ASC Engineered Solutions 310538202 – Frequently Asked Questions
1) What size pipe does the ASC Engineered Solutions black malleable iron coupling take on each end?
Both ends are 3/8 inch female pipe thread (FPT), so it joins two runs of 3/8 inch threaded pipe. It is a straight coupling, not a reducer, since both ends are the same 0.375 size.
2) What does the XH marking mean on this 3/8 inch malleable iron coupling?
XH is extra heavy, a thicker-wall class than a standard Class 150 malleable fitting. Pressure ratings follow ASME B16.3, and the fitting is made to ASTM A-197 malleable iron. Contractors reach for XH when the line pressure or mechanical abuse on a small-diameter run is higher than a standard coupling is rated for.
3) Can I use a black malleable iron coupling on a potable water line?
No. Black malleable iron is for gas, fire protection, air, and similar non-potable service. The black finish is a plain uncoated iron, not galvanized, so it will rust in a wet water line. For water, use a galvanized malleable coupling or a copper/brass fitting instead.
4) What is the part number and weight for ordering the ASC 3/8 inch extra heavy black coupling?
Order by MPN 310538202. Each coupling weighs 0.26 lbs, which is the number to use when you are figuring hanger loads or a freight total on a case quantity.
