ASC Engineered Solutions 310009600 – Frequently Asked Questions
1) Will this black iron elbow thread onto standard NPT pipe?
It will. The threads are cut to ASME B1.20.1, which is the standard NPT pipe thread spec, so it mates with ordinary threaded black steel pipe nipples and cut-and-threaded pipe. Both ends are female, so you thread male pipe ends into it.
2) Can I use this malleable iron elbow on a fire sprinkler line?
It carries a UL/FM listing, which is what an AHJ looks for on fire protection piping. It's a standard-weight (STD) malleable iron fitting rated to ASME B16.3. Confirm the listed pressure class matches your system design pressure on the approval submittal.
3) Will this reducing elbow interchange with another brand's 1-1/2 x 1-1/4 black 90?
It's built to ASME B16.3, the dimensional standard for threaded malleable iron fittings, so center-to-end lay length and thread engagement match any other B16.3 standard-class 1-1/2 x 1-1/4 black 90. You can swap it into an existing run without re-cutting pipe.
4) Is a black malleable iron elbow OK for gas piping, or do I need galvanized?
Black malleable iron is the usual choice for natural gas and propane black-iron systems, and galvanized is generally avoided on gas because the zinc can flake. This fitting is black finish malleable iron built to ASTM A-197 with B1.20.1 threads. It's not intended for potable water, where you'd use copper, PEX, or brass.
5) Do I need pipe dope or tape with this fitting, or does it seal on its own?
The elbow ships as a bare threaded fitting with no sealant applied. NPT threads seal on interference at the taper, but you still need a thread sealant rated for the service, gas-rated dope or PTFE tape for fuel gas. No gaskets or hardware are included.
6) Which end of this elbow is the 1-1/2 and which is the 1-1/4?
By the standard fitting convention the first size listed is the run end, so the 1-1/2 inch tap takes the larger line and the 1-1/4 inch tap the smaller branch. Both are female threads, so orientation on the job is just a matter of which nipple goes where.
7) What is the model number to order this ASC reducing elbow?
Order it by MPN 310009600 from ASC Engineered Solutions, described as 1-1/2 x 1-1/4 black malleable iron 90 ell. One configuration only, so there are no finish or size options to select.
