ASC Engineered Solutions 311088009 – Frequently Asked Questions
1) Does the ASC 1-1/4 x 1/2 galvanized malleable iron reducer have female threads on both ends?
Both ends are FPT, so the fitting threads onto male pipe ends. The large end takes 1-1/4 inch pipe, the small end takes 1/2 inch. Threads are NPT per ASME B1.20.1, which is what standard black or galvanized steel pipe is cut to.
2) Is this galvanized reducer approved for fire sprinkler piping?
It carries UL/FM approval, so it's acceptable on fire protection piping where a UL Listed, FM Approved fitting is called for. Standard (STD) class, galvanized malleable iron, which is the usual combination on wet and dry sprinkler branch lines.
3) Will this reducer meet a spec calling for ASME B16.3 malleable iron fittings?
Yes. Dimensions and pressure rating both follow ASME B16.3, the material is malleable iron to ASTM A-197, and the galvanized coating is to ASTM A-153 hot dip. Threads are ASME B1.20.1. That's the full stack most mechanical specs list for a Class 150 galvanized MI fitting.
4) Does STD mean standard weight, and is that heavy enough for my pressure?
STD is the standard weight class for this reducer, as opposed to an extra heavy fitting. Its pressure rating follows ASME B16.3, which sets the allowable working pressure by size and class for malleable iron threaded fittings. If your drawing calls for extra heavy or Class 300, this standard fitting is not the one.
5) Can I use a galvanized malleable iron reducer on a domestic potable water line?
Galvanized malleable iron reducers are traditional on water service and were the standard before copper and PEX took over, but potable water work today is governed by lead-free requirements that vary by jurisdiction. This fitting's published data covers dimensions, pressure, material and coating standards only. For air, gas, sprinkler, and general industrial service, the galvanized MI reducer is the normal choice.
6) What is the manufacturer part number for the ASC 1-1/4 x 1/2 galvanized MI reducer?
ASC Engineered Solutions part number 311088009. That's the number to quote when matching an existing submittal or reordering to the same spec.
7) How much does the 1-1/4 x 1/2 inch galvanized reducer weigh for shipping or a takeoff?
0.63 lbs each. Handy if you are weighing out a bulk order of fittings or figuring hanger loads on a branch run.
