81 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-281)

Description

The Custom Roto-Mold 81 Gallon Marine Water Tank (Part# MW-281) is purpose-built for potable water storage in mobile and marine applications. With a low-profile, rectangular footprint, this tank is ideal for installations where space to space fitting is critical—such as beneath decks, inside benches, or along structural voids in boats and RVs.

Molded using advanced rotational technology, this one-piece tank delivers seamless strength and excellent resistance to cracking, leaks, and deformation. It’s engineered to handle the rigors of marine environments, including vibration, motion, and saltwater exposure.

Manufactured from FDA-approved polyethylene resin, the tank meets FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it safe for drinking water use. The tank ships blank, allowing custom fitting placement to suit your project.
