ASC Engineered Solutions 311031603 – Frequently Asked Questions
1) Is the ASC Engineered Solutions 4 inch galvanized malleable iron tee threaded on all three openings?
All three openings are female pipe thread (FPT), and all three are 4 inch, so it's a straight tee with no reducing branch. Threads are cut to ASME B1.20.1, the NPT standard, so it mates with standard 4 inch threaded steel or iron pipe and with any other NPT fitting.
2) Can I use this 4 inch malleable iron tee on a fire sprinkler line?
It's UL/FM recognized, which is the approval fire protection inspectors look for on threaded fittings in sprinkler piping. It's a standard (STD) pressure class fitting rated per ASME B16.3, built from malleable iron to ASTM A-197. Confirm the class your sprinkler drawing calls for, since some risers spec 300 class fittings instead of standard.
3) What does the galvanized coating on this ASC malleable iron tee actually cover, and is it good for wet or outdoor lines?
The finish is hot dip galvanized to ASTM A-153, the spec for zinc coating on iron hardware. That gives it corrosion protection suitable for wet systems, exposed exterior runs, and damp mechanical rooms where black iron would rust at the threads. Pair it with galvanized pipe and galvanized nipples so you aren't mixing coatings at the joint.
4) Will this 4 inch tee match the dimensions on my piping drawing?
Center to end dimensions follow ASME B16.3, the dimensional standard for threaded malleable iron fittings, so it lays out the same as any other B16.3 4 inch standard class tee. If your drawing was laid out to B16.3 takeouts, this drops into the same space.
5) How heavy is a 4 inch galvanized malleable iron tee, and do I need to support it?
It weighs 11.53 lbs on its own, before any pipe. At 4 inch that's a two hand fitting, and with three full-size branches of water-filled pipe hanging off it you want hangers close to the tee rather than relying on the run. Plan rigging accordingly on overhead work.
6) Can I use a galvanized malleable iron tee on a gas line or a compressed air line?
The tee is a standard class threaded malleable iron fitting to ASME B16.3 with NPT threads, which is the same construction used across water, air, and gas service. What governs is your local code and the pressure class your job specifies, not the fitting family. Check the STD class rating in B16.3 against your system pressure before committing.
7) What is the ASC Engineered Solutions part number for the 4 inch galvanized tee?
Order it as model 311031603. That's the full-size 4 x 4 x 4 galvanized malleable iron tee with FPT ends. There's no size or finish variation to specify with it.
