100 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-462)

Description

The Custom Roto-Mold 100 Gallon Marine Water Tank (Part# MW-462) is expertly engineered to meet the rigorous demands of potable water storage in marine vessels, RVs, food trucks, and specialty mobile units. With its long, rectangular footprint and moderate height, it offers ample capacity while still fitting within common installation areas like under bunks, decks, or service compartments.

Constructed using rotational molding technology, this tank features a seamless, one-piece body that resists leaks, splitting, and structural fatigue. Its design ensures a long service life even in high-vibration or extreme temperature environments. The tank is made from FDA-approved polyethylene resin, fully compliant with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it ideal for potable water storage.

The MW-462 ships blank, meaning no fittings come pre-installed, giving installers complete flexibility to configure ports and connections to match custom plumbing layouts. Whether you’re retrofitting a boat or customizing a mobile water delivery setup, this tank provides the capacity and reliability needed for mission-critical applications.
