Review on ZAOJIAO Bulkhead Connector Connect Reverse by Jeff Rubio

The description never mentions this, but the shank is only 2/3 threaded. So the fitting can only go through 3/8" of the bulkhead and still allow you to compress the gasket with that nut. Also, there is no washer for an airtight seal. It looks like it will work for those with bulkhead/ Wall work that's thin enough, and it's probably above any waterline. But in my case, I tried running a fill line into a 1/2" mix tank. It does not work. See image. streaming.
