50 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-330)

Description

The Custom Roto-Mold 50 Gallon Marine Water Tank (Part# MW-330) is built for dependable potable water storage in marine and mobile environments. Its low-profile, rectangular shape makes it an excellent choice for installations where vertical clearance is limited, such as floor spaces or under seating areas in boats, RVs, and trailers.

Constructed using rotational molding technology, this tank features a seamless, one-piece body that ensures superior resistance to cracking, impact, and leaks. It’s designed to handle the rigors of vibration-heavy marine and mobile conditions without failure.

Made from FDA-approved polyethylene resin, the MW-330 complies with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, ensuring safe and hygienic storage of drinking water. The tank ships blank, giving you the flexibility to install fittings exactly where needed for your system layout.
