ASC Engineered Solutions 311038806 – Frequently Asked Questions
1) What are the three port sizes on the ASC 3/4 x 1/2 x 1/2 galvanized malleable iron tee?
It is a reducing tee: the run is 3/4 inch on one end and 1/2 inch on the other, with a 1/2 inch branch outlet. All three openings are female pipe thread (FPT), so it takes male-threaded pipe nipples on every port.
2) Is this tee suitable for a wet sprinkler line?
It carries a UL/FM listing, which is the approval fire protection contractors and inspectors look for on fitting used in sprinkler piping. It is standard weight malleable iron, galvanized, threaded to NPT, and dimensioned per ASME B16.3.
3) Can I use this reducing tee to drop a 1/2 inch branch off a 3/4 inch line?
That is exactly what it is for, but watch the run. The run reduces from 3/4 to 1/2, so it is not a straight 3/4 run with a 1/2 branch. If you need to keep 3/4 through the run, you want a 3/4 x 3/4 x 1/2 tee instead.
4) Is this a Class 150 standard fitting or an extra-heavy 300 pattern?
Standard weight (STD), with pressure rating and dimensions to ASME B16.3. That is the common threaded malleable iron pattern for water, air, gas and sprinkler service. If your drawing calls out extra heavy, this is not that fitting.
5) What is the galvanized coating on this malleable iron tee, and will it hold up outdoors?
The zinc coating is applied to ASTM A-153, the hot-dip galvanizing spec for hardware and fittings. That is the coating normally specified for damp, outdoor, and corrosive-exposure runs rather than plain black iron. Body casting is malleable iron to ASTM A-197.
6) Can I mix this galvanized fitting with black iron pipe on a gas line?
Threads match either way, since both use NPT to ASME B1.20.1, so it will physically make up on black pipe. Most gas and fire codes and job specs require one material throughout a system, so match the fitting to the pipe your spec calls out rather than mixing galvanized and black in the same run.
7) How much does one of these 3/4 x 1/2 x 1/2 tees weigh for a takeoff?
0.47 lbs each. Handy if you are pricing freight or figuring hanger loads on a long threaded run with a lot of fittings.
8) What is the manufacturer part number for this ASC galvanized tee?
ASC Engineered Solutions part number 311038806, the 3/4 x 1/2 x 1/2 galvanized malleable iron tee.
