Description
The Custom Roto-Mold 42 Gallon Marine Water Tank (Part# MW-464) is purpose-built for mobile potable water storage in marine vessels, RVs, trailers, and mobile food units. With its squat rectangular form, this tank is ideal for floor-mounted installations or under-bench applications where vertical clearance is limited but wide horizontal space is available.
Engineered through advanced rotational molding, this tank features a seamless one-piece body made from FDA-compliant polyethylene. Its durable construction resists splitting, punctures, and leaks even under constant motion or extreme vibration—perfect for mobile use in demanding environments.
The MW-464 is supplied in a blank configuration, allowing users to install fittings exactly where needed. Whether your project calls for top-fill, side-drain, or vented configurations, this tank offers full customization potential to suit your specific plumbing setup.
