ASC Engineered Solutions 311050603 – Frequently Asked Questions
1) What are the three outlet sizes on the ASC Engineered Solutions galvanized malleable iron reducing tee, model 311050603?
It's a 2 x 1-1/4 x 2 reducing tee: the two run ends are 2 inch and the branch is 1-1/4 inch. All three openings are female pipe thread. So it carries a 2 inch line straight through and takes a 1-1/4 inch branch off the side, which is what you want when you're dropping a smaller takeoff off a 2 inch main without adding a bushing.
2) Will this galvanized tee thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, the NPT standard, so it mates with any standard threaded steel or galvanized pipe and with NPT male nipples. All three ends are female, so you'll need male threaded pipe or nipples going into each opening.
3) Is this ASC malleable iron tee approved for fire sprinkler piping?
It carries UL/FM approval, so it's acceptable for fire protection piping as well as general service. It's a standard-weight (STD) fitting rated to ASME B16.3, which is the class standard for threaded malleable iron fittings.
4) Galvanized or black malleable iron tee, which one do I use?
This one is hot dip galvanized to ASTM A-153, which is the corrosion protection you want for wet service, damp mechanical rooms, exterior runs, and water lines. Black malleable iron is the usual choice for dry systems and gas piping. Don't mix the two on the same run if corrosion is the reason you went galvanized.
5) What material and spec is this 2 inch reducing tee made to?
Malleable iron per ASTM A-197, with dimensions per ASME B16.3. If your drawing calls for threaded malleable iron fittings to B16.3 with A-197 castings, this meets that callout. Weight is 2.25 lbs per fitting.
6) Can I use this tee if my branch line is 2 inch, not 1-1/4 inch?
No. The branch outlet on this fitting is fixed at 1-1/4 inch while the run is 2 inch. For a full 2 inch branch you need a straight 2 x 2 x 2 tee. Reducing the branch with a bushing in a straight tee is the alternative, but a reducing tee like this one keeps the joint count down.
7) Does this fitting need sealant, and what do I install it with?
The tee ships as a bare fitting only, no nipples, pipe, or sealant. Because all three ends are tapered female NPT, you'll thread male pipe ends in with pipe dope or PTFE tape rated for the service, and back the fitting with a wrench on the run when you tighten the branch.
