The Snyder Industries 525 Gallon Plastic Horizontal Leg Tank in White is a haul-ready polyethylene tank built for fertilizer, water, and chemical transport on a nurse trailer or skid. It measures 53 inches tall, 48 inches wide, and 68 inches long. Filled with water it carries roughly 4,378 pounds; at its 1.5 specific gravity rating it is engineered to hold up to about 6,568 pounds of contents, so heavier-than-water solutions like liquid fertilizer blends stay within the tank's structural envelope.
Will this horizontal leg tank work for your job?
This is a Snyder horizontal leg tank rated to 1.5 specific gravity, which is the number that decides what you can safely haul. Water weighs about 8.34 pounds per gallon (SG 1.0), so a full 525 gallons of water sits near 4,378 pounds. The 1.5 rating gives you headroom for denser liquids, but the governing limit is the 6,568 pound contents rating: for any product heavier than water you fill to weight, not to volume, and stop at that ceiling rather than topping off the tank. With a 48 x 68 inch footprint, plan your trailer or skid deck around the tank and confirm tie-down points. To match this 525 gallon size to your route, batch, and refill cadence, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit. See the technical drawing on this page for the molded fitting and outlet locations.
Chemical compatibility
This tank is molded in polyethylene with a 1.5 specific gravity rating. The resin is recorded as HDLPE in our data but ends with a question mark, so confirm whether your unit is HDLPE (high-density linear) or XLPE (cross-linked) before placing it in chemical service, since the two resins handle aggressive chemistries differently. Within the 1.5 SG rating, this tank is suited to the following at the concentrations shown, paired with the correct fitting and gasket materials per the OEM chemical-resistance chart, which is concentration- and temperature-specific:
- Acetic Acid 60% - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate 50% - PVC fittings, EPDM gaskets
- Calcium Chloride 40% - PVC fittings, EPDM gaskets
- DEF 32.5% - 316 stainless fittings, EPDM gaskets
- Ferrous Sulfate 20% - PVC fittings, EPDM gaskets
- Magnesium Chloride 30% - PVC fittings, EPDM gaskets
- Sodium Carbonate 30% - PVC fittings, EPDM gaskets
- Urea Solution 50% - PP/PVC fittings, EPDM gaskets
- Ozonated Water up to 10 PPM - PVC fittings, EPDM gaskets
The DEF (diesel exhaust fluid) and urea solution compatibility makes this a practical mobile tank for ag and fleet refueling work, but note that DEF requires 316 stainless fittings with EPDM gaskets, not the PVC most ag tanks ship with, to avoid contaminating the fluid and tripping downstream SCR sensors. Several common chemistries need a heavier-walled 1.9 specific gravity tank rather than this 1.5 SG unit: Ethylene Glycol, Ferric Chloride, Ferric Sulfate, Hydrochloric Acid, Hydrofluoric Acid, Hydrofluosilicic Acid, Hydrogen Peroxide, Peracetic Acid, Phosphoric Acid, Polyaluminum Chloride, Potassium Carbonate, Potassium Hydroxide, Propylene Glycol, Sodium Bisulfate, Sodium Bisulfite, Sodium Hypochlorite, Sodium Thiosulfate, Sulfuric Acid, and Zinc Orthophosphate. If your product is on that list, do not under-spec the tank; for the SPCC-relevant aggressive chemistries that also call for secondary containment, our guide to Snyder Captor double-wall tanks for SPCC 40 CFR 112 is the natural next step. Always verify your exact chemical, concentration, and temperature against the OEM chart and our chemical compatibility resource.
The mistake to avoid
The single costliest error on a haul tank is ignoring the specific gravity number. This tank is rated to 1.5 SG; pouring a 1.9 SG product into it, or running it full with a dense load past its 6,568 pound contents rating, overstresses the wall. Match the SG, match the gasket and fitting material to the chemical (EPDM, Viton, or 316 stainless as the chart specifies), and confirm the resin type before chemical service.
