ASC Engineered Solutions 318900685 – Frequently Asked Questions
1) Will this 1-1/2 inch ASC malleable iron cap thread onto standard black steel pipe?
Yes. The ASC Engineered Solutions 1-1/2 inch black malleable iron cap has FPT (female pipe thread) ends cut to ASME B1.20.1, which is the standard NPT taper thread used on black and galvanized steel pipe. It screws onto the male threaded end of 1-1/2 inch pipe or a male fitting nipple. Use pipe dope or PTFE tape on the male threads to seal.
2) Is this ASC 1-1/2 inch black cap UL listed and FM approved for fire sprinkler piping?
It carries UL/FM approval, so it can be used to cap off a branch line or test connection on a fire protection system. It is a standard (STD) class malleable iron fitting made to ASTM A-197 with pressure ratings and dimensions per ASME B16.3. Confirm the pressure class matches your system design before installing.
3) Should I use a cap or a plug to close off a 1-1/2 inch pipe?
Depends which end you have. This ASC part is a cap with a female FPT thread, so it goes over a male pipe end or a nipple. If what you are closing is a female opening, such as a tee branch or a coupling, you need a plug with male threads instead. Both are made to the same ASME B1.20.1 thread standard, so the only question is the gender of the opening in front of you.
4) What is the difference between a black malleable iron cap and a galvanized one?
The finish decides where it belongs. This ASC cap is black malleable iron, the standard choice for dry service such as natural gas, fuel oil, compressed air, and closed-loop or dry fire protection lines. Galvanized fittings of the same ASME B16.3 dimensions are used where moisture or potable-adjacent wet service would rust a black fitting. Dimensionally they interchange, since both are cut to ASME B1.20.1 NPT threads.
5) What is the ASC part number and weight on the 1-1/2 inch black malleable iron cap?
Order it as ASC Engineered Solutions part 318900685. It weighs 0.73 lbs each, which matters if you are pricing freight on a case quantity or figuring hanger loads on a run with several capped stubs.
