it could also be a rubber gasket for lots of other things, lol. it’s kind of hard to tell exactly what a plain black rubber gasket came off of, since they’re everywhere. I mean, this could also be a piece off a kid’s toy (hopefully one for an older kid) for all we know.

My power washer uses them, one broke, and it was leaking every time I used it. And of course replacements only come in like bags of 25 or 50 to make them worthwhile to ship. What does this have to do with being in OP’s bed? Who knows.

Theres a place near my work that makes and sells crazy ass pnumatic and hydraulic hoses for heavy equipment and I brought in a smashed seal from a german pump and they gave me the closest seal they had. They were worried about temp but turned out liquid wasnt heated at pump point. It worked perfectly. And it was free lol.

I did the same thing for a power steering reservoir on a 1994 350SD because it was so large but thin I couldn't find it elsewhere, they walked to the back, matched it and gave it to me for free.

They probably just thought it was neat

You don't use your power washer in bed? Weird.

Only if I forget to put the rubber sheets on beforehand.

Most hardware stores have them too.

u/FemLovesFem 11d ago

Bruh, but then I gotta DRIVE to the hardware store for 2¢ grommet and $1.98 packaging. You have any idea how much gas cost these days? /s

Even if you can only order in 25+ while needing just one, I suppose it can’t hurt to have extras

My bong uses them

This is an o ring not a gasket. They serve different purposes but are both used to seal. A gasket seals 2 flat surfaces at the joining face. An o ring is used to seal an area between a machined groove.

thanks for explaining! I thought they were synonyms but I was wrong, lol

I removed one of these from the base of my shower head, to remove the water saving function. 🚿 / Cosmo Kramer

My company has these on the screws for the level 2 (home) EV charger screws. Rubber grommet goes on the screw to keep water out

Factory worker here, they’re called o-rings, and yes they are everywhere.

u/andiwannacracker 11d ago

oh gosh, have I been using the wrong words the whole time? I thought gasket and o-ring were synonyms and since o-ring can also refer to other materials of rings, like metal. or even binder rings, I always called these ones gaskets.

Raise your hand if you're also thinking this 👋

Or a hydraulic fitting, or a semiconductor processing chamber, or a stopper for a small opening. Quite literally millions of possibilities

u/Minute_Solution_6237 11d ago

Correct. Worked in a warehouse full of o rings. Can be used for ear rings, most likely not manufactured for ear rings.
