The B268 is a square-plan 5 gallon molding, 12.25 x 12.25 x 8.25 inches - a tank with the footprint of a floor tile. Its symmetry is its feature: with equal sides it fits its niche in any rotation, so the fitting layout, not the tank shape, decides the orientation. That flexibility matters most in the cramped corners this size lives in.
Five gallons runs a sink for a weekend, feeds a coffee station in a van, or catches gray water from a single drain - and as a B-series dual-role blank, the B268 does whichever you order. Fresh-fitted, the food-grade polyethylene is potable-safe; waste-fitted, it is a fixture-scale holding tank. Print the drawing below, mark your fitting locations, and use the on-page fitting planner to spec the spin-weld or threaded fittings Ronco installs to your marks.
Eight pounds empty, about 42 lb full, molded in Tustin, California like everything Ronco has made since 1974. When five gallons stops being enough, the next steps are in our RV water tank category and boat tanks, with the full line on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
