Does anyone recognize this part?

I don't remember taking this out of anything but who knows, it may have fallen out and I didn't see it until now. It was sitting on the table next to my other junk for the bike and I saw it sitting on the kitchen counter before. I figure it was my room mates parts cause he is working on his quad so I disregarded it but he put it on the table. Now I want to make sure it doesn't go to anything in particular.

I don't really want to make a big deal out of this but if anyone recognizes it then let me know but I wouldn't go detective mode on it.

 

It looks like a washer that goes in a garden hose.

 

That's probably it! It probably goes to the garden hose nozzle I brought in last week. Case closed.

 

yup just had some in my hand

 

I just had one today in my junk drawer while looking for a tire pressure gauge.
that's a cheap one. Toss it and get one of those red rubber ones, those plastic ones always leak.

 

I was washing my truck the other day and found the samething on my bumper. True story. Good thing I found it cause my pressure washer was leaking.

 

I hate when you find things in your work area and wonder if you left something off when reassembling something. A good argument for a neat workspace....not that that will happen to me anytime soon.
