ASC Engineered Solutions 311081400 – Frequently Asked Questions
1) What thread does the ASC 2-1/2 inch galvanized malleable iron coupling take, and will it mate with standard steel pipe?
Both ends are 2-1/2 inch FPT (female pipe thread) cut to ASME B1.20.1, the NPT thread standard. That means it threads directly onto any 2-1/2 inch male NPT pipe nipple or threaded steel pipe end. Use pipe dope or PTFE tape as your system requires.
2) Is this a reducing coupling or straight 2-1/2 inch on both ends?
Straight. Both ends are 2-1/2 inch, so it joins two pipes of the same size. If you need to step down from 2-1/2 inch to a smaller line, you want a reducing coupling or a bushing instead.
3) Can this galvanized malleable iron coupling be used on a fire sprinkler line?
It carries a UL/FM listing, so it is acceptable for fire protection piping where a listed threaded fitting is required. It is a standard (STD) pattern malleable iron fitting rated to ASME B16.3.
4) Is the galvanizing on this ASC coupling hot-dip, and is it OK outdoors or buried?
The zinc coating is applied to ASTM A-153, which is the hot-dip galvanizing standard for iron and steel hardware. That coating is what makes the fitting suitable for wet, humid, and exterior service rather than bare black iron.
5) What is this ASC coupling made of and what standard is the casting to?
Malleable iron cast to ASTM A-197, with dimensions to ASME B16.3. Malleable iron is used here rather than cast iron because it tolerates the stress of threading and wrench-tightening without cracking.
