ASC Engineered Solutions 310081807 – Frequently Asked Questions
1) What thread type does the ASC 4 inch black malleable iron coupling take on each end?
Both ends are 4 inch FPT, so it joins two male pipe ends. Threads are cut to ASME B1.20.1, the NPT standard, so it mates with standard NPT-threaded black steel or malleable iron pipe nipples in the same size.
2) Can a black malleable iron coupling be used on a water line, or is it gas and sprinkler only?
Black malleable iron is uncoated, so it is used on natural gas, air, and closed-loop or fire protection piping. For open potable water it will rust; a galvanized malleable iron coupling is the usual call there. This one is black finish, malleable iron to ASTM A-197.
3) Is this coupling a reducer or straight 4 inch?
Straight 4 by 4. Both openings are the same size, so it is a straight run splice, not a reducing coupling. For a step down you need a reducing coupling or a bushing.
