Description
The Custom Roto-Mold 57 Gallon Marine Water Tank (Part# MW-418) is designed to provide safe and efficient potable water storage in marine, RV, and mobile utility applications. Its ultra-low-profile layout makes it an excellent solution for underfloor or shallow compartment installations, especially where vertical clearance is extremely limited.
Constructed using rotational molding technology, the tank features a seamless, one-piece polyethylene body that offers superior structural integrity. This manufacturing method helps the tank resist cracking, leakage, and deformation under stress, making it well-suited for use in mobile, high-vibration environments and harsh marine conditions.
To ensure the safety of your potable water, this tank is made with FDA-approved polyethylene resin and complies with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2. Its natural translucent color enables quick visual checks of the water level without the need for external sensors or gauges.
