ASC Engineered Solutions 310507405 – Frequently Asked Questions
1) Will this 1/4 inch street elbow thread onto standard NPT pipe?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT taper thread spec, so it mates with any 1/4 inch NPT pipe, nipple, or port. Use thread sealant or PTFE tape as you would on any tapered iron thread joint.
2) Can I use a black malleable iron elbow on a potable water line?
No. Black malleable iron is for gas, air, steam, oil, and fire protection service, not potable water, because it corrodes and discolors the water. For potable water use galvanized or brass, or stay with copper or PEX.
3) Is this ASC 1/4 inch elbow acceptable for a fire sprinkler system?
It carries UL/FM recognition, so it can be specified on fire protection piping where the AHJ requires listed fittings. Confirm the system pressure against the XH class rating for the run you are installing it in.
4) What does XH mean on a black malleable iron fitting, and when do I need it instead of standard?
XH is extra heavy, meaning a thicker wall and a higher pressure rating than the standard class fitting of the same size. Reach for XH on higher pressure steam, compressed air, or hydraulic-type service where the standard 150 class fitting is marginal. For low pressure gas or general water runs, a standard fitting usually covers it.
5) What standard are the dimensions and pressure rating of this ASC malleable iron 90 built to?
Both the face-to-center dimensions and the pressure class follow ASME B16.3, and the castings are ASTM A-197 malleable iron. That means it drops into any layout dimensioned off B16.3 and will match other B16.3 fittings on the same run, regardless of who made them.
6) How much does the ASC 1/4 inch XH street elbow weigh for takeoff purposes?
0.17 lbs each. On a bulk order of small fittings that number is what you want for shipping weight and for load calcs on supported small-bore runs.
