I picked up a bulkhead kit from BargainFittings.com recently and in putting it together found the included washer doesn't fit flush against my orange 10g cooler wall due to how the cooler wall is molded. When put together there is a bit of play due to this washer not sitting flush against the wall so I assume it won't hold water at all.
I picked up a zinc plated washer from homedepot that is much larger and appears to do the job. Now i know this type of metal should never come into direct contact with beer but with it being placed on the outside, it should be safe right?
The o-ring is on the inside which should be what is stopping the liquid from escaping. Otherwise, wouldn't inside of the cooler where the insulation is fill up with the sweet nector?
