ASC Engineered Solutions 310038203 – Frequently Asked Questions
1) What do the three sizes on a 3/4 x 3/4 x 1/2 black malleable iron tee mean?
The two run ends are both 3/4 inch and the branch (outlet) is 1/2 inch. So the tee carries a 3/4 inch line straight through and drops a 1/2 inch takeoff off the side, which is how you pick up a smaller branch without adding a separate bushing and coupling.
2) Are all three openings on this ASC Engineered Solutions tee female threaded?
All three ports are FPT, female pipe thread, so male-threaded pipe nipples or threaded pipe ends screw into every opening. Threads are cut to ASME B1.20.1 (NPT), which means standard black or galvanized threaded pipe and standard NPT nipples mate with it.
3) Can I use a black malleable iron tee on a fire sprinkler line?
This 3/4 x 3/4 x 1/2 tee is UL/FM rated, so it is acceptable for use on fire protection piping where UL Listed and FM Approved fittings are required. It is standard pattern malleable iron built to ASME B16.3 for both dimensions and pressure rating.
4) Is a black iron tee OK for a gas line, or do I need galvanized?
Black finish malleable iron is the conventional choice for natural gas and propane piping, and for closed-loop hydronic and steam work. Galvanized is used on the water side. This fitting is black malleable iron to ASTM A-197 with NPT threads, so it lands in the black iron family, not the potable water one. Local gas code governs the final call.
5) Will this tee interchange with another brand's 150 lb malleable iron tee?
Dimensionally, yes. The tee is made to ASME B16.3, the standard that fixes malleable iron fitting center-to-end dimensions and pressure class, and threads to ASME B1.20.1. Any standard pattern 3/4 x 3/4 x 1/2 malleable tee built to the same standards takes the same nipple lengths and drops into the same spot in an existing run.
6) Is this a standard or extra heavy malleable iron tee?
Standard pattern (STD), which is the 150 class malleable iron fitting used on the large majority of threaded gas, hydronic and general service piping. If a drawing calls for extra heavy or 300 class, this is not that fitting and you need the XH pattern instead.
7) Do I need a reducing bushing with this tee to pick up a 1/2 inch branch?
No. The 1/2 inch outlet is cast into the tee, so a 1/2 inch nipple threads straight into the branch. Using a full 3/4 tee plus a 3/4 x 1/2 bushing would add a joint and take up more space in the same run. All three ports are female NPT.
8) What is the part number and weight on the ASC 3/4 x 3/4 x 1/2 black tee?
The manufacturer part number is 310038203 and the fitting weighs 0.47 lbs each, which is the number to use when you are figuring hanger spacing or freight on a bulk fitting order.
