Just kidding yah - couldn't help it!  LOL Not sure what you're asking, but they are a threaded sleeve with a plug gasket sealing surface at the top. Is that what you mean? |
Haha. Good one, Dale. I was thinking of the smaller ones 3/8" for intake repair.
I guess going by pictures on the internet is not the best plan of attack, but they appeared to have a closed bottom which was confusing me as to their usage for the exact reasons you joked about.
