ASC Engineered Solutions 310047204 – Frequently Asked Questions
1) What size are the three openings on the ASC 1-1/2 x 1 x 1-1/2 black malleable iron tee?
The run of this ASC Engineered Solutions tee is 1-1/2 inch on both ends, and the branch outlet is reduced to 1 inch. All three openings are female pipe thread (FPT), so it threads onto male pipe ends or nipples. Use it where you need to pull a 1 inch branch off a 1-1/2 inch line without adding a separate bushing.
2) Will this malleable iron tee thread onto standard black steel pipe?
Yes. The threads are cut to ASME B1.20.1, which is standard NPT, so it mates with any NPT-threaded black steel pipe or nipple in the matching size. Thread sealant or PTFE tape on the male threads as usual.
3) Is this black iron tee approved for fire sprinkler piping?
It carries UL/FM approval, so it is acceptable for fire protection piping where UL Listed and FM Approved fittings are specified. It is a standard-pattern (STD) malleable iron fitting made to ASME B16.3 for both dimensions and pressure rating.
4) Can I use a black malleable iron tee on a domestic water line?
No. Black malleable iron is for gas, fire protection, and other dry or non-potable service. The black finish has no corrosion protection against water, so for potable water you want galvanized malleable iron or a copper/brass fitting instead. This tee is black finish malleable iron.
5) What is the difference between a standard and extra heavy malleable iron tee, and which is this one?
This ASC tee is standard weight, marked STD. Standard pattern covers the common 150-class malleable iron fittings built to ASME B16.3. Extra heavy (300 class) fittings have thicker walls and a higher pressure rating and are ordered separately when the spec calls for them, so if your drawing says extra heavy, this is not the fitting.
6) Do I need a reducing bushing with this 1-1/2 x 1 x 1-1/2 tee?
No bushing needed for a 1 inch branch. The outlet is already cast at 1 inch FPT, so a 1 inch nipple or pipe threads straight in. You would only add a bushing if you were branching down to something smaller than 1 inch. Nothing else ships with the fitting.
7) What grade of iron is this ASC tee cast from?
The casting meets ASTM A-197, the malleable iron specification used for threaded pipe fittings. That is what gives the fitting its ductility compared with a plain cast iron fitting, which is why malleable iron is the material called out for threaded gas and sprinkler work.
8) How do I order the right ASC reducing tee by part number?
This one is ASC Engineered Solutions part 310047204, the 1-1/2 x 1 x 1-1/2 black malleable iron tee. It weighs about 1.5 lbs each, which is worth knowing if you are pricing freight on a full box for a job.
