ASC Engineered Solutions 310539002 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions black malleable iron coupling take?
It's a 1-1/4 inch coupling, same size on both ends (1.25 by 1.25), with female pipe thread on each side. So it joins two runs of 1-1/4 inch threaded pipe straight through, no size change.
2) What does XH mean on a malleable iron coupling, and when do I need it instead of a standard one?
XH is extra heavy, meaning a thicker wall and a higher pressure rating than a standard (Class 150) malleable fitting of the same size. Use XH where the system pressure or the mechanical loading on the joint exceeds what a standard-class fitting is rated for. Pressure ratings and dimensions here follow ASME B16.3.
3) Is a black malleable iron coupling OK for potable water?
No. Black malleable iron is for gas, fire protection, steam, compressed air and other non-potable service. On a domestic water line you want galvanized, copper, CPVC or PEX instead, because black iron will rust in wet potable service.
4) Is this a straight coupling or a reducing coupling?
Straight. Both ends are 1-1/4 inch female threads, so there is no size change across the fitting. If you need to step down from 1-1/4 inch, you want a reducing coupling or a bushing instead.
5) What part number do I order for the 1-1/4 inch extra heavy black coupling?
ASC Engineered Solutions part number 310539002. Shipping weight on the fitting is 1.63 lbs.
