ASC Engineered Solutions 311038202 – Frequently Asked Questions
1) Which ports are 3/4 inch and which one is 1/2 inch on this ASC reducing tee?
The ASC Engineered Solutions galvanized malleable iron tee runs 3/4 x 3/4 x 1/2. The two run ends are 3/4 inch and the branch outlet is 1/2 inch, so you keep a 3/4 inch line straight through and take a 1/2 inch drop or riser off the side. All three openings are female pipe thread.
2) Is this tee UL Listed and FM Approved for fire sprinkler piping?
Yes, it carries UL/FM recognition, which is what lets it be used on fire protection piping where the authority having jurisdiction requires listed fittings. It is Class 150 standard pattern malleable iron with pressure ratings per ASME B16.3.
3) Galvanized or black malleable iron tee, which should I use?
This one is hot dip galvanized to ASTM A-153 over malleable iron made to ASTM A-197. Use galvanized where the line sees moisture or is outdoors, on wet sprinkler and service water piping, or where the existing pipe is galvanized. Black iron is the usual pick for dry gas and dry sprinkler work. Matching fitting finish to pipe finish keeps you out of dissimilar metal trouble.
4) Do I need a bushing to get a 1/2 inch branch off a 3/4 inch line?
No. Because the branch is already cast at 1/2 inch FPT, this reducing tee takes the step down for you, so a 3/4 x 3/4 x 3/4 tee plus a 3/4 x 1/2 bushing is not needed. That means one less joint to seal and less restriction in the branch. Just thread a 1/2 inch nipple straight into the outlet.
5) What is the part number and weight on the ASC 3/4 x 3/4 x 1/2 galvanized tee?
Order it by MPN 311038202. Each fitting weighs about 0.5 lbs, which matters if you are pricing out freight on a bulk order of threaded fittings or figuring hanger loads on a long run.
6) Can I use this malleable iron tee on a potable water line?
It is a galvanized malleable iron threaded fitting for plumbing service, built to ASTM A-197 with ASTM A-153 hot dip galvanizing. Galvanized iron is commonly run on water service and older domestic water systems. For potable work, confirm your local code still permits galvanized steel piping on new installs, since many jurisdictions now restrict it.
