For sale: Eshopps Prodigy L Slimline Overflow Box - used - includes new drain bulkheads $115 located near San Diego/Riverside border $135 shipped

How many gaskets / orings are suppose to come with this overflow box? Mine only came with one that i used on the inside of the tank. However im weary about inside the box not having an additional gasket before the nut. Does this unit really only come with a single gasket?

I started a build thread for a 300 gallon peninsula in Oct of 2019 aaaaaaand...still no saltwater in the house. After going back and forth on this idea, my wife and I finalized the plan to put a 40 breeder in the 5th baby’s nursery. Yah, five children. It gets better...the oldest is just barely...
