ASC Engineered Solutions 319900643 – Frequently Asked Questions
1) Will this 1-1/4 inch galvanized cap thread onto standard 1-1/4 inch steel pipe?
Yes. The ASC Engineered Solutions malleable iron cap is a 1-1/4 inch female pipe thread (FPT) fitting cut to ASME B1.20.1, the standard NPT thread spec, so it threads directly onto the male end of 1-1/4 inch galvanized or black steel pipe. No adapter needed as long as the pipe end is threaded NPT.
2) Is this malleable iron cap approved for fire sprinkler piping?
It carries UL/FM recognition, which is what an inspector looks for on fire protection piping. The cap is standard weight (STD) malleable iron, galvanized, dimensioned and pressure rated to ASME B16.3 with ASME B1.20.1 threads, which is the usual class of fitting used to cap off a sprinkler branch line or a future outlet.
3) Can I use a galvanized malleable iron cap on a domestic water line?
Galvanized malleable iron caps are used on galvanized steel water and general service piping, and this one is hot dip galvanized to ASTM A-153 for corrosion protection. Match the fitting finish to the pipe: put galvanized fittings on galvanized pipe and black fittings on black pipe, otherwise you set up a dissimilar metal joint that corrodes at the thread.
4) Does this cap meet standard pipe fitting dimensions so it will fit a spec that calls out ASME B16.3?
It is dimensioned and pressure rated to ASME B16.3, the standard for threaded malleable iron fittings, with material to ASTM A-197 and threads to ASME B1.20.1. That is the exact stack a mechanical spec normally calls for on Class 150 standard weight malleable iron, so it submits cleanly against a B16.3 callout.
5) Do I need pipe dope or PTFE tape on this threaded cap?
Yes, tapered NPT threads seal on the thread engagement plus a sealant. The cap is cut to ASME B1.20.1 tapered pipe thread, so use pipe joint compound or PTFE tape rated for the service, and note that for UL/FM fire protection work the sealant also has to be acceptable for that system.
