ASC Engineered Solutions 310089206 – Frequently Asked Questions
1) Is the ASC 2 x 1-1/4 black malleable iron reducer female threaded on both ends?
Both ends are female pipe thread (FPT), so it threads onto male pipe ends or male adapters on each side. It steps 2 inch pipe down to 1-1/4 inch. Threads are cut to ASME B1.20.1 (NPT), which is what standard black, galvanized, and brass threaded pipe is cut to, so it mates with any NPT male thread in those sizes.
2) Is a black malleable iron reducer OK for potable water?
No. Black malleable iron is uncoated and will rust in potable water service; it is used on natural gas, air, and fire protection or closed loop hydronic piping. For domestic water you want the galvanized version of the same 2 x 1-1/4 reducer, or a brass or stainless reducing coupling in those sizes.
3) Will a 2 x 1-1/4 ASME B16.3 reducer match the fittings already on my existing black iron gas line?
Yes, as long as the existing run is threaded black iron. Dimensions follow ASME B16.3, the standard-class malleable iron threaded fitting dimensional standard, so face-to-face and thread engagement match any other B16.3 standard-class reducer in the same 2 x 1-1/4 size regardless of who made it. That means it drops into an existing layout without re-cutting pipe lengths.
4) What is the difference between this reducer and a bushing for going from 2 inch to 1-1/4 inch?
This one is a reducing coupling: female threads on both ends, so it sits between two male pipe ends and adds a short run of length. A hex bushing is male on the large side and female on the small side, and it threads into a female port like a valve or a tee, taking up almost no space. Use the reducing coupling when both sides are threaded pipe; use the bushing when the large side is a female fitting.
5) How heavy is the 2 x 1-1/4 malleable iron reducer, and do I need thread sealant with it?
It weighs 1.53 lbs, light enough to hang on a supported run without extra bracing. Threads are NPT tapered per ASME B1.20.1, so they need pipe dope or PTFE tape rated for the service, gas rated sealant on fuel gas lines. The fitting ships bare with no sealant included.
6) What is the exact part number for the ASC 2 x 1-1/4 black reducer?
Order it as ASC Engineered Solutions MPN 310089206. That covers the 2 inch by 1-1/4 inch black malleable iron reducing coupling in standard pressure class.
