ASC Engineered Solutions 310521208 – Frequently Asked Questions
1) What size openings does the ASC Engineered Solutions 1 x 1 x 3/4 black malleable iron tee have?
It's a reducing tee: both run ends are 1 inch and the branch outlet is 3/4 inch. All three openings are female pipe thread (FPT), so it threads onto male-threaded pipe nipples, not onto female ends. Use it where you run 1 inch line and need to drop a 3/4 inch branch off it.
2) Is this black malleable tee UL listed and FM approved?
Yes, the 1 x 1 x 3/4 extra heavy black tee carries UL/FM recognition, which is what fire protection inspectors look for on sprinkler and fire main piping. Dimensions are per ASME B16.3 and the iron is per ASTM A-197.
3) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron is the wrong material for potable water, it will rust and discolor the water. Black fittings like this one are for gas, air, fire protection, and similar non-potable service. For water supply, use galvanized, copper, brass, or CPVC fittings instead.
4) What does XH mean on a malleable iron fitting, and when do I need it instead of standard?
XH is extra heavy, meaning thicker walls and a higher pressure rating than a standard (Class 150) malleable fitting of the same size. Pressure ratings follow ASME B16.3. Spec XH where the line pressure, mechanical stress, or the job spec calls for more than a standard black fitting handles; for ordinary low-pressure gas or air runs, standard weight is usually what's called out.
5) How much does the 1 x 1 x 3/4 extra heavy tee weigh?
About 1.33 lbs each. Worth knowing if you're figuring hanger spacing and support loads on a long run, or estimating freight on a bulk order of fittings.
