ASC Engineered Solutions 318900529 – Frequently Asked Questions
1) Is this malleable iron cap acceptable for a fire sprinkler system?
It carries UL/FM approval, so it can be used on fire protection piping where a listed fitting is required. It is standard (STD) pressure class malleable iron to ASME B16.3, black finish, so it suits dry black steel sprinkler mains and branch lines rather than wet potable water.
2) Can I use a black malleable iron cap on a domestic water line?
No. Black malleable iron is for gas, air, and fire protection piping, not potable water, because the uncoated iron rusts in wet service. For water you want a galvanized cap or a brass or bronze fitting. This one is the black finish version.
3) What standards does this ASC 1/2 inch malleable iron cap meet?
Three apply. Dimensions and pressure class follow ASME B16.3 for malleable iron threaded fittings, the iron itself is ASTM A-197, and the threads are ASME B1.20.1. It is also UL/FM approved. That combination is what most commercial and institutional specs call out for threaded black iron fittings.
4) How much does one 1/2 inch black malleable iron cap weigh for a materials takeoff?
0.12 lbs each. Handy if you are pricing out freight on a bulk order of caps for capping off risers or future branch stubs.
