44 Gallon Custom Roto-Mold Marine Water Tank (MPN: MW-48)

Description

The Custom Roto-Mold 44 Gallon Marine Water Tank (Part# MW-48) is engineered to meet the demands of potable water storage in marine, RV, and mobile vehicle systems. Its flat, low-profile footprint makes it ideal for use in tight vertical clearance spaces, such as under decks, in floor compartments, or beneath seating.

This tank is built using rotationally molded polyethylene resin, producing a seamless, one-piece construction that ensures superior resistance to cracks, ruptures, and structural fatigue. The use of FDA-approved materials means the tank complies with FDA Regulation 21 CFR 177.1520 (1) 3.1 and 3.2, making it safe for potable water use.

The MW-48 ships blank (no fittings) to allow full flexibility in designing a custom plumbing layout for your system. With rugged construction and space-efficient dimensions, it's a practical solution for mid-size freshwater storage applications on the move.
