on both ends, female threaded. The third opening is a different size, which is what makes it a reducing tee rather than a straight 1 inch tee, so match the branch size against your drawing before ordering.
3) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron fittings are for gas, air, steam, and closed-loop hydronic service, not domestic water, because the unplated iron corrodes in an aerated potable system. For water lines use a galvanized malleable fitting, copper, or CPVC. The black finish here is the standard black-coated malleable iron.
4) Is this fitting acceptable for a fire sprinkler branch line?
It carries a UL/FM listing, which is the approval fire protection inspectors look for on sprinkler piping components. It is standard weight malleable iron built to the ASME B16.3 dimensional and pressure-rating standard. Confirm the pressure class against your system design, since standard weight and extra heavy carry different ratings.
5) Will this ASC tee meet a spec calling out ASME B16.3 malleable iron fittings?
Yes. The tee is built to ASME B16.3 for dimensions and pressure rating, with the iron itself to ASTM A197 and the threads to ASME B1.20.1. That is the standard callout trio on commercial and industrial piping drawings for threaded malleable iron.
6) Is this standard weight or extra heavy malleable iron?
Standard weight. Standard weight (sometimes called Class 150) is the common choice for general threaded gas and hydronic work; if your spec calls for extra heavy or Class 300, this is not the fitting for it.
7) Do I need to order anything else to install this malleable iron tee?
The tee ships as the fitting only. Because all three ports are female threaded, you supply the male-threaded nipples or threaded pipe ends and a thread sealant or PTFE tape rated for your service (gas-rated sealant on fuel gas lines). No gaskets or unions are included.
8) How much does this 1 inch black malleable tee weigh for takeoff and shipping?
The fitting weighs 1.19 lbs each. Worth knowing when you are pricing a bulk run of threaded fittings or figuring hanger spacing on a filled line.
9) What is a reducing tee used for versus a straight tee and a bushing?
A reducing tee changes size at the branch in one fitting, so you get a single set of threaded joints instead of a straight tee plus a bushing or reducer. Fewer joints means fewer leak paths and less overall length, which matters in tight mechanical rooms. This one is a female-threaded malleable iron reducing tee with a 1 inch run.
