ASC Engineered Solutions 318901345 – Frequently Asked Questions
1) Will this 1 inch black malleable iron cap thread onto standard 1 inch NPT pipe?
Yes. The ASC Engineered Solutions 1 inch extra heavy black cap has an FPT (female pipe thread) end cut to ASME B1.20.1, which is standard NPT tapered pipe thread. It screws onto the male threaded end of 1 inch pipe or onto a male nipple. Use pipe dope or PTFE tape as your spec requires; tapered threads seal on the thread engagement, not on a gasket.
2) Can I use a black malleable iron cap on a potable water line?
No. Black malleable iron is for non-potable service: black steel pipe systems such as fire sprinkler, natural gas, compressed air, and closed-loop hydronic heating. The black finish is a mill coating, not a corrosion barrier for wet potable service. For domestic water you want galvanized, brass, or copper, depending on the spec.
3) Will an extra heavy malleable cap fit the same as a standard weight one on my 1 inch pipe?
Yes on the thread, since both are made to ASME B16.3 dimensions with ASME B1.20.1 NPT threads, so an XH 1 inch cap goes onto the same 1 inch male pipe end as a standard cap. The difference is outside: the extra heavy cap has a heavier body, so check clearance if you are capping in a tight chase or against adjacent piping.
