The Enduraplas 150 Gallon Yellow Horizontal Leg Tank (SKU THF00150Y) is a low-slung polyethylene haul tank built to ride on an applicator skid, truck bed, or non-roadable trailer and carry heavier-than-water chemistry. It holds 150 gallons in a footprint of 41.0 x 46.0 inches and stands 28 inches tall, so it loads under low clearance and keeps its center of gravity down when full. Carried as a horizontal leg tank in yellow with a 1.9 specific gravity rating, it is the kind of horizontal tank field crews reach for when 150 gallons of dense product has to travel and stay put.
Will it handle your load
The number that matters on a haul tank is not the gallons, it is the weight that rides over your axles. Filled with water this tank carries about 1,251 lb of contents. At its full 1.9 specific gravity rating it is built to carry up to 2,377 lb of product, which is what lets it run dense fertilizer blends and concentrated chemistry that a 1.0 or 1.5 SG-rated tank is not built to carry. Plan your trailer, skid, and tie-downs around that loaded figure, not the dry weight. Use the Tank Sizing Calculator and the Tank Sizing Guide to match the weight to your equipment, and check the technical drawing on this page for the leg layout and outlet position before you build your mount.
Chemical compatibility
This tank is rated to 1.9 specific gravity in polyethylene. The resin shown in our data ends in a question mark (HDLPE?), so confirm whether your tank is high-density linear (HDLPE) or cross-linked (XLPE) polyethylene before putting it into chemical service, since the two resins resist different chemistries. This tank ships without fittings: bulkhead fittings, valves, and gaskets are selected and ordered separately to match your chemical, so confirm outlet size and thread against the technical drawing on this page. Every pairing below should be checked against the OEM chemical-resistance chart for your exact concentration and temperature.
Match the fitting and gasket material to your chemical, not just the tank, because the wrong gasket fails long before the polyethylene does. Most pairings below use EPDM gaskets; the strong acids and oxidizers (hydrochloric, hydrofluoric, hydrofluosilicic, hydrogen peroxide, phosphoric, sodium hypochlorite, sulfuric) require Viton, and peracetic acid requires Aflas. Watch the metal-fitting exceptions too: DEF and peracetic acid call for 316 stainless fittings, and sulfuric acid calls for CPVC rather than standard PVC. Common products this tank pairs with:
- 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 (reference chart pending)
See the full chemical compatibility reference, and pick concentration and temperature carefully against the OEM chart.
The mistake to avoid
The single most common error on a 1.9 SG tank is treating it like a water tank. Filling 150 gallons of dense product without recalculating the loaded weight at the right specific gravity is how trailers get overloaded and chemistry gets dumped on the road. Confirm your product's specific gravity is at or below 1.9; if it exceeds 1.9, this is not the tank, so call 866-418-1777 before you order. Build your mount and tie-downs for the loaded figure, and if you are hauling fertilizer blends read up on tank stratification and mixing, plus the applicator and leg tank DOT/NRT scope and 49 CFR 173.5 agricultural exemption before you run on public roads.
