Norwesco 150 Gallon Plastic Applicator Saddle Tank in White

The Norwesco 150 Gallon Applicator Saddle Tank (SKU N-40648) is a white polyethylene saddle tank built to ride along a frame or trailer and carry liquid product to the field.It holds 150 gallons, weighs about 50 lb empty, and measures roughly 58" long by 30" wide by 33" high.It carries an 8" lid and a 1.25" outlet, is FDA approved, and is rated to a 1.5 specific gravity so it can haul liquids heavier than water.This is the tank people search for as a "150 gallon norwesco applicator saddle" for fertilizer and utility hauling.

Will it handle your load?

The 1.5 SG rating is the number that matters here.Filled with plain water, 150 gallons weighs about 1,251 lb; loaded to the full 1.5 SG rating, the contents can reach roughly 1,876 lb.Confirm your product's density falls at or under 1.5 SG before you fill, and secure the saddle against that weight shifting in transit.Keep contents at or below the 120 F / 48 C maximum service temperature.The 1.25" outlet is a molded port and the 8" lid is a molded opening — confirm the bulkhead fitting and gasket you plumb into it separately, matched to your liquid.If you are sizing a fleet or matching contents weight to a trailer rating, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide.For how these tanks sit within farm-fleet DOT scope, see our guides on Norwesco applicator and leg tanks for fertilizer and the 49 CFR 173.5 agricultural exemption.

Chemical compatibility

This tank is polyethylene with a 1.5 SG rating; the resin is listed as HDLPE but marked unconfirmed.For water, DEF, and fertilizer hauling the resin question is moot, but for any acid or oxidizer below, confirm HDLPE versus XLPE with us first, because cross-link versus high-density changes chemical service life.Compatibility below is drawn from the Snyder Industries OEM chemical-resistance chart and is concentration- and temperature-specific, so verify your exact chemical, concentration, temperature, and fitting and gasket materials before you commit.At the 1.5 SG rating this tank suits acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), DEF (32.5%), ferrous sulfate (20%), magnesium chloride (30%), sodium carbonate (30%), urea solution (50%), and ozonated water (up to 10 PPM), typically with PVC or PP fittings and EPDM gaskets.DEF is the exception — spec 316SS wetted metal, not PVC or PP.Fertilizer blends can stratify in a saddle tank, so review our blend-tank stratification guide before running to the spreader.Heavier chemistries — ethylene glycol, ferric chloride, hydrochloric acid, hydrogen peroxide, phosphoric acid, sodium hypochlorite, and sulfuric acid among them — require a higher 1.5 SG tank, not this one.Note that jump changes both the tank rating and the hardware: several of those need Viton gaskets, and sulfuric acid calls CPVC fittings, so your existing EPDM/PVC plumbing does not carry over.Call us and we will point you to the right unit.Always confirm against the OEM chart and our chemical compatibility reference.

The mistake to avoid

Do not put a 1.9-SG chemical in a 1.5-SG tank.The tanks look identical, but the wall is not built for the heavier load, and overfilling past the SG rating is the fastest way to fatigue a saddle tank.Match the density, match the fittings and gasket to your chemical, and confirm the resin before you fill.
