Since 1974, Ronco Plastics has rotationally molded polyethylene tanks in Tustin, California, and the RVB376 is a current example of that catalog: a 45 gallon class fresh water tank for RV service, shipping at approximately 90 pounds. The light-duty potable rating suits it to the drinking water system of a motorhome, fifth wheel, or custom coach.
The resin is natural FDA-compliant polyethylene with no colorant, so the wall remains translucent and the water level is visible straight through it, a simple gauge that never fails. Rotomolding forms the RVB376 as one seamless piece; with no welds, joints, or bonded sections, the wall has no built-in weak points to open up over years of frame flex and washboard roads.
Every RVB376 is drilled and fitted to its buyer's plan. Ronco installs spin-weld or threaded fittings located per the customer's specification, its standard practice, so the tank shows up with connections matching your fill, vent, and supply runs. When a drawing is displayed it depicts the blank molding. OneSource Plastics carries this tank as an authorized Ronco Plastics dealer.
