ASC Engineered Solutions 310080205 – Frequently Asked Questions
1) What thread does the 1/2 inch black malleable iron coupling take on each end?
Both ends are 1/2 inch FPT, female tapered pipe thread cut to ASME B1.20.1 (NPT). It joins two lengths of 1/2 inch threaded black steel or black iron pipe, male thread into female. Use pipe dope or PTFE tape on the male threads as you would on any tapered joint.
2) Is this a reducing coupling or straight 1/2 inch both ends?
Straight. Size 1 and Size 2 are both 1/2 inch, so it is a same size coupling. If you need to step from 1/2 inch to 3/8 or 3/4, you want a reducing coupling or a bushing instead.
3) Can I use a black malleable iron coupling on a fire sprinkler line?
This ASC Engineered Solutions coupling is UL/FM rated, so it is acceptable for fire protection piping where a UL Listed and FM Approved fitting is called for. It is a Class 150 standard pattern fitting per ASME B16.3, black finish, which is the usual choice for dry sprinkler and standpipe branch work.
4) Can I use a black 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 carries no corrosion protection for wet potable service, and potable lines need a lead free certified fitting. For water distribution use galvanized, copper, brass, or CPVC as the job specifies.
5) Is this coupling standard or extra heavy pattern?
Standard (STD) pattern, dimensioned and pressure rated to ASME B16.3, which is the Class 150 malleable iron standard. If your drawing calls for Class 300 extra heavy malleable iron, this is not the fitting; you need a 300 pattern coupling.
6) What is the part number and weight for ordering this 1/2 inch black coupling in bulk?
ASC Engineered Solutions part number 310080205, 0.2 lbs each. Useful if you are stocking a truck or building a shipping estimate on a full case.
