Description

The Custom Roto-Mold 42 Gallon Marine Water Tank (Part# MW-405) is designed for potable water storage in marine, RV, and mobile environments. It features a broad, low-profile footprint, ideal for shallow compartments, deck storage, or under-bench installations. Constructed using rotational molding technology, it results in a seamless, one-piece body that resists cracks, leaks, and structural fatigue. It is manufactured from FDA-approved polyethylene resin, ensuring compliance with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it safe for drinking water use. The tank ships blank (no pre-installed fittings), allowing full flexibility for plumbing configuration. It is rugged, reliable, and engineered to withstand vibration, UV exposure, and saltwater conditions.
