ASC Engineered Solutions 311047203 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 311047203 galvanized malleable iron tee?
It's a reducing tee: the two run ends are 1-1/2 inch and the branch (center outlet) is 1 inch. All three openings are female pipe thread, so it takes male-threaded pipe or nipples on every port. Use it where you're pulling a 1 inch branch off a 1-1/2 inch run without adding a separate bushing.
2) Will this galvanized tee thread onto standard black or galvanized steel pipe?
Yes. The threads are cut to ASME B1.20.1, which is standard NPT, so it mates with any NPT male-threaded steel pipe or nipple in the matching size. Dimensions follow ASME B16.3, so the fitting's face-to-center and overall geometry match any other standard malleable iron tee of the same sizes.
3) Is this tee approved for fire sprinkler piping?
It carries UL/FM approval, so it can be used on fire protection piping where a listed fitting is required. It's standard weight (STD) malleable iron with pressure ratings per ASME B16.3. For the mechanical contractor, that means one fitting works for both the sprinkler branch and general service lines.
4) Can this fitting be used on wet or outdoor lines, or is it for dry service only?
The hot-dip galvanized coating is applied to ASTM A-153, the standard for galvanizing on threaded hardware, which is what you want on wet systems, outdoor runs, and damp mechanical rooms. The body itself is malleable iron to ASTM A-197. Black iron would be the choice for dry gas or dry-pipe work; this one is the corrosion-resistant version.
5) Do I need a bushing to reduce a 1-1/2 inch line down to a 1 inch branch?
Not with this one. The 1-1/2 x 1 x 1-1/2 tee reduces at the branch itself, so you thread 1-1/2 inch pipe into both run ends and 1 inch straight into the outlet. Skipping the bushing removes a joint and shortens the takeoff, which matters when you're tight to a wall or joist.
6) Is this an extra-heavy (150 lb vs 300 lb) fitting?
It's standard weight, not extra heavy. Standard malleable iron fittings are the common choice for plumbing, compressed air, and sprinkler branch piping; if your drawing calls out an extra-heavy Class 300 fitting, this is not the one. Pressure ratings follow ASME B16.3.
7) How much does this 1-1/2 x 1 x 1-1/2 malleable iron tee weigh?
1.54 lbs each. Worth knowing if you're ordering a pallet of them for a riser job or figuring hanger spacing on an overhead run of galvanized pipe.
