The B436 is the workboat take on a small tank: 13 gallons in a shell that ships at 71 lb, meaning most of what you are buying is wall. Small tanks on hard-used boats fail at the fitting bosses when the wall is thin and the vibration is constant; this molding answers that with sheer material.
Those 13 gallons can be drinking water or waste. As a dual-role B-series molding the role is fixed by the fittings, which Ronco installs per order in Tustin, California - spin-welded or thread-mounted at the positions you mark, from the same shop that has molded tanks since 1974. Print the drawing below, mark it against your actual plumbing, and use the on-page fitting planner to pick sizes; on a tank this small, one well-placed fitting beats two compromised ones.
Full, it carries about 108 lb of water. If you want the same capacity in a lighter shell, or a different footprint entirely, the small end of the boat tank category is worth a scan, and every Ronco molding we stock is on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
