ASC Engineered Solutions 310543202 – Frequently Asked Questions
1) What sizes does the ASC Engineered Solutions black malleable iron reducing coupling connect?
It reduces 1-1/4 inch down to 1 inch, with female pipe threads on both ends. Use it to step a 1-1/4 inch run down to 1 inch pipe or a 1 inch fitting without adding a bushing.
2) Are the threads on this 1-1/4 x 1 malleable iron reducer standard NPT?
Yes. The threads are cut to ASME B1.20.1, the US standard for tapered pipe threads, so they mate with any standard NPT male pipe end or nipple. Both ends are female.
3) What does XH mean on this black iron reducer, and how is it different from a standard one?
XH is extra heavy, a thicker wall and higher pressure class than the standard 150 class malleable fitting. Dimensions and pressure rating both follow ASME B16.3. If your drawing calls for standard weight, a 150 class reducer is the lighter, cheaper choice; specify XH only where the spec calls for extra heavy.
4) Can I use this reducer on a fire sprinkler line?
It is UL/FM listed, which is the approval fire protection contractors and AHJs look for on sprinkler piping. It is extra heavy black malleable iron with NPT female ends, which is the usual make-up for threaded wet system branch lines.
5) Is a black malleable iron reducer OK for a potable water line?
No. Black malleable iron is for gas, fire protection, and similar dry or non-potable service. The black finish has no corrosion protection against water, so for domestic water use galvanized, copper, or CPVC instead.
6) Should I use a reducing coupling or a bushing to go from 1-1/4 to 1 inch?
A reducing coupling like this one takes male threaded pipe on both sides, so it sits in the middle of a run. A bushing is male on the large side and female on the small side, and threads into an existing fitting port. If you are joining two pieces of pipe, the reducing coupling is the part; if you are stepping down a tee or valve outlet, you want a bushing.
7) What grade of iron is this reducer made from?
The casting is ASTM A-197 malleable iron, the standard material for threaded black iron fittings, finished plain black. Dimensional envelope is per ASME B16.3, so it interchanges with other B16.3 malleable fittings of the same size and class.
8) What is the manufacturer part number for this ASC reducer?
ASC Engineered Solutions part number 310543202, the 1-1/4 x 1 inch extra heavy black malleable iron reducer.
9) How much does the 1-1/4 x 1 extra heavy black reducer weigh?
1.27 lbs each. Worth knowing if you are pricing freight on a full box for a sprinkler or gas rough-in, since extra heavy fittings run noticeably heavier than standard class.
