ASC Engineered Solutions 319900528 – Frequently Asked Questions
1) Will the ASC 1/2 inch galvanized malleable iron cap thread onto 1/2 inch black or galvanized steel pipe?
Yes. The cap is 1/2 inch with a female pipe thread (FPT) end, cut to ASME B1.20.1 NPT threads, so it screws onto any standard 1/2 inch threaded steel or iron pipe nipple. The galvanized coating makes it the natural match for galvanized pipe, but the thread engagement is identical on black pipe.
2) Is this 1/2 inch malleable iron cap acceptable for capping a fire sprinkler line?
It carries UL/FM approval, which is what an AHJ looks for on fire protection piping. The fitting is Class 150 standard pattern malleable iron to ASME B16.3 with NPT threads, the usual arrangement for capping a branch line or an unused outlet in a wet system.
3) Is the galvanizing on this cap hot dip, and will it hold up outdoors?
The coating is specified to ASTM A-153, the hot dip galvanizing standard for hardware and fittings, over a malleable iron body made to ASTM A-197. That zinc layer is what lets it be used on exposed exterior or damp mechanical room piping rather than only in dry interior runs.
4) Can I use a galvanized malleable iron cap on a potable water line?
Nothing in the specification for this fitting addresses potable water contact. It is a galvanized malleable iron cap built to ASME B16.3 with NPT threads, commonly run on fire protection, compressed air, gas and general mechanical piping. If the job requires a potable-rated fitting, specify brass or a stainless cap instead.
