ASC Engineered Solutions 311041008 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 1 x 3/4 x 1/2 galvanized malleable iron tee, and which one is the branch?
The reducing tee has a 1 inch run opening, a 3/4 inch run opening, and a 1/2 inch opening, all female threaded. The convention for a reducing tee written 1 x 3/4 x 1/2 is run x run x branch, so the 1/2 inch port is the branch outlet and the 1 inch and 3/4 inch openings are the straight run. That lets you step 1 inch line down to 3/4 inch while taking a 1/2 inch takeoff at the same fitting.
2) Are all three openings on this reducing tee female threaded, or is one a male end?
All three openings are FPT, female pipe thread. There is no male end on this fitting, so it threads onto male pipe nipples or male-end adapters on every port. Threads are cut to ASME B1.20.1, the NPT standard, so they mate with standard tapered pipe thread and need thread sealant or PTFE tape.
3) Can I use this galvanized malleable iron tee on a fire sprinkler line?
This tee is UL/FM recognized, which is the listing fire protection contractors and AHJs look for on threaded sprinkler piping fittings. It is standard (STD) pattern galvanized malleable iron built to ASME B16.3, with NPT threads to ASME B1.20.1. Galvanized is the usual choice for dry and preaction systems where corrosion inside the pipe is a concern. Confirm the system pressure against the B16.3 rating for the class and size you are running.
4) What does the galvanized coating on this malleable iron tee meet, and will it hold up outdoors?
The zinc coating is applied to ASTM A-153, the hot-dip galvanizing standard for iron hardware, over a malleable iron body made to ASTM A-197. That is the coating spec typically called out for exterior and wet-service threaded fittings, and it is why galvanized malleable iron gets used on outdoor gas, air, and water lines rather than black iron.
5) Can I thread copper or PEX directly into this galvanized tee?
No. Every port is female NPT on a galvanized malleable iron body, so it accepts threaded steel or iron pipe and threaded adapters only. To land copper or PEX on it, use a male-threaded transition adapter of the correct size, and on copper use a dielectric union or dielectric nipple to keep the copper from contacting the galvanized iron.
