ASC Engineered Solutions 310044607 – Frequently Asked Questions
1) What are the port sizes on the ASC Engineered Solutions 1-1/4 x 1/2 x 1-1/4 black malleable iron tee?
It's a reducing tee: the two run ends are 1-1/4 inch and the branch outlet is 1/2 inch. All three openings are female pipe thread (FPT), so it drops into a 1-1/4 inch threaded run and gives you a 1/2 inch takeoff for a drop, gauge, drain, or small branch line without adding a bushing.
2) Is this black iron tee acceptable for a fire sprinkler system?
It carries UL/FM approval, which is what an AHJ looks for on fire protection piping. It's a standard-weight (STD) malleable iron fitting made to ASTM A-197 with ASME B16.3 dimensions and pressure ratings. Confirm the working pressure of your system against the B16.3 class rating for the size before you commit.
3) Can I use a black malleable iron tee on a potable water line?
No. Black malleable iron fittings are for gas, fire protection, steam, and non-potable service. The black finish is a mill coating with no corrosion protection for wet potable use. For potable water, go with a galvanized, copper, brass, or CPVC fitting instead.
4) What is the difference between a standard and extra heavy malleable iron tee?
This one is standard weight, marked STD. Standard 150 class malleable iron covers most gas, sprinkler, and low pressure applications. Extra heavy (300 class) has thicker walls and a higher pressure rating for high pressure steam or heavier industrial service. If your spec calls out 300 class, a STD fitting won't satisfy it.
5) Do I need a bushing to get a 1/2 inch takeoff from 1-1/4 inch pipe?
Not with this fitting. The branch is already reduced to 1/2 inch FPT, so it saves you a 1-1/4 x 1/2 reducing bushing and one extra joint to seal. Fewer joints means fewer leak paths on a gas or sprinkler run.
6) How much does this 1-1/4 x 1/2 x 1-1/4 tee weigh for shipping or hanger load?
1.04 lbs each. Worth noting when you're sizing pipe supports on a long threaded run, where fitting weight adds up across multiple takeoffs.
7) What is the part number for the ASC Engineered Solutions 1-1/4 x 1/2 x 1-1/4 black tee?
The manufacturer part number is 310044607, an ASC Engineered Solutions black malleable iron reducing tee with 1-1/4 inch run ends and a 1/2 inch branch.
