The Norwesco 50 Gallon Portable Loaf Utility Tank is a compact white polyethylene loaf tank built for fleet sprayers, spot-spray rigs, and mobile water hauling where a low, wide footprint matters more than vertical capacity. It measures 23" high by 19" wide by 38" long, so it rides low and stable on a truck bed, trailer, or skid. Filled with water at 50 gallons it carries roughly 417 pounds of contents, so mount and strap it for that loaded weight before you fill.
Will it work for your job?
This is a one-fill, low-profile loaf tank designed to nest into the bed of a utility truck or onto a small trailer. The 38" length and 19" width give you a 19.0 x 38.0 footprint that drops the center of gravity for safer transport than a tall vertical of the same volume. The tank carries a 1.5 specific gravity rating, which means the polyethylene wall is built to hold contents up to 1.5 times the weight of water - up to a maximum rated contents weight of 626 pounds. That is real headroom you are paying for: water is SG 1.0 (about 417 pounds at 50 gallons), and the wall is structurally rated to handle denser agricultural and utility liquids, such as many fertilizer or solution blends, up to that 1.5 SG / 626-pound ceiling. The 1.5 rating is a structural-capacity figure only - it is not a chemical-suitability claim, so confirm compatibility with Norwesco before storing anything other than water.
The 8-inch lid and fill port
The top of this loaf tank carries a double-lead-thread opening sized for an 8-inch lid (see the technical drawing on this page for the fill-port detail). The tank ships with that opening, but the 8-inch double-lead-thread lid is the mating part you must confirm or order to close the fill port, and any vented cap or fill plumbing has to match that same thread. Because the threaded lid is the only port on the tank, the cap seal is your single leak path - many failures on portable spray rigs happen at the gasket, not the tank body - so the lid gasket or O-ring must be chemically compatible with whatever you store, not just the polyethylene wall.
Sizing, mounting, and the mistake to avoid
Plan your mount around the loaded weight, not the empty shell, and use the full-versus-rated delta as your tie-down range: 417 pounds at 50 gallons of water up to 626 pounds at the tank's rated contents maximum. The most common error on a loaf tank this size is strapping for the empty weight - a bare shell is light and easy to handle, but a full one sloshes hundreds of pounds on every turn and stop. Secure it across the 38-inch length with rated tie-downs to a deck or skid. Use the Tank Sizing Calculator to match this 50 gallon capacity to your refill cycle and route length, and read the Tank Sizing Guide if you are deciding between a loaf tank and an upright. For farm-fleet road use, the guide to Norwesco loaf-style portable utility tanks and the 49 CFR 173.5 agricultural exemption is a pre-purchase compliance check - confirm your use qualifies before relying on that exemption. If the tank lives in one spot, the concrete pad sizing guide for above-ground polyethylene tanks covers a stable base.
