Norwesco 150 Gallon Saddle Applicator Tank in Black with fittings

The Norwesco 150 Gallon Saddle Applicator Tank (SKU N-45673) is a black polyethylene specialty tank built for agricultural applicator and fertilizer-blend duty.It holds 150 gallons, weighs 50 lb empty, and carries a 1.5 specific gravity rating with an FDA Approved resin and a 120 F / 48 C maximum service temperature.The saddle profile measures 58" long by 30" wide by 33" high, with a 30.0 x 58.0 in footprint that seats it on a trailer or skid.It arrives with fittings: a 1.25" outlet at the low point and an 8" lid for filling and inspection.

Will it handle your load?

Sizing comes down to the weight of what you pour in, not just the gallon number.Full of water this 150 gallon tank runs about 1,251 lb; loaded to its 1.5 SG rating it can carry up to 1,876 lb of contents.Confirm your applicator frame, saddle mounts, and trailer axle are rated for the loaded figure for the fluid you actually haul.Run your fluid and gallon target through the Tank Sizing Calculator, and use the Tank Sizing Guide if you are matching this Norwesco saddle tank to a spreader or nurse setup.Because this is a mobile applicator tank rather than a roadable trailer, review the Norwesco Applicator and Leg Tanks for Fertilizer: DOT Non-Roadable Trailer (NRT) Scope and the 49 CFR 173.5 agricultural exemption writeup to place it correctly under DOT rules for farm fleet use.

Chemical compatibility

This is a polyethylene tank (resin listed as HDLPE?) with a 1.5 specific gravity rating, referenced against the Snyder Industries OEM chemical resistance chart.Because the resin code ends in a question mark, confirm HDLPE versus XLPE with us before you commit it to chemical service.Compatibility is concentration- and temperature-specific, and this tank has a hard 120 F / 48 C ceiling, so verify your exact chemical, concentration, service temperature, and fitting plus gasket material against the OEM chart before ordering — warm or exothermic fluids are exactly where a tank derates.

At its 1.5 SG rating this tank suits, among others: 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).DEF and urea are rated at SG 1.35 and sit comfortably under this tank's 1.5 rating, and the FDA Approved resin fits DEF-grade duty — a natural pairing for the applicator and fertilizer work this saddle tank is built for.Most of these fluids call for PVC or PP fittings with EPDM gaskets, but DEF is the exception: spec 316SS wetted metal with EPDM, not PVC.Match fitting and gasket material to the fluid, not just the tank wall.

Some fluids need a higher-SG tank than this 1.5 unit and should not go in it, and their wetted materials vary more than the base list: Sulfuric Acid (98%) needs CPVC with a Viton gasket, Peracetic Acid (30%) needs 316SS with an Aflas gasket, and Hydrochloric Acid (37%), Phosphoric Acid (85%), Sodium Hypochlorite (<16.5%), Hydrogen Peroxide (50%), Ferric Chloride (50%), and Ethylene Glycol (100%) all carry a 1.5 SG requirement.If your service is on that list, ask us about a heavier-rated tank rather than pushing this one past its rating.Full detail lives on our chemical compatibility resource.
