ASC Engineered Solutions 318907680 – Frequently Asked Questions
1) Can I use a 2 x 1-1/2 black malleable iron hex bushing to reduce a 2 inch pipe fitting down to 1-1/2 inch pipe?
That is exactly what it does. The bushing has a 2 inch male pipe thread (MPT) on the outside and a 1-1/2 inch female pipe thread (FPT) inside, so it threads into a 2 inch female port and gives you a 1-1/2 inch female connection. Threads are NPT per ASME B1.20.1, so it mates with standard tapered pipe thread. Use pipe dope or PTFE tape on the tapered threads.
2) Is a black malleable iron hex bushing OK for a wet fire sprinkler line?
It is UL/FM recognized, and it is built to the standard-weight malleable iron fitting specs sprinkler work is usually written around: ASTM A-197 malleable iron, dimensions and pressure rating per ASME B16.3, NPT threads per ASME B1.20.1. Black finish is the normal choice for wet pipe sprinkler and closed-loop systems. Confirm the size reduction is permitted at that point by your approved layout.
3) Should I use black or galvanized malleable iron for a reducing bushing on a domestic water line?
Use galvanized, not this one. The ASC 2 x 1-1/2 hex bushing is black malleable iron, which is intended for gas, steam, air, and closed-loop hydronic or fire protection service. Black iron corrodes in potable water. For potable domestic water, specify a galvanized malleable iron bushing in the same 2 x 1-1/2 size, or a brass or bronze bushing.
4) Is this ASC hex bushing standard weight or extra heavy?
Standard weight (STD), with the pressure rating taken from ASME B16.3. If your drawing calls for a 300 lb extra-heavy Class 300 malleable iron fitting, this standard-pattern bushing is not the substitute. It weighs 0.64 lbs.
5) Will a 2 x 1-1/2 hex bushing fit the threaded outlet on my black iron gas pipe tee?
If that outlet is a 2 inch female NPT, yes. The bushing's large end is 2 inch MPT cut to ASME B1.20.1, the same thread standard used on schedule 40 black iron pipe and standard malleable fittings, and the fitting dimensions follow ASME B16.3. Thread it into the 2 inch outlet and you are left with a 1-1/2 inch female NPT. Check local code on whether a bushing is allowed at that location on fuel gas piping.
6) What part number do I order for the ASC Engineered Solutions 2 x 1-1/2 black hex bushing?
Order ASC Engineered Solutions MPN 318907680. It is one configuration, 2 inch MPT by 1-1/2 inch FPT, black malleable iron, standard weight, so there are no finish or size options to specify.
