58 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-486)

Description

The Custom Roto-Mold 58 Gallon Marine Water Tank (Part# MW-486) is engineered for potable water storage in marine, RV, and mobile applications requiring a low-profile footprint and moderate capacity. Its 7.5" height makes it ideal for installations where vertical clearance is limited, such as under-floor compartments, deck spaces, or shallow utility bays.

Manufactured using rotational molding technology, the MW-486 offers a seamless, one-piece polyethylene design that provides outstanding resistance to cracks, ruptures, and vibration-related stress. This construction ensures long-term durability in high-motion or off-road environments.

Made from FDA-approved polyethylene resin, the tank complies with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, guaranteeing safe storage of drinking water. The tank ships blank (with no fittings installed), giving installers complete freedom to configure plumbing as needed.
