Description
The Custom Roto-Mold 50 Gallon Marine Water Tank (Part# MW-480) is built to provide safe and efficient potable water storage for marine, RV, and mobile vehicle applications. Its compact, upright design makes it ideal for installations in tight, vertically-oriented spaces such as equipment bays, storage lockers, or utility compartments.
Constructed using rotational molding technology, this tank features a seamless, one-piece build that offers excellent resistance to cracks, chips, and structural failure. The use of FDA-approved polyethylene resin ensures compliance with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it suitable for storing fresh, potable water.
