ASC Engineered Solutions 311009609 – Frequently Asked Questions
1) Is the ASC 1-1/2 x 1-1/4 galvanized malleable iron 90 elbow threaded on both ends, and what thread does it take?
Both openings are female pipe thread (FPT), cut to ASME B1.20.1, so it screws onto standard NPT male pipe ends or nipples. The larger opening takes 1-1/2 inch pipe and the smaller takes 1-1/4 inch, which makes it a reducing 90 that turns the run and steps the size down in one fitting. No adapters or bushings needed if your pipe is NPT.
2) Can I use this galvanized 90 elbow on a fire sprinkler line?
It carries UL/FM approval, so it is acceptable for fire protection piping where a UL Listed, FM Approved threaded malleable iron fitting is called for. It is a standard (STD) pressure class fitting rated per ASME B16.3. Confirm the class your sprinkler drawing specifies before installing.
3) Will a galvanized malleable iron elbow hold up on a wet or outdoor line?
The galvanizing is hot dip to ASTM A-153, which is the heavier coating spec used for corrosion service, over a malleable iron body made to ASTM A-197. That combination is what gets specified for water lines, exposed exterior piping, and sprinkler mains where black iron would rust. It is not intended for gas service lines that call for black fittings.
4) Does this reducing elbow match standard fitting takeout dimensions so my pipe cut lengths work out?
Yes. The fitting is made to ASME B16.3, the dimensional standard for threaded malleable iron fittings, so center-to-end and thread engagement match any other B16.3 1-1/2 x 1-1/4 reducing 90. You can cut pipe off standard takeout tables and it will land where the drawing says.
5) Do I need a reducing bushing with the ASC 311009609 elbow, or does it reduce on its own?
No bushing required. Model 311009609 is a reducing 90, with a 1-1/2 inch female threaded opening on one side and a 1-1/4 inch female threaded opening on the other, so the size change happens inside the fitting. Using a full-size 1-1/2 elbow plus a bushing adds a joint and a leak path you do not need here.
6) Is this elbow suitable for copper or PEX, or only for threaded steel pipe?
Threaded steel or iron pipe only. Both ends are female pipe thread per ASME B1.20.1, so the mating part has to be a male NPT end, a nipple, or a threaded adapter. Copper tube and PEX need their own transition fitting before you can land on this elbow.
7) How much does a 1-1/2 x 1-1/4 malleable iron 90 elbow weigh for hanger and support spacing?
It weighs 1.2 lbs. For a run of reducing 90s that adds up when you are sizing hangers or figuring shipping weight on a large fitting order.
