ASC Engineered Solutions 311089403 – Frequently Asked Questions
1) Is the ASC 2 x 1 galvanized malleable iron reducer threaded on both ends, or does one end take male pipe?
Both ends are female pipe thread (FPT), so it takes male-threaded pipe or nipples on each side. Threads cut to ASME B1.20.1 NPT, so it mates with standard domestic threaded pipe. If you need a male-by-female step-down, you want a reducing bushing instead, not this coupling-style reducer.
2) What sizes does this ASC reducer step between?
It goes from 2 inch down to 1 inch, both female NPT. That is a two-size jump in one fitting, so you don't need to stack a 2 x 1-1/2 and a 1-1/2 x 1 to get there.
3) Can this galvanized malleable iron reducer be used on a fire sprinkler line?
It carries UL/FM approval, which is what an inspector looks for on sprinkler piping. It is standard weight (STD) malleable iron to ASTM A-197 with pressure rating per ASME B16.3. Confirm the pressure class on the drawing matches standard class before you commit it to the riser.
4) Is a galvanized malleable iron reducer OK for a wet or outdoor run, or should I use black iron?
Galvanized is the corrosion-resistant choice of the two. The coating here is hot dip to ASTM A-153, which is the spec for galvanizing on threaded hardware, so it suits wet lines, outdoor and damp mechanical rooms. Black malleable iron is the one to use on dry gas and steam service where the zinc is not wanted.
5) Will this reducer match the dimensions of the malleable fittings already on my system?
Yes, as long as those fittings are standard threaded malleable iron. This one is built to ASME B16.3, the dimensional standard for malleable iron threaded fittings, so the center-to-end and thread engagement match any other B16.3 fitting of the same size and class.
6) What is the part number and weight on the ASC 2 x 1 galvanized reducer?
Order it as MPN 311089403 from ASC Engineered Solutions. It weighs 1.4 lbs, which matters if you are pricing freight on a bulk pull or hanging a run with limited support spacing.
7) Do I need anything else to install this reducer?
The fitting ships as the reducer only. You supply thread sealant or PTFE tape, and male-threaded pipe or nipples on both sides since both openings are female NPT. No gaskets or mechanical couplings are involved.
