ASC Engineered Solutions 310009402 – Frequently Asked Questions
1) Is the ASC 1-1/4 x 1/2 black malleable iron 90 elbow a reducing fitting, and which end is which size?
It's a reducing 90 degree elbow: one end is 1-1/4 inch, the other is 1/2 inch. Both ends are female pipe thread (FPT), so it threads onto male-threaded pipe nipples or male-end fittings on both sides. Use it where a 1-1/4 inch run has to turn and drop to a 1/2 inch branch without adding a separate bushing.
2) Can I use a black malleable iron elbow on a potable water line?
No. Black malleable iron is for gas, air, and non-potable service such as black iron gas piping, compressed air, and fire sprinkler work. It has no protective coating and will rust in potable water. For water lines use galvanized, copper, or PEX fittings instead.
3) Is this ASC reducing elbow approved for fire sprinkler piping?
It carries UL/FM approval, so it can be used on fire protection piping where UL Listed and FM Approved fittings are specified. It's a standard (STD) pattern malleable iron fitting rated per ASME B16.3.
4) What specs does this malleable iron 90 elbow meet for a submittal?
Three specs cover it: material to ASTM A-197 malleable iron, dimensions and pressure class to ASME B16.3 (Class 150 standard pattern), and threads to ASME B1.20.1. It's also UL/FM approved. That set is what most mechanical and fire protection submittals ask for on a black iron fitting.
5) Do I still need a reducing bushing with this 1-1/4 x 1/2 elbow?
No. The reduction is built into the fitting, so a 1-1/4 inch pipe goes into one side and a 1/2 inch nipple or pipe into the other with no bushing between them. That saves you a joint and keeps the takeoff tight to the turn, which matters when you're working in a joist bay or against a wall.
6) Is a standard pattern malleable iron elbow strong enough, or should I use extra heavy?
This one is standard (STD) pattern, rated per ASME B16.3, which is Class 150 and covers the large majority of black iron gas, air, and sprinkler work. Step up to an extra heavy (Class 300) malleable fitting only when the design pressure or a spec on the drawing calls for it.
7) What is the part number and weight on the ASC 1-1/4 x 1/2 black 90 elbow?
The manufacturer part number is 310009402 and each fitting weighs 0.61 lbs. That weight is useful if you're figuring hanger spacing or freight on a bulk order of black iron fittings.
