ASC Engineered Solutions 310046800 – Frequently Asked Questions
1) What do the three sizes on the 1-1/2 x 1-1/4 x 3/4 black malleable iron tee mean?
It's a reducing tee: the two run ends are 1-1/2 inch and 1-1/4 inch, and the branch outlet is 3/4 inch. All three openings are female pipe thread, so it takes male-threaded pipe nipples or threaded pipe ends on every port. Use it where a 1-1/2 inch line steps down to 1-1/4 inch and you need a 3/4 inch takeoff at the same point.
2) Is this tee UL Listed and FM Approved for fire sprinkler work?
It carries UL/FM recognition, so it can be used on fire protection piping where a UL Listed, FM Approved fitting is called for. It's a standard-weight black malleable iron fitting built to ASME B16.3, the usual choice for wet-system branch lines.
3) Can I use a black malleable iron tee on a domestic water line?
No. Black fittings like this one are for gas, fire protection, steam, air, and other non-potable service. Black iron has no protective coating and will rust in potable water. For water lines use galvanized malleable iron, copper, or CPVC instead.
4) Is this a standard weight or extra heavy fitting, and what pressure spec does it follow?
Standard weight (Class 150), rated per ASME B16.3. If your drawing calls for a Class 300 extra-heavy fitting, this is not the right part. For most gas and sprinkler branch piping, standard weight is what the spec calls out.
5) Will the dimensions match the malleable iron fittings already in my system?
They should. The fitting is made to ASME B16.3, which fixes center-to-end dimensions for threaded malleable iron fittings, so it drops into the same takeout as any other B16.3 standard weight tee of the same three sizes regardless of brand.
6) What grade of iron is this ASC tee made from?
Malleable iron to ASTM A-197, the standard material spec for cupola malleable iron threaded fittings. That grade is what gives the fitting its ductility, which is why malleable iron is used for threaded gas and sprinkler work rather than brittle cast iron.
7) How much does this reducing tee weigh for a materials takeoff?
1.08 lbs each. Handy if you're pricing freight or figuring hanger loads on a run with several of them.
8) What is the part number for the ASC 1-1/2 x 1-1/4 x 3/4 black tee?
ASC Engineered Solutions model 310046800. That's the reducing tee with 1-1/2 and 1-1/4 inch run ends and a 3/4 inch branch, black malleable iron, standard weight.
