terminal covers (Rubber)

[BTBuck1]

I remember when I was a kid fishing around behind my dads stereo equipment seeing rubber little "booties" or covers over the RCA terminals that weren't in use, he had them in red, white and black and they just slipped over the rca jacks and kept dust out and corrosion down i'd imagine.

My question is, does anyone know where to get these? I think this is something I'd like to have because i've noticed my terminals on my equipment without cables connected looks a little corroded already and the equipment isnt that old. Just peice of mind thing I guess. but i'm sure they're cheap and it'd be a nice finishing touch (like banana plugs kinda) to my system.

If anyone knows what they are called or where to get them that would be great...thanks!
