A while ago I bought some of those #5 o-rings on the advice of members of this group. My experience was that they were too big - I couldn't squeeze the (alpha) pot with the o-ring on it into the 3/8 hole. It's quite possible that home depot had them labeled wrong though. So when you're at the store, pick up some smaller ones just in case - they're cheap.
