ASC Engineered Solutions 311043202 – Frequently Asked Questions
1) What size openings does the ASC 1-1/4 x 1 x 1-1/4 galvanized malleable iron tee have?
It's a reducing tee: the two run ends are 1-1/4 inch and the branch outlet is 1 inch. All three openings are female pipe thread (FPT), so it takes male threaded pipe nipples on every port. Model 311043202.
2) Is this galvanized tee UL listed and FM approved for fire sprinkler piping?
Yes, the 1-1/4 x 1 x 1-1/4 galvanized malleable iron tee carries UL/FM recognition, which is what inspectors look for on wet and dry sprinkler branch lines. It's a standard (STD) class fitting dimensioned to ASME B16.3.
3) Is a galvanized malleable iron tee OK to use on a potable water or wet system line?
The galvanizing is a hot-dip zinc coating to ASTM A-153 over malleable iron made to ASTM A-197. That coating is what makes it suitable for wet service and damp locations where plain black iron would rust, including galvanized water lines and wet sprinkler systems. For gas and dry interior work, black malleable iron is the usual choice instead.
4) Do I need a bushing to drop from 1-1/4 inch pipe down to a 1 inch branch?
Not with this fitting. The reduction is built into the tee, with the 1 inch branch already formed at the outlet, so you thread 1 inch pipe straight into the branch and 1-1/4 inch on the run. That saves a reducing bushing and one more leak path.
5) Which way does the reduction sit on a 1-1/4 x 1 x 1-1/4 tee?
Read the sizes in order: run end, run end, branch. Here the two straight-through ends are both 1-1/4 inch and the 1 inch is the side outlet. If you need the reduction on the run instead of the branch, that's a different fitting, so check the size sequence before ordering.
6) What pressure class is this ASC tee?
Standard (STD) class, with the pressure rating governed by ASME B16.3, the same standard that sets the fitting's laying dimensions. Since B16.3 dimensions are standardized, it interchanges with any other B16.3 standard-class 1-1/4 x 1 x 1-1/4 malleable tee in an existing run.
7) How much does this fitting weigh for a takeoff or freight estimate?
1.19 lbs each for the 1-1/4 x 1 x 1-1/4 galvanized malleable tee. Handy if you're pricing out a hanger and support load or a bulk order for a sprinkler or process run.
