Norwesco 110 Gallon Plastic Applicator Saddle Tank in White

The Norwesco 110 Gallon Applicator Saddle Tank (SKU N-45053) is a white polyethylene specialty tank built for fertilizer and applicator work where the tank rides on a saddle stand or sprayer frame.It holds 110 gallons, weighs 40 lbs empty, and carries a 1.5 specific gravity rating with an FDA-approved resin and a 120 F / 48 C maximum service temperature.The tank measures roughly 41 in long by 30 in wide by 34 in high, with a 1.25 in outlet and an 8 in lid.If you are sizing a rig or comparing it against other applicator and saddle tanks, the numbers below tell you whether this Norwesco tank fits your load, your frame, and your product.

Will it handle your load?

The 1.5 SG rating is the number that decides most applicator jobs.Full of water, this tank carries about 917 lbs; loaded to its maximum rated 1.5 SG contents, it carries up to 1,376 lbs.Your saddle stand, trailer, or truck frame has to support that weight plus the tank, so plan mounting hardware and axle capacity around the 1,376 lb figure, not the empty 40 lbs.Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm your product's weight per gallon before you spec the frame.Because this is a portable applicator tank, review the DOT scope first: our guides on Norwesco applicator and leg tanks and Non-Roadable Trailer (NRT) scope and the 49 CFR 173.5 agricultural exemption explain how farm-fleet use is classified.

Chemical compatibility

This tank uses an HDLPE resin at a 1.5 SG rating.The resin code carries a "?" in our data, so confirm HDLPE versus XLPE with us before committing it to chemical service.For a fertilizer applicator, the natural fits are DEF (32.5%) and urea solution (50%) — both rated at 1.5 SG, comfortably under this tank's 1.5 rating.DEF is the exception on fittings: it requires 316 stainless, not the PVC or PP used for most other products, so do not order PVC fittings for DEF.Per the Snyder Industries OEM chemical-resistance chart, the 1.5 SG tank is also rated for acetic acid (60%), aluminum sulfate (50%), calcium chloride (40%), ferrous sulfate (20%), magnesium chloride (30%), sodium carbonate (30%), and ozonated water (up to 10 PPM), most with PVC or PP fittings and EPDM gaskets.That chart is concentration- and temperature-specific: ratings assume ambient service and de-rate as you approach the 120 F / 48 C ceiling, so hot product or a solar-heated dark mounting frame must be confirmed against the chart before you fill.Always match the exact chemical, concentration, temperature, fitting, and gasket first.

The mistake to avoid

Do not put a denser fluid in this 1.5 SG tank than it is rated for.Heavier products need a 1.5 SG-rated tank: ethylene glycol, ferric chloride (50%), hydrochloric acid (37%), hydrogen peroxide (50%), phosphoric acid (85%), sodium hypochlorite (<16.5%), and sulfuric acid (98%) all require a higher-SG tank, not this one — and several call for Viton gaskets rather than EPDM.Peracetic acid (30%) is stricter still, needing 316SS fittings with Aflas gaskets.If your product is on that list, call 866-418-1777 and we will spec the right higher-SG tank and gasket for it.Start at our chemical-compatibility reference when in doubt, and check the technical drawing on this page to confirm the outlet and lid positions match your plumbing.
