23 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-528)

Description

The Custom Roto-Mold 23 Gallon Marine Water Tank (Part# MW-528) is a low-profile, ultra-slim solution designed for potable water storage in marine and mobile applications where vertical space is limited. Its extra-flat layout makes it ideal for mounting beneath floors, decks, bunks, or in shallow storage compartments on boats, RVs, trailers, or off-grid mobile units.

Constructed using rotational molding technology, this tank features a seamless, one-piece body that provides excellent durability and resistance to cracking, warping, and structural fatigue. It maintains its shape and strength even under motion and vibration, making it ideal for marine environments.

Made from FDA-approved polyethylene resin, the MW-528 meets the safety requirements of FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, ensuring clean, safe potable water storage. This tank ships blank with no fittings installed, giving installers full freedom to place inlets, outlets, and vents according to their layout and application needs.
