45 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-483)

Description

The Custom Roto-Mold 45 Gallon Marine Water Tank (Part# MW-483) is engineered to meet the requirements of mobile potable water storage in marine, RV, and trailer installations where horizontal footprint is available but vertical clearance is extremely limited. With its ultra-low 5.5" height, this tank is ideal for under-deck, floor-mounted, or shallow compartment setups.

Manufactured using rotational molding technology, the MW-483 features a seamless, one-piece construction that resists cracks, chips, and deformation, ensuring long-term performance even under constant motion, vibration, and environmental stress.

Constructed from FDA-approved polyethylene resin, this tank complies with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, providing safe storage of potable water. It ships blank (without pre-installed fittings) to allow for full customization during installation.
