I have some 6 quart sterilite containers that I am trying to make into fry racks using some nylon adapter elbows with female fittings and an O-ring. The problem that I have is that I can't get the seal to be water tight, and I keep getting a leak. Someone told me that silicone won't bond to the plastic bins, so I don't have any idea how to make it water tight. Anyone that has ever done anything like this have any ideas? Thank you in advance.
