Uniseal tank thickness

[Project_Mayhem]

@Peggie Hall HeadMistress had recommended Uniseals to add a pump out to a portapottie. I'm in the process of adding a fill port to my fresh, flush tank on my portapottie. I have everything, including a Uniseal but noticed that the minimum tank thickness is 1/8". My blow molded tank is much thinner. Will this be an issue? I can cut out a piece of plastic as a spacer. I'm pretty confident that BedIt will work well as a seal between the two pieces of plastic. I attached a garden hose to the bottom of a 5 gallon bucket and BedIT worked well.

Note: This tank contains freshwater that is used for the head only. It's roughly 4-5 gallons so if it leaks, it's not catastrophic

Uniseal got back to me. They said as long as the tank wall is stiff enough to hold it's shape it should be good. Adding thickness won't hurt either

Uniseal was a great and very inexpensive option for me repairing a leaking fitting on a black tank.

You can always put a rubber gasket under the flange on the outside of the tank.
