Gravity feed ATO

[jackde]

Wanting to build small acrylic tank for a gravity feed ATO. My question is does anyone know to find a small 1/4" bulkhead to run the water line to the valve?

Most hobby vendors that sell RO components have them:

I've bought them at big box home improvement stores, too.

I ran into this same problem trying to set up a 55 gallon food grade barrel as a gravity fed ATO tied into my water change station, those JG adapters won't work too well unless you replace the metal nut and find some sort of gasket material or a small o-ring. The best solution I found was 1/4" uniseals from Savko, they fit the 1/4" RO lines perfectly and they're cheap.
