The Ronco Plastics B412 closes out this run of the B-series with 18 gallons in a molding that ships at 79 lb, a strikingly heavy wall for the capacity. That mass makes it the 18 gallon tank for hard service: open boats, work rigs, installs where the tank takes abuse the rest of the system never sees. Dual-role like the whole family, it finishes as a potable food-grade fresh water tank or a gray or black waste holding tank per the fittings ordered.
Full, it carries about 150 lb of water at 8.34 lb per gallon, which means this tank nearly matches its own contents in wall mass. Ronco also molds lighter shells at this capacity; choose by duty, not just by gallons.
Fittings are installed per order, spin-welded or threaded at your marked positions. Print the drawing below, mark where the plumbing lands, and finish the spec with the fitting planner on this page. Ronco has built tanks this way in Tustin, California since 1974.
