ASC Engineered Solutions 310085402 – Frequently Asked Questions
1) Are both ends of the 1/2 x 3/8 black malleable iron reducer female threaded?
Both ends are FPT, so this is a female-to-female bell reducer. The large end takes 1/2 inch male pipe thread and the small end takes 3/8 inch. Threads are cut to ASME B1.20.1 (NPT), so it mates with standard threaded black or galvanized pipe nipples. If you need a male-to-female step, you want a bushing instead, not this reducing coupling.
2) Can I use a black malleable iron reducer on a gas line?
Black malleable iron fittings are the standard choice for gas and for non-potable, non-corrosive service. This one is made to ASTM A-197 malleable iron with a plain black finish and is dimensioned and pressure rated to ASME B16.3. The black finish is not a corrosion coating, so keep it out of wet or buried service and out of potable water lines. Always follow the gas code in force for your jurisdiction on fitting class and joint compound.
3) Is this reducer UL listed and FM approved for fire sprinkler work?
Yes, the ASC Engineered Solutions 1/2 x 3/8 black reducer carries UL/FM recognition, which is what an inspector looks for on fire protection piping. Note the sizes though: at 1/2 x 3/8 it is a small trim or gauge-line fitting, not a branch line fitting.
4) Is this a standard class or extra heavy malleable fitting?
Standard class. The strength rating is STD, which is the Class 150 malleable pattern under ASME B16.3. If your drawing calls for Class 300 extra heavy, this is not the fitting to use.
5) Will this black reducer hold up in an outdoor or damp mechanical room?
Plain black malleable iron with no protective plating will surface rust in damp or exposed conditions. For wet locations, condensate service, or anything buried, specify the galvanized version of the same 1/2 x 3/8 malleable reducer rather than the black finish.
6) What is the part number and weight on the ASC 1/2 x 3/8 black reducer for my purchase order?
Order it as ASC Engineered Solutions MPN 310085402. Each fitting weighs 0.17 lbs, which is worth knowing if you are pricing freight on a case quantity for an MRO stockroom.
