The Snyder Industries 1025 Gallon Horizontal Leg Tank (SII-32046) is a 139-inch-long white tank built for transport and chemical haul work where the body rides supported along its full length. Molded from high-density linear polyethylene with a 1.9 specific gravity rating, this horizontal leg tank carries heavy contents that would overload a standard water-grade vessel. The 1.9 rating is the headline number: it means the wall is engineered to hold liquids up to 1.9 times the weight of water, which is why this tank suits chemical and fertilizer service rather than water hauling alone.
Will it work for your application
This tank holds 1025 gallons and measures 55 inches high, 48 inches wide, and 139 inches long, with a 48.0 x 139.0-inch footprint. Filled with water it weighs about 8,548 pounds; at its full 1.9 specific gravity rating it can carry up to 16,242 pounds of contents. Use those weights when you spec the trailer, skid, or applicator frame underneath it - the leg-tank geometry is designed to be cradled and strapped along its length, so the support structure has to carry that loaded figure across the full footprint. If you are still confirming the size against your route or batch volume, the Tank Sizing Calculator and Tank Sizing Guide walk through capacity and weight planning. See the technical drawing on this page for fitting locations and exact dimensions before you build the cradle.
Chemical compatibility
This is an HDLPE tank with a 1.9 specific gravity rating, suited to dense chemical service. The chemicals below are compatible per the OEM chemical-resistance chart, but that chart is concentration- and temperature-specific, so confirm your exact concentration and operating temperature before service. Match the fitting and gasket materials to the chemical - the chart calls for these:
- 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%) - 316SS fittings, EPDM gaskets
- Ethylene Glycol (100%) - 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
- Propylene Glycol - PP/316SS 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
- Zinc Orthophosphate - PP/316SS fittings, EPDM gaskets
- Ozonated Water (up to 10 PPM) - PVC fittings, EPDM gaskets
For a fast gasket BOM: 7 of these services require Viton (hydrochloric, hydrofluoric, hydrofluosilicic, phosphoric, and sulfuric acids, hydrogen peroxide, and sodium hypochlorite), peracetic acid alone requires Aflas, and the rest run EPDM. The fitting body matters too - sulfuric acid at 98% is the only service here needing CPVC rather than PVC, and four services call for stainless instead of plastic fittings: DEF (32.5%) and peracetic acid (30%) need 316SS, while propylene glycol and zinc orthophosphate need PP/316SS. The mistake to avoid is defaulting to EPDM and PVC across the board; pairing the wrong elastomer or fitting body with the chemical is what fails first, not the polyethylene wall. For the full picture across all chemicals, see our chemical compatibility reference. A single-wall 1.9-SG tank hauling acids like hydrochloric, sulfuric, and ferric chloride is exactly the case that triggers secondary-containment planning - the Snyder Captor double-wall SPCC walkthrough covers the 40 CFR 112 path if your site needs it.
Hauling and fertilizer use
Because this is a leg tank, it is a common choice for fertilizer blend transport and applicator setups where the tank is mounted to a trailer or truck bed. If you are blending fertilizer, read our guide on fertilizer-blend tank stratification so the mix does not salt out or layer before it reaches the spreader. For the DOT side of running these tanks on the road, the applicator and leg-tank scope explainer and the portable utility tank classification guide cover the agricultural exemption and roadability questions.
This 1025-gallon horizontal leg tank ships LTL freight, quoted live to your ZIP. It molds at two Snyder Industries plants - Albertville, AL and Merced, CA - so an order routes from whichever origin is closer to you, which directly trims the LTL bill on a 139-inch tank weighing roughly 8,548 pounds full of water and rated to 16,242 pounds loaded, where freight is the real cost.
