ASC Engineered Solutions 311080600 – Frequently Asked Questions
1) Will a 1 inch galvanized malleable iron coupling thread onto standard 1 inch threaded pipe?
Yes. Both ends of the ASC Engineered Solutions 1 inch galvanized coupling are 1 inch FPT (female pipe thread), cut to ASME B1.20.1, which is the standard NPT thread used on schedule 40 threaded steel and galvanized pipe. It joins two male-threaded 1 inch pipe ends or nipples in a straight run.
2) Is this 1 inch malleable iron coupling UL listed and FM approved for a fire sprinkler line?
It carries UL/FM recognition, so it can be used on threaded fire protection piping where a UL Listed, FM Approved fitting is called for. It is a standard (STD) pattern galvanized malleable iron coupling with pressure rating per ASME B16.3.
3) Can I use a galvanized malleable iron coupling on a wet or outdoor line?
The galvanized finish is hot dip applied to ASTM A-153, which is the coating spec for galvanizing on hardware and fittings, so the fitting is suited to wet service, damp environments, and outdoor exposed runs where black iron would rust. Body material is malleable iron to ASTM A-197.
4) Is this a standard or extra heavy 1 inch coupling?
Standard pattern. The strength class is STD, dimensioned and pressure rated to ASME B16.3, which is the Class 150 malleable iron threaded fittings standard. If your drawing calls for Class 300 extra heavy, this is not the fitting for that line.
5) Will this coupling work on copper, PVC, or grooved pipe?
No. This is a threaded fitting only, with 1 inch female NPT on both ends per ASME B1.20.1. It will not solder to copper, solvent weld to PVC, or accept a grooved end. For those systems you need a fitting made for that joining method, or a threaded adapter to transition into this coupling.
6) Does a threaded coupling like this need pipe dope or PTFE tape?
Yes. NPT threads to ASME B1.20.1 are a tapered thread that seals on thread engagement, so a thread sealant or PTFE tape on the male pipe ends is standard practice. Nothing is supplied with the coupling itself.
