First time seeing one of these connections, and I am not sure how to report on it.
They are prohibited by both IPC and UPC because they tend to leak. Ask your AHJ to verify.

I would check with your local AHJ if those fittings are approved for use in your area.
They are not in some locals.

Emergency use or utilities. Proper saddles are too expensive for home use IMO.
It looks like there is chocolate already leaking out:
That was my first thought too Larry, but it is some type of sealant. Tasted like banana…

OMG!!! Hilarious!!!
Me as well, John.
It appears manufactured as a cast iron transition T fitting for the main soil and waste vent, to the soil pipe that connects to a sanitary lateral to sewer pipe. No leaks.
Transition fittings are used to connect pipes of different materials, such as PVC to copper or ABS to cast iron.
Personally, I see no issues but will await for the to chime in as I read the strings.
Oatey® Saddle Tee Kits are designed for tapping into a 3 in. or 4 in.
