ASC Engineered Solutions 310045208 – Frequently Asked Questions
1) Which opening on the 3/4 x 3/4 x 1-1/4 black malleable iron tee is the bigger one?
It's a reducing tee with two 3/4 inch ends and one 1-1/4 inch end. The size sequence runs 3/4, 3/4, 1-1/4, so the 1-1/4 opening is the branch, and the two run ends take 3/4 inch pipe. All three are female pipe thread.
2) Can I use this black malleable iron tee on a fire sprinkler line?
It carries UL/FM approval, so it's acceptable for fire protection piping where a listed fitting is required. It's standard pattern malleable iron to ASME B16.3, with ASTM A-197 material. Confirm the system pressure against the B16.3 standard-class rating for the size.
3) Is this a standard or extra heavy (150 vs 300) malleable iron tee?
Standard pattern. The strength class is listed as STD, which is the Class 150 malleable iron fitting under ASME B16.3. If your spec calls for Class 300 extra heavy, this is the wrong fitting.
4) Black or galvanized tee for a gas line?
This one is black finish malleable iron, which is the usual choice for natural gas and fuel gas piping and for closed-loop steam or hydronic work. Galvanized is used on domestic water. Black iron should not be run on potable water lines.
5) Do I need a bushing to branch up from 3/4 inch pipe to 1-1/4?
Not with this fitting. The 1-1/4 inch FPT outlet is cast into the tee, so you branch up directly without stacking a coupling and bushing. Fewer joints, fewer leak paths, and the outside dimensions stay within ASME B16.3 so it drops into a dimensioned layout.
6) How much does the 3/4 x 3/4 x 1-1/4 black tee weigh for takeoff?
0.9 lbs per fitting. Useful if you're calculating hanger spacing or support loads on a run of these.
7) What is the ASC part number for this black iron reducing tee?
Manufacturer part number 310045208 from ASC Engineered Solutions, a 3/4 x 3/4 x 1-1/4 black malleable iron tee.
