ASC Engineered Solutions 310008008 – Frequently Asked Questions
1) Is the ASC 3/4 x 3/8 black malleable iron 90 elbow a reducing fitting, and which end is which size?
It's a reducing 90, one end 3/4 inch and the other 3/8 inch, both female pipe thread. You use it where a 3/4 inch run turns and drops to a 3/8 inch branch, so you don't need a separate bushing at the turn. Both ends take male NPT pipe or nipples.
2) Can I use a black malleable iron 90 elbow on a domestic water line?
No. Black malleable iron fittings are for gas, air, steam, and other non-potable service. The black finish is a mill coating, not corrosion protection against water, and it will rust in a potable line. For water, use galvanized, brass, or copper. This ASC elbow is the black malleable iron version.
3) Is this ASC 90 elbow approved for fire sprinkler work?
It carries UL/FM approval, so it can be used on fire protection piping where the AHJ requires listed fittings. It's a standard weight malleable iron fitting made to ASME B16.3 for both dimensions and pressure rating.
4) Is this a Class 150 standard fitting or an extra-heavy 300?
Standard weight, which on malleable iron means Class 150 under ASME B16.3. If your drawing calls for Class 300 extra heavy, this is not the right fitting. The body is malleable iron produced to ASTM A-197.
5) Can I use this reducing elbow on a natural gas or propane line?
Black malleable iron threaded fittings are the usual choice for gas piping, and this one meets ASTM A-197 for material and ASME B16.3 for pressure and dimensions. Use an approved gas-rated thread sealant on the NPT joints and follow your local fuel gas code for sizing the 3/8 inch branch.
