The Snyder Industries 750 Gallon Horizontal Leg Tank (SKU SII-1300000C26) is a 1.9 specific-gravity polyethylene vessel built to haul heavy liquids on a trailer or skid. It holds 750 gallons, measures 117 inches long by 46 inches wide by 48 inches high, and rides on molded legs with the securing hoops named in the title that strap the tank down for transport. The 1.9 SG rating is the number that matters here: the tank wall is engineered to carry contents up to 1.9 times the weight of water, which is why this horizontal leg tank shows up so often for fertilizer and chemical hauling rather than plain water transport.
Will it work for your load?
Full of water, this tank carries about 6,255 pounds. At its 1.9 SG rating, the maximum rated contents weight climbs to 11,884 pounds, so your trailer, frame, and tie-downs need to be sized for that figure when you run dense liquids like liquid fertilizer blends. Those securing hoops are the load path that restrains the tank at that 11,884 lb max, not the 6,255 lb water figure, so verify your hoop and strap rating against the heavy number. The 46 x 117 inch footprint is what you design your trailer deck or saddle around. Use the Tank Sizing Calculator to confirm the loaded weight against your trailer rating, and the Tank Sizing Guide if you are matching this horizontal leg tank to a haul volume. Because this is a portable utility tank, review how DOT classifies farm-fleet transport in our guide on portable utility tanks and the 49 CFR 173.5 agricultural exemption, and the applicator and leg tank scope for fertilizer hauling. For blend work, our write-up on fertilizer-blend tank stratification covers the layering and salting-out problems that catch a stratified tank before the spreader runs off-spec.
Chemical compatibility
This Snyder tank is polyethylene rated to 1.9 specific gravity. The resin type is not yet confirmed against this exact model, so confirm whether it is HDLPE or XLPE with us before putting it into chemical service. That confirmation is not boilerplate: it specifically gates the strong oxidizers on the list below, where crosslinked and linear polyethylene do not behave the same way. The fitting and gasket materials shown for each chemical are the materials required to run that chemical, not a description of what ships installed on the tank. The fitting and outlet configuration is not specified in this listing, so confirm the as-shipped fittings by phone before you order. The following chemicals are compatible with a 1.9 SG polyethylene tank at the concentrations and materials shown, per the OEM chemical-resistance chart, which is always concentration- and temperature-specific: Acetic Acid at 60% (PP/PVC fittings, EPDM gaskets), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (note the 316SS fitting requirement, which stands out against the otherwise PVC list and EPDM gaskets), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC fittings, Viton gaskets), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Hypochlorite below 16.5%, a hard concentration ceiling and not a guideline (PVC, Viton), Sodium Thiosulfate at 40% (PVC, EPDM), Sulfuric Acid at 98% (CPVC, Viton), Urea Solution at 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Match your fitting and gasket material to the chemical you are running, and see the full chemical compatibility reference before committing to a service.
The mistake to avoid
The most common error on a tank like this is loading a dense chemical and using the wrong gasket. A 1.9 SG rating tells you the polyethylene shell can carry the weight, but the fitting and gasket materials above are what survive the chemistry, and they differ chemical by chemical: EPDM for the salts and glycols, but Viton for hydrochloric, hydrofluoric, phosphoric, sulfuric, hydrogen peroxide, and sodium hypochlorite, and Aflas for peracetic acid. Pairing an EPDM gasket with a strong oxidizer is how outlets fail in the field. Confirm the resin type, then match every fitting and gasket to the chemical, not just to the tank.
