ASC Engineered Solutions 319900601 – Frequently Asked Questions
1) Will this 1 inch galvanized malleable iron cap thread onto standard 1 inch NPT pipe?
Yes. The cap is 1 inch with an FPT (female pipe thread) opening cut to ASME B1.20.1, which is the standard NPT thread spec, so it screws onto any 1 inch male NPT pipe end or male fitting nipple. Use pipe dope or PTFE tape on the male threads as you would with any tapered pipe thread joint.
2) Is this galvanized cap acceptable for a fire sprinkler line?
It carries UL/FM approval, and it is standard weight malleable iron with pressure rating and dimensions to ASME B16.3, which is the combination an AHJ looks for on threaded fire protection piping. Confirm the required pressure class for your system against the B16.3 standard-weight rating before you close out the riser.
3) Galvanized or black malleable cap, which one do I need?
Galvanized is the one to use on water lines, wet sprinkler systems, and anything exposed to weather or damp mechanical spaces, because the zinc coating (applied to ASTM A-153, hot dip) fights corrosion from the inside and out. Black malleable iron is for gas and dry service where the coating is not needed. Same malleable iron body and same ASME B16.3 dimensions either way, so a galvanized cap drops into the same prep as a black one.
4) What is the ASC Engineered Solutions 319900601 cap made of, and will it hold up on a galvanized steel water line?
Model 319900601 is malleable iron to ASTM A-197 with a galvanized finish to ASTM A-153. Pairing it with galvanized steel pipe keeps the system in matched material, which avoids the dissimilar-metal corrosion you get when you mix a brass or copper fitting straight into a galvanized run.
5) How much does one 1 inch galvanized malleable cap weigh for a shipment or takeoff?
0.38 lbs each. Handy if you are pricing freight on a large count for a multi-family or institutional job, or building a quantity takeoff where the fitting weight loads the hanger spacing calc.
