50 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-533)

Description

The Custom Roto-Mold 50 Gallon Marine Water Tank (Part# MW-533) is a vertically oriented potable water storage tank designed for space-conscious marine and mobile installations. Its tall profile offers generous capacity while minimizing footprint, making it ideal for tight deck corners, under benches, or storage compartments in boats, trailers, and RVs.

This tank is constructed using rotational molding technology, creating a seamless, one-piece body that resists cracks, deformation, and structural failure. Built to withstand the vibration, movement, and moisture typical of mobile and marine environments, the MW-533 provides long-term reliability even under harsh conditions.

Manufactured from FDA-approved polyethylene resin, the tank complies with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, ensuring that stored water is safe for drinking and cooking use. The tank is shipped blank, giving you the flexibility to add fittings in custom locations to suit your specific system layout.
