ASC Engineered Solutions 311042808 – Frequently Asked Questions
1) What are the three outlet sizes on this ASC galvanized malleable iron reducing tee?
It's a 1-1/4 x 1-1/4 x 1/2 inch tee: the run is 1-1/4 inch on both ends and the branch reduces to 1/2 inch. All three openings are female pipe thread (FPT), so it takes male-threaded pipe nipples on every port. Part number 311042808.
2) Will this tee thread onto standard NPT pipe and nipples?
Yes. The threads are cut to ASME B1.20.1, which is the standard NPT taper thread spec, so it mates with ordinary threaded steel or galvanized pipe of the matching size. Use pipe dope or PTFE tape on the taper as usual. The fitting dimensions follow ASME B16.3 for malleable iron threaded fittings.
3) Is this a Class 150 standard fitting or an extra-heavy tee?
Standard pattern (STD), pressure rated per ASME B16.3. Extra-heavy malleable iron fittings are a separate, thicker-wall pattern; if your spec calls for Class 300 extra-heavy, this standard tee is not the right part.
4) Can I use a galvanized malleable iron tee on a wet sprinkler or water line, or should I use black iron?
The galvanized coating is applied to ASTM A-153 (hot-dip on iron hardware), which is what you want for wet service, damp mechanical rooms, and exposed runs where black iron would rust. Black malleable fittings are the usual pick for dry gas and oil lines. Body material is malleable iron to ASTM A-197.
5) Do I need a bushing to get from 1-1/4 inch down to 1/2 inch with this fitting?
No. The reduction is built into the tee, the branch port is already tapped 1/2 inch FPT. That saves you a 1-1/4 x 1/2 reducing bushing and one more leak path. Run ports stay 1-1/4 inch FPT.
6) How much does this 1-1/4 x 1-1/4 x 1/2 galvanized tee weigh for takeoff and hanger sizing?
1.19 lbs each. Handy when you're totaling fitting weight on an overhead threaded run or pricing freight on a bulk order of branch fittings.
