ASC Engineered Solutions 311045207 – Frequently Asked Questions
1) Which outlet on the 3/4 x 3/4 x 1-1/4 galvanized malleable iron tee is the larger one?
It's a bull head tee: the two run ends are 3/4 inch and the branch outlet is 1-1/4 inch, so the side outlet is larger than the run. All three openings are female pipe thread (FPT), so pipe or nipples thread into the fitting at every port.
2) Can I use this galvanized tee on a fire sprinkler line?
It carries a UL/FM listing, which is what an AHJ looks for on fire protection piping. It's malleable iron to ASTM A-197 with standard pressure class per ASME B16.3. Confirm the pressure class matches your system design before installing.
3) Is this a Class 150 standard fitting or extra heavy?
Standard strength, rated and dimensioned to ASME B16.3. Extra heavy (Class 300) malleable fittings are a different part with thicker walls and a different face-to-center dimension, so don't substitute this one where the drawing calls for 300.
4) Will a galvanized malleable iron tee work for potable water or is it only for gas and sprinkler?
The hot dip galvanized coating is applied to ASTM A-153, which is the zinc coating standard used on threaded iron fittings for corrosion resistance in wet service. Galvanized malleable iron is commonly run on water lines; black malleable is the one used for fuel gas. For potable systems, check your local code on the use of galvanized steel piping.
5) Do the dimensions of this tee match other brands' malleable iron fittings?
They do. The tee is built to ASME B16.3 dimensions, so center-to-face lengths match any other B16.3 standard class malleable fitting in the same sizes. That means it drops into an existing run without re-cutting nipples when you're replacing a like-for-like 3/4 x 3/4 x 1-1/4 tee.
6) What does the 3/4 x 3/4 x 1-1/4 tee weigh for a takeoff?
0.93 lbs each. Useful when you're figuring hanger spacing or freight on a bulk fitting order.
7) What's the ASC part number for this galvanized reducing tee?
Order it as ASC Engineered Solutions model 311045207, a galvanized malleable iron tee, 3/4 x 3/4 x 1-1/4, all female threaded.
