ASC Engineered Solutions 311039804 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 311039804 galvanized malleable iron tee?
It's a reducing tee: two 1 inch runs and a 3/4 inch branch. All three openings are female pipe thread (FPT), so it takes male threaded pipe nipples on every port. Use it where you're running 1 inch line and dropping to 3/4 inch for a branch takeoff.
2) Is this tee approved for fire sprinkler piping?
It carries UL/FM approval, so it can be used in fire protection piping where UL Listed and FM Approved malleable iron fittings are called for. It's a standard weight (STD) fitting dimensioned and pressure rated to ASME B16.3.
3) Can I use a galvanized malleable iron tee on a steel pipe water line?
Galvanized malleable iron fittings are the normal match for galvanized steel pipe in water service. The body is malleable iron to ASTM A-197 with a hot dip galvanized coating to ASTM A-153, which is the same coating spec used on galvanized pipe, so you're not mixing dissimilar finishes at the joint. Don't run it on copper without a dielectric union.
4) Is this the standard weight tee or extra heavy (150 vs 300 class)?
Standard weight. The strength rating is STD, which is the 150 class malleable iron fitting, rated per ASME B16.3. If your spec calls for extra heavy / 300 class, this isn't the fitting.
5) Which port is the 3/4 inch on this reducing tee?
The 3/4 inch is the branch outlet; the two 1 inch ends form the straight run. Read the callout in order: 1 x 1 x 3/4 means run, run, branch. If you need the reduction on the run instead, you want a different size combination.
6) How much does the 1 x 1 x 3/4 galvanized tee weigh for a takeoff or freight estimate?
0.84 lbs each. Handy if you're pricing out a bulk count for a riser or a sprinkler branch run.
