The B432 packs 40 gallons into a 28 x 23 x 16 inch block - the compact-footprint answer when your bay is short but has some height to work with. Where the long slim tanks in this series chase length, the B432 goes the other way: a dense, nearly square shape that drops into a cockpit locker or a transverse bay ahead of an engine.
It is a dual-role B-series molding, so the same shell covers fresh water duty or gray/black waste holding; the fittings decide, and you decide the fittings. Print the drawing below, mark the positions that suit your hose runs, and Ronco spin-welds or thread-installs them to the marks before shipping. The on-page fitting planner is there to translate your plumbing into an order.
At 35 lb bare it is an easy tank to handle, but full it holds about 334 lb of water in a small footprint - concentrated load, so use solid backing. Rotomolded in Tustin, California by Ronco, tank builders since 1974. Related shapes are in the boat tank range and the RV water tank range; everything else is on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
