ASC Engineered Solutions 318901089 – Frequently Asked Questions
1) Will a 5 inch black malleable iron cap thread onto standard 5 inch black steel pipe?
Yes. The ASC Engineered Solutions 5 inch black malleable iron cap has a female pipe thread (FPT) end cut to ASME B1.20.1, which is the standard NPT thread used on schedule 40 black steel pipe. Thread it onto any male 5 inch NPT pipe end with pipe dope or PTFE tape.
2) Is this 5 inch malleable iron cap acceptable for a fire sprinkler system?
It carries UL/FM approval, so it can be used on fire protection piping where UL Listed and FM Approved fittings are specified. It is a black finish malleable iron cap, which is the usual material for wet-pipe sprinkler mains rather than galvanized dry systems.
3) What pressure class is the ASC 5 inch black malleable iron cap?
It is a standard (STD) class fitting, with pressure ratings per ASME B16.3, the same standard that governs its dimensions. Material is malleable iron to ASTM A-197. If your spec calls for an extra-heavy class 300 fitting, this standard-class cap is not the right part.
4) Can I use this black cap on a water supply or potable line?
No. Black malleable iron is for non-potable service, typically gas, fire protection, or compressed air and steam piping. For a potable water line you want a galvanized or brass fitting instead. The finish here is black, with no protective zinc coating.
5) Do I need anything else to cap off a 5 inch pipe with this fitting?
Just thread sealant. The cap is female threaded, so it screws directly onto a male pipe end with no coupling or nipple required. Use a pipe joint compound or PTFE tape rated for the service, and cut the pipe threads to ASME B1.20.1 so they match the cap.
6) How heavy is a 5 inch black malleable cap, and can one person install it overhead?
The cap weighs 6.45 lbs. That is a one-hand part on the bench, but at 5 inch you are turning it with a large pipe wrench, so overhead work on a live main is a two-person job in practice.
