They came out today and I asked them what the fitting is. They said
it is called a "posilock" fitting. It is used because the old steel
gas lines that came into buildings are no longer used for gas supply.
Instead, the steel pipe is now used as a conduit. Inside the steel
conduit is a plastic gas supply line that comes in from the street. The
posilock fitting connects the plastic gas supply line to the gas
line that is inside the building that goes to the meter.

I did a bunch of Google searches on posilock etc. and I still
couldn't find too much additional information, but here's what I did
find: "posilock transition fitting"

"The posilock seals together the larger plastic pipe from the street
to a smaller metal pipe in the basement of a home or business."

Interesting.

Here's link to Inner-Tite who does list the trademark but I see no
hint of the particular product/fitting. One might presume it was
recalled/abandoned as a not-so-good idea, maybe.

At least there's a rational explanation for what it looks like
although might be some reason to be at least vigilant if not
necessarily nervous.

My guess is that after the lawsuit, Inner-Tite decided to get out of the
business of selling the fittings. I would love to take one apart and see
exactly how it works, but of course, I won't be doing that.
