ASC Engineered Solutions 310091400 – Frequently Asked Questions
1) What size pipe does the ASC 3 x 1-1/4 black malleable iron reducer connect?
It joins 3 inch pipe down to 1-1/4 inch pipe. Both ends are female pipe thread (FPT), so it threads directly onto male-threaded pipe ends or nipples of those two sizes. Threads follow ASME B1.20.1, the standard NPT thread spec, so it mates with any standard NPT black or galvanized pipe.
2) Is this reducer approved for fire sprinkler piping?
Yes, the 3 x 1-1/4 black malleable iron reducer carries UL/FM approval, which is what a sprinkler contractor or AHJ looks for on fire protection piping. It is a standard (STD) pressure class fitting built to ASME B16.3 for both dimensions and pressure rating.
3) Can I use a black malleable iron reducer on a potable water line?
No. Black malleable iron is for non-potable service: gas, air, steam, sprinkler and hydronic lines. The black finish is a mill coating with no corrosion protection for wet potable use, and there is no lead-free potable rating on this fitting. For domestic water, use a galvanized or copper/brass fitting instead.
4) What is the difference between a reducing coupling like this and a bushing?
This 3 x 1-1/4 part is a reducing coupling: both ends are female threaded, so it accepts male pipe on each side. A bushing has male thread on the large end and female on the small end, and screws into a fitting port rather than joining two pipes. If you are stepping down between two lengths of pipe, the female-by-female reducer is the piece you want; if you are reducing at a tee or valve outlet, you need a bushing.
5) Will this ASC reducer meet a spec calling out ASTM A197 malleable iron fittings?
Yes. The casting is made to ASTM A-197, with dimensions and pressure rating to ASME B16.3 and NPT threads to ASME B1.20.1. That is the standard three-spec callout on commercial and institutional piping drawings for Class 150 standard-weight malleable iron.
6) What is the ASC Engineered Solutions part number for this 3 x 1-1/4 black reducer?
The manufacturer part number is 310091400. That is the identifier to quote when matching an existing order or standardizing a stock of black malleable fittings across a facility.
