ASC Engineered Solutions 311047807 – Frequently Asked Questions
1) What are the port sizes on the ASC Engineered Solutions 1-1/2 x 3/4 x 1-1/2 galvanized malleable iron tee?
It's a reducing tee: the two run ends are 1-1/2 inch and the branch outlet is 3/4 inch. That lets you carry a 1-1/2 inch line straight through and pull a 3/4 inch branch off the side without adding a bushing.
2) Are all three openings on this galvanized malleable iron reducing tee female threaded?
All three openings are FPT, so each one takes male pipe thread. Threads are cut to ASME B1.20.1 (NPT), which means it mates with standard threaded steel or galvanized pipe and with any NPT nipple or male adapter.
3) Can I use this tee on a fire sprinkler line?
Yes, the fitting is UL/FM approved, which is what an AHJ looks for on fire protection piping. It is a standard weight (STD) galvanized malleable iron fitting dimensioned and pressure rated to ASME B16.3.
4) Is the galvanizing hot dip, and will it hold up outdoors or in a wet system?
The coating is applied to ASTM A-153, the hot dip galvanizing standard for iron and steel hardware, over a malleable iron body made to ASTM A-197. That is the usual choice for wet sprinkler risers, exposed exterior runs, and damp mechanical rooms where black iron would rust out.
5) Which port is the 3/4 inch branch on this reducing tee?
The 3/4 inch is the branch outlet, sitting between two 1-1/2 inch run ends. Orient the 1-1/2 inch ports along the main and take the 3/4 inch off the side for a drop, a gauge, a drain, or a fixture takeoff.
6) Do the laying lengths match other brands of malleable iron tees?
Dimensions follow ASME B16.3, the same standard other malleable iron fitting makers build to, so center to end dimensions interchange with any B16.3 Class 150 tee of the same size combination. Your cut list does not change if you swap brands.
7) Will this galvanized tee fit a black iron pipe system?
Mechanically yes, the NPT threads are the same. But joining galvanized to black steel is normally avoided on the same wet line because of the dissimilar metal corrosion at the joint. For a galvanized system it drops straight in.
8) How much does this 1-1/2 x 3/4 x 1-1/2 malleable iron tee weigh?
1.51 lbs each. Useful when you are figuring hanger spacing and support loads on a threaded run with several fittings in it.
