ASC Engineered Solutions 310015805 – Frequently Asked Questions
1) Can I use a black malleable iron street elbow on a gas line?
Black malleable iron 90 street ells of this type are the standard fitting for black iron gas piping and for steam, air, and other non-corrosive service. The black finish is uncoated, not galvanized, so keep it off potable water lines, where galvanized or a non-ferrous fitting is the correct choice. The body is malleable iron to ASTM A-197 with dimensions and pressure ratings per ASME B16.3.
2) Is this ASC street elbow UL listed and FM approved for fire sprinkler work?
It carries UL/FM recognition, so it can go into fire protection piping where the AHJ requires listed fittings. Confirm the pressure class on your submittal matches, since this is the standard weight (STD) version.
3) When should I use a street elbow instead of a regular 90 elbow and a nipple?
Use the street ell when you need the turn tight to the component and have no room for a close nipple. A standard 90 has female threads both ends and needs a nipple to connect to another female port; the street version has the male thread built in, so it threads directly into a valve, gauge port, or tee. Same 1/4 inch NPT size on both ends here, so the run size does not change through the turn.
4) Do I still need thread sealant with this fitting?
Yes. NPT threads to ASME B1.20.1 are a tapered seal and rely on pipe dope or PTFE tape rated for the media, gas-rated sealant on fuel gas. The fitting itself ships with no sealant and none is needed on the female side beyond what you apply to the mating male thread.
