ASC Engineered Solutions 310007604 – Frequently Asked Questions
1) Is this elbow UL Listed and FM Approved for fire sprinkler work?
Yes. The fitting carries UL/FM recognition, so it can be used on fire protection piping where the AHJ requires listed fittings. It's a standard pattern (STD) malleable iron fitting built to ASME B16.3 for both dimensions and pressure rating.
2) Will a black malleable iron 90 work on a gas line in my building?
Black malleable iron threaded fittings to ASME B16.3 with NPT threads are the usual choice for natural gas and propane piping, and that's what this is. Both ends are female, so you thread it onto black steel nipples, and joints get a gas-rated thread sealant. Confirm your local code accepts threaded black iron for the pressure and location involved before piping it in.
3) What grade of malleable iron is this fitting made from?
The casting is made to ASTM A-197, the standard for cupola malleable iron used in threaded pipe fittings. Pressure class is standard (150) pattern per ASME B16.3, which is the common weight for gas and low-pressure air piping. If your spec calls for extra-heavy 300 class, this one won't satisfy it.
4) Do I need a bushing to go from 1/2 inch down to 1/4 inch pipe?
Not with this fitting. A reducing 90 handles the turn and the size change together, which saves you a nipple and a reducing bushing and keeps the assembly shorter, useful when you're dropping off a 1/2 inch header to a 1/4 inch gauge, pilot line, or instrument tap. If you need the reduction on a straight run instead of a corner, a reducing coupling or hex bushing is the right part.
5) What is the ASC part number and weight for the 1/2 x 1/4 black 90 ell?
Order it as ASC Engineered Solutions MPN 310007604. Each fitting weighs 0.19 lbs, so a case of them adds very little to a service truck or a shipment of pipe.
