ASC Engineered Solutions 310517800 – Frequently Asked Questions
1) What size and connection type are the three openings on the ASC Engineered Solutions black malleable iron tee?
All three openings are 4 inch female pipe thread (FPT), so it's a straight run-and-branch tee with no reduction. Threads are cut to ASME B1.20.1, the NPT standard, so it mates with standard 4 inch threaded black steel pipe and nipples.
2) Can a black malleable iron tee be used on a water supply or underground line?
No. Black fittings like this one are for dry service such as gas, fire sprinkler, air, and steam lines. The finish is black, not galvanized, so it has no zinc coating to resist corrosion from potable water or buried, wet conditions. Use a galvanized malleable iron or an approved corrosion-resistant fitting for those applications.
3) What material spec does this ASC 4 inch tee meet, and does it match what my drawing calls out?
The casting is malleable iron to ASTM A-197, with dimensions to ASME B16.3. Those two callouts together are the usual specification line for a Class 150 style threaded malleable iron fitting, so if your drawing lists ASTM A197 / ASME B16.3 threaded fittings, this meets it.
4) Do I need a reducing tee if my branch is smaller than 4 inch?
Yes. This fitting is 4 x 4 x 4, all three ports the same size, so it cannot take a smaller branch directly. Either order a reducing tee in the sizes you need, or bush the 4 inch branch down with a threaded reducer bushing, checking first that your specification allows bushings on that service.
5) Does this tee need welding or can it be threaded up in the field?
It's a threaded fitting, female NPT on all three ports, so it makes up with pipe dope or PTFE tape and a pipe wrench. No welding, no grooving tool, no special press jaws. That makes it workable for a repair or tie-in where hot work permits are a problem.
