An 83 lb blank holding 23 gallons: the B499's spec sheet reads like a small tank built to a big tank's standard, and that is exactly what it is. Ronco pours wall into this molding, which makes it the pick for commercial hulls, charter boats, and any installation where the tank will outlive several owners' ideas about maintenance.
It is a dual-role marine shell. With fresh-water fittings it serves as an FDA-compliant potable tank; ordered as a holding tank the identical molding takes gray or black waste. The contents at full come to about 192 lb - less than the shell-plus-water total suggests at a glance, because so much of this tank's mass is the tank.
Fittings are installed per order at the Tustin, California plant, spin-welded or threaded precisely where you mark them, as Ronco has done since 1974. Print the drawing below, mark your penetrations, and finalize them in the on-page fitting planner.
Given the shell weight, price your lane with the freight cost estimator, then browse the rest of the marine line under boat tanks or the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
