The Snyder Industries 65 Gallon Horizontal Leg Tank (SKU SII-1031500C26) is a low, wide haul tank that sits stable on a trailer or skid and rides out the slosh of transport. It measures 37 inches long by 32 inches wide by 20 inches tall, so the footprint is a compact 32.0 x 37.0 inches and the center of gravity stays low. The tank is molded from High Density Linear Polyethylene in white, with a specific gravity rating of 1.9 - meaning it is engineered to carry contents up to 1.9 times the density of water, which is why this horizontal leg tank handles the dense agricultural and chemical loads that a standard 1.0 SG water tank would not.
Does it work for your load?
Plan around weight, not just gallons. Filled with plain water this 65-gallon tank carries about 542 pounds; loaded to its full 1.9 SG rating it is rated for contents up to 1030 pounds. That 1030 lb / 1.9 SG ceiling is your buying gate - anything denser or heavier than that is out of scope for this SKU. The molded legs and broad base spread that weight across your trailer deck or transport frame instead of concentrating it, which is the whole point of a horizontal leg tank. Use the Tank Sizing Calculator to convert your specific product's density into a real fill weight before you load, and the Tank Sizing Guide if you are deciding between sizes. Confirm the fitting size and location on the unit you receive against your plumbing before you build the mount.
Chemical compatibility
This tank is HDLPE with a 1.9 specific-gravity rating, which makes it a true chemical-haul tank rather than a water-only vessel. The chemicals below are drawn from the OEM chemical-resistance chart, which is concentration- and temperature-specific - always match your actual concentration and operating temperature to the chart, and pair the tank with the listed fitting and gasket materials. A common diesel-fleet use is DEF (diesel exhaust fluid) at 32.5%, which calls for 316SS fittings and EPDM gaskets:
- DEF (32.5%) - 316SS fittings, EPDM gaskets
- Acetic Acid (60%) - PP/PVC fittings, EPDM gaskets
- Aluminum Sulfate (50%) - PVC fittings, EPDM gaskets
- Calcium Chloride (40%) - PVC fittings, EPDM gaskets
- Ferric Chloride (50%) - PVC fittings, EPDM gaskets
- Ferric Sulfate (60%) - PVC fittings, EPDM gaskets
- Ferrous Sulfate (20%) - PVC fittings, EPDM gaskets
- Hydrochloric Acid (37%) - PVC fittings, Viton gaskets
- Hydrofluoric Acid (48%) - PP/PVC fittings, Viton gaskets
- Hydrofluosilicic Acid (26%) - PP/PVC fittings, Viton gaskets
- Hydrogen Peroxide (50%) - PVC fittings, Viton gaskets
- Magnesium Chloride (30%) - PVC fittings, EPDM gaskets
- Peracetic Acid (30%) - 316SS fittings, Aflas gaskets
- Phosphoric Acid (85%) - PVC fittings, Viton gaskets
- Polyaluminum Chloride - PVC fittings, EPDM gaskets
- Potassium Carbonate (50%) - PVC fittings, EPDM gaskets
- Potassium Hydroxide (saturated) - PVC fittings, EPDM gaskets
- Sodium Bisulfate - PVC/PP fittings, EPDM gaskets
- Sodium Bisulfite - PVC/PP fittings, EPDM gaskets
- Sodium Carbonate (30%) - PVC fittings, EPDM gaskets
- Sodium Hypochlorite (<16.5%) - PVC fittings, Viton gaskets
- Sodium Thiosulfate (40%) - PVC fittings, EPDM gaskets
- Sulfuric Acid (98%) - CPVC fittings, Viton gaskets
- Urea Solution (50%) - PP/PVC fittings, EPDM gaskets
- Ethylene Glycol (100%) - PVC fittings, EPDM gaskets
- Propylene Glycol - PP/316SS fittings, EPDM gaskets
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
See the full chemical compatibility reference, and remember the gasket call matters as much as the resin - EPDM and Viton are not interchangeable for the aggressive acids above.
The mistake to avoid
The costly error on a leg tank like this is matching the wrong gasket to the chemical. The 1.9 SG HDLPE shell can hold these products, but a chlorine or strong-acid load on an EPDM gasket will fail at the fitting long before the tank does - Sodium Hypochlorite, Hydrochloric Acid, Phosphoric Acid, and Sulfuric Acid all call for Viton, while DEF and Peracetic Acid need 316SS hardware. Confirm your exact concentration and operating temperature against the OEM chart, because compatibility shifts with both.
