ASC Engineered Solutions 310064209 – Frequently Asked Questions
1) What are the three port sizes on the ASC Engineered Solutions 1-1/4 x 1 x 1-1/4 black street tee?
The run is 1-1/4 inch on both ends and the branch is 1 inch, so it reduces only at the branch outlet. Because it's a street tee, one end is male pipe thread (MPT) and the other two are female pipe thread (FPT). That male end threads straight into a female fitting without a close nipple.
2) Can I use this black iron tee on a gas line?
Black malleable iron fittings to ASME B16.3 with NPT threads are the standard choice for black iron gas piping, and this one is standard pattern (STD) class. It is a black finish, uncoated fitting, so it is not intended for potable water where a galvanized or brass fitting would be used. Always follow your local fuel gas code and inspector for the specific installation.
3) Is this tee UL Listed and FM Approved for a fire sprinkler system?
Yes, it carries UL/FM recognition, which is what an inspector looks for on a wet or dry sprinkler branch line. Pressure rating follows ASME B16.3 for a standard class malleable iron fitting.
4) What grade of malleable iron is this fitting made from?
It's cast to ASTM A-197, the cupola malleable iron spec used for threaded pipe fittings. That's the material callout an engineer or plan reviewer will want to see on a submittal, alongside the ASME B16.3 dimensional and pressure standard.
5) What is the manufacturer part number for this ASC street tee?
ASC Engineered Solutions part number 310064209, the 1-1/4 x 1 x 1-1/4 black malleable iron street tee. That's the number to quote when matching an existing spec or reordering the same fitting across a job.
6) How much does this 1-1/4 x 1 x 1-1/4 street tee weigh?
About 1.34 lbs each. Worth knowing if you're pricing freight on a bulk fitting order or calculating hanger loads on a long horizontal run.
