Okay I will give you guys a hint. it has to do with vibration (No tiga you sick bastard, not that kind)
ooh ooh it is the thing with an offset weight in it and it goes in your cellphone and makes it vibrate
I'm thinking Martin is right. It's like the feet on my old Technics SL-1200 turntables that isolated the turntable from the vibration of the sound system, except tiny. Maybe used in disc drives?
I used to sell Clippard Minimatic cylinders. Their smallest was a 5/32" bore. Looks just like it. Gonna try to post a pic - it's a pdf though. I don't know if it will post. ETA: It wouldn't show up. Click this link to see it. ETA#2. Found a pic! So, if it's not this, it's something along the same lines.
Close enough. It is some doowobbly that cuts down reverb in circuit boards. I will post the link to the website when I get back home. If I still have one.
