ASC Engineered Solutions 311044408 – Frequently Asked Questions
1) What size openings does the ASC Engineered Solutions 311044408 galvanized malleable iron tee have?
It is a reducing tee with a 1-1/4 inch run and two 3/4 inch openings. All three ports are female pipe thread (FPT), so it takes male-threaded pipe nipples on every side. Use it where a 1-1/4 inch line needs to branch or step down to 3/4 inch.
2) Will this galvanized tee thread onto standard NPT pipe?
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 galvanized pipe nipple of the matching size. Dimensions follow ASME B16.3 for malleable iron threaded fittings, so it drops into a layout built around standard fitting take-outs.
3) Is this tee UL listed and FM approved for fire sprinkler work?
Yes, the 1-1/4 x 3/4 x 3/4 galvanized malleable iron tee carries UL/FM recognition, which is what an inspector looks for on threaded branch lines in a sprinkler system. It is a standard (STD) pressure class fitting per ASME B16.3.
4) Is the galvanizing on this malleable iron tee good enough for outdoor or damp locations?
The coating is hot-dip galvanizing to ASTM A-153, the specification for zinc coating on iron hardware. That is the finish used for wet, outdoor, and corrosion-prone service and it is why these fittings go into wet sprinkler systems and exposed piping rather than black iron.
5) Should I use a malleable iron threaded tee or a cast iron one on a threaded water line?
Malleable iron, made to ASTM A-197, is the one for threaded pressure piping. It is ductile enough to take thread cutting and the stress of being wrenched tight, where gray cast iron drainage fittings are brittle and are meant for gravity DWV, not pressurized threaded joints. This tee is malleable iron in the standard pressure class.
6) Do I need a bushing to run 3/4 inch branch off a 1-1/4 inch line with this fitting?
No bushing needed. This is a reducing tee: the 1-1/4 inch run and both 3/4 inch outlets are built into the one casting, so you thread 1-1/4 inch pipe into the run and 3/4 inch nipples into the branches. Using a full-size tee plus bushings adds two more leak paths and more take-out length.
