ASC Engineered Solutions 311048409 – Frequently Asked Questions
1) What are the port sizes on the ASC Engineered Solutions galvanized malleable iron reducing tee, model 311048409?
It's a reducing tee with two 1-1/4 inch runs and a 1-1/2 inch branch. All three openings are female pipe thread (FPT), so it takes male threaded pipe ends on every port. Note the branch is the larger opening here, which is the opposite of most reducing tees, so check your layout before you cut pipe.
2) Will this galvanized tee thread onto standard NPT pipe and nipples?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT taper thread spec, so it mates with any standard threaded steel or brass nipple of the matching size. Use pipe dope or PTFE tape on the taper for a seal.
3) Is this tee approved for fire sprinkler piping?
The fitting carries UL/FM approval, so it can be used in fire protection piping where the AHJ requires listed fittings. It's a standard weight galvanized malleable iron tee dimensioned to ASME B16.3, which is the fitting standard sprinkler contractors work to.
4) Galvanized or black malleable iron tee for my job?
Galvanized is what you want for wet systems, dry sprinkler lines, compressed air with moisture, and anywhere corrosion is a concern. This one is hot dip galvanized to ASTM A-153 over malleable iron made to ASTM A-197. Black malleable is the usual choice for natural gas and dry indoor service. Don't run galvanized where the spec calls for black on gas piping without checking local code.
5) Can I use a 1-1/4 x 1-1/4 x 1-1/2 tee to branch up to a larger line?
That's exactly what this fitting does. The run stays at 1-1/4 inch through both ends and the branch opens up to 1-1/2 inch, so you can take a larger outlet off a 1-1/4 inch run without changing the main. It weighs 1.4 lbs, light enough to support on standard hangers at the branch.
6) Do I need any gaskets or extra parts to install this malleable iron tee?
No gaskets or inserts. All three ports are tapered female pipe thread, so the seal is made on the threads with pipe joint compound or PTFE tape. You supply the nipples or threaded pipe ends; nothing ships with the fitting.
