The Snyder Industries 125 Gallon Plastic Horizontal Leg Tank (SKU SII-1003600C26) is a white polyethylene horizontal leg tank built for hauling liquid on a trailer or skid. Its integrally molded legs let the full 125-gallon body sit low and stable while you move, and the 1.9 specific gravity rating is the number that should drive your buying decision: this tank is engineered to carry liquids substantially heavier than water, which is what separates a working horizontal leg tank from a simple water carrier. At a 1.9 specific gravity rating this is already the heaviest-content tier for this body, so there is no higher-SG version to step up to.
Will it work for your load?
The tank measures 44 inches long, 32 inches wide, and 35 inches high, with a 32.0 x 44.0 inch footprint to plan your trailer or skid mounting around. Filled with plain water it carries roughly 1,042 pounds; at its full 1.9 specific gravity rating the rated contents weigh up to 1,981 pounds, so size your trailer axles, tie-downs, and frame to the heavier figure if you are hauling a dense liquid. Confirm your liquid's specific gravity against that 1.9 ceiling before you load, and use the Tank Sizing Calculator and Tank Sizing Guide if you are still deciding between capacities. Factory fitting and outlet configuration is not published in our spec data for this SKU, so confirm port count, size, and placement with us or against the technical drawing on this page before you plumb it. If this tank is part of an agricultural or applicator fleet, our guide on applicator and leg tanks for fertilizer walks through DOT non-roadable trailer scope, and the portable utility tank classification guide covers the 49 CFR 173.5 agricultural exemption.
Chemical compatibility
Resin is listed as HDLPE but unconfirmed, so confirm HDLPE versus XLPE construction with us before putting this tank into chemical service. The 1.9 specific gravity rating is what allows it to hold heavier chemicals at the densities below. Compatibility is concentration- and temperature-specific; always check the OEM chemical-resistance chart for your exact concentration and operating temperature before committing a tank to a chemical. With the right fitting and gasket materials this tank can be specified for chemicals including acetic acid (60%) with PP or PVC fittings and EPDM gaskets, aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%) with 316SS fittings and EPDM gaskets, ethylene glycol (100%), ferric chloride (50%), ferric sulfate (60%), ferrous sulfate (20%), magnesium chloride (30%), potassium carbonate (50%), potassium hydroxide (saturated), propylene glycol with PP or 316SS fittings, sodium bisulfate, sodium bisulfite, sodium carbonate (30%), sodium thiosulfate (40%), urea solution (50%) with PP or PVC fittings, polyaluminum chloride, and zinc orthophosphate with PP or 316SS fittings. More aggressive services call for Viton or Aflas gaskets and specific fitting metallurgy: hydrochloric acid (37%), hydrofluoric acid (48%), hydrofluosilicic acid (26%), hydrogen peroxide (50%), peracetic acid (30%) with 316SS fittings and Aflas gaskets, phosphoric acid (85%), sodium hypochlorite (under 16.5%), sulfuric acid (98%) with CPVC fittings and Viton gaskets, and ozonated water up to 10 PPM with PVC fittings and EPDM gaskets. See each linked page and the full chemical compatibility reference for the OEM chart detail.
The mistake to avoid
The most common error on a horizontal leg tank like this is matching the fitting and gasket material to the tank instead of to the liquid. The polyethylene shell may handle a chemical fine while a standard EPDM gasket fails on an oxidizer or strong acid; note how hydrochloric, phosphoric, and sulfuric acid, hydrogen peroxide, and sodium hypochlorite all move to Viton, and peracetic acid to Aflas, in the listing above. Spec the gasket and fitting metallurgy to the chemical and concentration, not to the tank body. The second mistake is loading by volume instead of weight: a tank that handles 125 gallons of water can be overloaded well before it is full when the liquid approaches the 1.9 specific gravity ceiling.
