ASC Engineered Solutions 310056809 – Frequently Asked Questions
1) What size pipe does the ASC 4 x 4 x 2-1/2 black malleable iron tee take on each opening?
Run openings are both 4 inch and the branch is 2-1/2 inch, so it carries a 4 inch line straight through and drops a reduced 2-1/2 inch takeoff. All three openings are female pipe thread (FPT), so they thread onto male-threaded pipe ends or nipples.
2) Will this black malleable iron tee thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, which is the NPT standard, so it mates with ordinary NPT-threaded steel pipe and nipples. Dope or tape the male threads as usual.
3) Is this tee acceptable for a fire sprinkler main?
It carries a UL/FM listing, which is what an AHJ looks for on fire protection piping. With a 4 inch run and a 2-1/2 inch branch it is the fitting you'd use to pull a 2-1/2 inch riser, cross main or hose valve connection off a 4 inch main. Black finish is the usual choice for wet sprinkler and steel pipe service rather than galvanized.
4) What pressure class is this ASC malleable iron tee, and what standard does it meet?
It's a standard (STD) class malleable iron fitting rated per ASME B16.3, with dimensions to that same standard and material to ASTM A-197. Because it's dimensionally B16.3, it interchanges with any other Class 150 malleable iron fitting of the same size from another maker.
5) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron is for non-potable service, typically fire protection, steam, natural gas and compressed air. For potable water use galvanized malleable iron, brass, or copper fittings instead, since bare black iron will rust in domestic water.
6) Is a reducing tee like this the right way to branch a 2-1/2 inch line off a 4 inch main, or should I use a full-size tee and a bushing?
The reducing tee is the cleaner way. The 2-1/2 inch branch is cast into the body, so you make one joint instead of stacking a 4 x 4 x 4 tee with a 4 x 2-1/2 bushing, and you avoid the extra leak path and the pressure-drop of a bushed outlet. Many fire protection AHJs also dislike bushings in listed piping; this fitting is UL/FM listed as supplied.
7) What part number do I order for the ASC 4 x 4 x 2-1/2 black malleable iron tee?
Order ASC Engineered Solutions part 310056809. Threads are FPT on all three openings, so plan on male-threaded nipples or field-cut pipe threads at each connection; no gaskets or bolts are involved.
