47 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-537)

Description

The Custom Roto-Mold 47 Gallon Marine Water Tank (Part# MW-537) is built for space-limited installations that require low-profile, high-capacity potable water storage. With a height of only 6 inches and a generous 60" x 34" footprint, it’s ideal for underfloor, deck-mounted, or shallow compartment applications in boats, RVs, and mobile trailers.

Constructed using advanced rotational molding technology, the tank features a seamless, one-piece body that resists cracking, stress damage, and deformation. It performs reliably in mobile environments where vibration and shifting loads are common.

This tank is manufactured using FDA-approved polyethylene resin and meets FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, ensuring its safety for potable water applications. It ships blank, so you can add fittings as needed to suit your specific installation layout.
