ASC Engineered Solutions 311053003 – Frequently Asked Questions
1) What size branch does the ASC Engineered Solutions 2-1/2 x 2-1/2 x 1 galvanized malleable iron tee have?
It's a reducing tee: the run is 2-1/2 inch on both ends and the branch outlet is 1 inch. All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe nipples on every port. Use it where you need to pull a 1 inch takeoff off a 2-1/2 inch line without adding a bushing.
2) Is this tee UL Listed and FM Approved for a fire sprinkler line?
It carries UL/FM recognition, so it can be specified on fire protection piping where a listed and approved fitting is required. It is a standard (STD) class malleable iron tee rated per ASME B16.3.
3) Are the threads on this malleable iron tee standard NPT?
Yes. The threads are cut to ASME B1.20.1, which is the standard American taper pipe thread spec, so the fitting mates with ordinary NPT-threaded steel or galvanized pipe and nipples. Overall dimensions follow ASME B16.3, so it drops into a layout designed around standard malleable iron fittings.
4) Is this galvanized tee OK for an outdoor or wet location?
The galvanizing is done to ASTM A-153, the hot-dip spec for hardware, which is what you want for exposed, damp, or corrosive service. The body is malleable iron to ASTM A-197. Pair it with galvanized pipe rather than black pipe so you aren't mixing coated and uncoated steel in the same run.
5) Do I need a bushing or reducer with this tee to get down to 1 inch?
No. The 1 inch reduction is built into the branch, so you thread a 1 inch male nipple straight into the outlet. Adding a bushing would only be needed if your takeoff is smaller than 1 inch.
6) Can I use this on a compressed air or water line, not just sprinkler?
Yes. It's a general purpose threaded malleable iron fitting rated to ASME B16.3 in standard class, commonly used on water, air, and low pressure service as well as fire protection. Because all three ends are female NPT, you'll need male-threaded nipples or pipe ends at each connection, and the usual pipe dope or PTFE tape on the taper threads.
7) What is the ASC part number for this galvanized reducing tee?
The manufacturer part number is 311053003, an ASC Engineered Solutions galvanized malleable iron tee, 2-1/2 x 2-1/2 x 1.
