A 500 gallon black loaf tank for a flatbed, a trailer or a low spot under a roof
The Norwesco 500 gallon black loaf tank, part number 43843B, is a low, flat polyethylene utility tank 92 inches long, 48 inches wide and 31 inches tall, weighing 186 lb empty. The loaf shape keeps the load low and the top flat, so it rides on a flatbed or a trailer deck without a cradle and fits under a bench, a mezzanine or a low barn eave where a vertical tank will not. Full of water it carries 4170 lb, so the trailer or truck rating, not the tank, is usually the limit. The tank is rated for liquids up to 1.5 specific gravity: water, most liquid fertilizers and many common chemicals. The top opening is an 8 inch threaded vented lid; no outlet fitting is listed, so order a bulkhead fitting with it or tell us where the drain goes. The resin is FDA compliant per Norwesco, Norwesco lists its water tanks under NSF/ANSI 61 (the listing names no models), the service limit is 120 F, and the warranty is 3 years. Black blocks light, which keeps algae out of water that sits between uses.

Water hauling, nurse tank duty and low-clearance storage
Five hundred gallons on a 92 by 48 inch footprint is the nurse tank size for a sprayer, the water supply for a dust control or concrete crew, or the day's stock water for a remote pasture. On a vehicle, strap it through the moulded recesses, never over the lid, and keep the straps tight; a loaf tank that walks on the deck is the one that cracks. Our write-up on loaf style utility tanks covers how these tanks are classified on the road and the agricultural exemption most farm use falls under. On the ground, the 31 inch height is what sells it: it slides under a low roof or a bench as emergency water, a fire reserve or a reuse tank. The remote-site reservoir piece covers fire reserve sizing, the reuse topology piece covers where a tank like this sits in a reuse train, and the pad sizing framework covers the flat, continuous surface it needs under the whole base. Confirm the volume with the sizing calculator and the sizing guide.
What to check before you buy
- The outlet. None is listed with the tank. Tell us the size and the end you want it in and we fit a bulkhead fitting before it ships, or send it loose if you would rather place it yourself.
- The lid. An 8 inch threaded vented lid: fill hose, suction line and float all go through it. The vent must stay open or the pump will pull the tank walls in.
- The liquid. Polyethylene handles water, most fertilizers and many common chemicals. Tell us what goes in and we check it against the material before the order ships.
- The deck. 92 by 48 inches of flat, continuous support under the whole base. A loaf tank bridging two cross members carries the load in the wrong places.
- The drawing. Norwesco's drawing for 43843B, linked under Technical Drawing on this page, gives the exact footprint and the flat areas where a fitting can go.
