ASC Engineered Solutions 310095427 – Frequently Asked Questions
1) What thread ends does the ASC 3/4 inch black malleable iron extension piece have?
One end is female pipe thread (FPT) and the other is male pipe thread (MPT), both 3/4 inch. So it threads onto a 3/4 inch male nipple or fitting on the female side, and screws into a 3/4 inch female port on the male side. Threads are cut to ASME B1.20.1, the standard NPT tapered pipe thread spec, so it mates with any other NPT 3/4 inch iron pipe fitting.
2) Can I use a black malleable iron extension piece on a wet sprinkler line?
It's UL/FM rated, which is what a fire protection inspector looks for on fire sprinkler piping components. The black malleable iron body is built to ASTM A-197 with dimensions and pressure rating per ASME B16.3 at standard (STD) class. Black iron is the normal choice for dry gas and closed fire protection piping, not for potable water.
3) Is this 3/4 inch fitting rated for gas piping?
Black malleable iron with NPT threads is the standard material for black iron gas piping, and this one is made to ASTM A-197 with ASME B16.3 pressure ratings in standard class. Local gas code governs what's permitted in your jurisdiction, so check the authority having jurisdiction for the application.
4) What is the ASC part number and weight for the 3/4 inch black extension piece?
Order it as ASC Engineered Solutions part 310095427 (also called the 1138 pattern). It weighs 0.32 lbs each, which matters if you're pricing out freight on a bulk fitting order.
