ASC Engineered Solutions 311044804 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 1-1/4 x 1/2 x 1 galvanized malleable iron tee?
It's a reducing tee with three different openings: 1-1/4 inch, 1/2 inch, and 1 inch, all female pipe thread. The 1/2 inch port is the branch takeoff, so it's the fitting to use when you're pulling a small drop or gauge line off a larger run and the run itself steps from 1-1/4 to 1 inch. If all three of your connections are the same size, you want a straight tee instead.
2) Will this galvanized tee thread onto standard black or galvanized steel pipe?
Yes. All three openings are FPT cut to ASME B1.20.1, the NPT taper thread standard, so it mates with any standard threaded steel or iron pipe of the matching size. Use pipe dope or PTFE tape on the male threads as usual.
3) Is this tee UL Listed and FM Approved for fire sprinkler work?
Yes, the fitting carries UL/FM recognition, which is what an inspector looks for on threaded fittings in a wet or dry sprinkler system. It's a standard weight malleable iron tee built to ASME B16.3 for both dimensions and pressure class.
4) Is a galvanized malleable iron tee OK for outdoor or damp locations?
The galvanized coating is applied to ASTM A-153, the hot-dip spec for hardware, which is what makes this suitable for exposed, damp, and outdoor runs where a black iron fitting would rust. The body itself is malleable iron to ASTM A-197. For potable water service, check your local code, since galvanized steel systems are restricted in some jurisdictions.
5) Which opening is the 1/2 inch branch, and does orientation matter when I order?
On a reducing tee the sizes read run-run-branch, so with 1-1/4 x 1/2 x 1 the two ends of the straight run are 1-1/4 and 1 inch and the 1/2 inch is the branch outlet coming off the side. No handing to worry about, it's symmetrical about the branch, but you do need to know which leg of your run is the larger one before you sweat over fit.
6) How much does this 1-1/4 inch galvanized tee weigh for freight and hanger sizing?
0.94 lbs each. Light enough that a single fitting adds nothing meaningful to a hanger load, but useful if you're pricing a pallet of them or figuring total weight on a long threaded run.
7) What is the ASC Engineered Solutions part number for this reducing tee?
The manufacturer part number is 311044804, an ASC Engineered Solutions galvanized malleable iron reducing tee, 1-1/4 x 1/2 x 1, all FPT.
