The Ronco Plastics B498 molds 23 gallons into a compact, nearly square-sided body, a 32 lb shell that fits where long tanks cannot and stands where flat tanks fall short. It is the utility infielder of the small B-series sizes.
Dual-role, as always in this family: the fittings you order make it either a fresh water tank, with food-contact polyethylene fit for drinking water, or a gray or black waste holding tank. Ronco installs the fittings per order, spin-welded or threaded at your specified locations, so the compact body arrives with its ports aligned to your actual hose geometry.
Filled, it holds about 192 lb of water at 8.34 lb per gallon. Print the dimensioned drawing below, check the squarish footprint against your opening, and finish the specification in the on-page fitting planner.
Molded in Tustin, California by Ronco Plastics, running since 1974. The neighboring sizes in the marine tank line flank it closely on both sides, the RV water tanks cover wheeled applications, and the freight cost estimator answers the shipping question in seconds. OneSource Plastics is an authorized Ronco Plastics dealer.
