ASC Engineered Solutions 310089404 – Frequently Asked Questions
1) Does the ASC 2 x 1 black malleable iron reducer have female threads on both ends?
Both ends are FPT, so this is a female-by-female bushing-style reducer: 2 inch FPT on the large end and 1 inch FPT on the small end. You thread male pipe nipples into each side. If you need a male end to thread into a fitting, a reducing bushing is the part to look for instead.
2) Will this reducer thread onto standard NPT pipe?
Yes. Threads are cut to ASME B1.20.1, which is the standard NPT taper thread spec, so it mates with ordinary black steel pipe and nipples of the same size. Use pipe dope or PTFE tape on the taper as you would with any NPT joint.
3) Is this ASC reducer UL listed and FM approved for a fire sprinkler line?
It carries UL/FM recognition, which is what an inspector looks for on fire protection piping. It's a standard-pattern black malleable iron fitting built to ASME B16.3, the usual choice for wet sprinkler mains and branch lines.
4) Can I use a black malleable iron reducer on a potable water line?
No. Black malleable iron is for gas, fire protection, steam, and non-potable service. The black finish here has no galvanizing or lining, so it will rust in a water supply line. For potable water, use a galvanized or copper/brass fitting instead.
5) What material spec does this malleable iron reducer meet?
Castings are ASTM A-197, the standard for cupola malleable iron used in threaded pipe fittings. Paired with the ASME B16.3 dimensional and pressure spec, that's what a submittal package for mechanical or fire protection work typically asks for.
6) Can I use this to step 2 inch pipe down to 1 inch in one fitting?
Yes, it makes the full two-size drop in a single fitting: 2 inch FPT to 1 inch FPT. No intermediate bushings or a 2x1-1/2 plus 1-1/2x1 stack needed, which keeps the run shorter and cuts two potential leak points.
7) What is the ASC part number and weight for the 2 x 1 black reducer?
Order as ASC Engineered Solutions MPN 310089404. It weighs 1.4 lbs each, worth knowing if you're pricing freight on a full box of them for a riser job.
