Chapin 31440 Compression Sprayer, 2 Gallon Stainless Steel Tank
What You Get
- Two gallon stainless steel tank, which resists both rust and the denting that kills poly tanks.
- 12 inch brass wand, stiffer and longer lasting than the poly wands on entry level sprayers.
- 42 inch reinforced hose, long enough to work a bed without dragging the tank along behind you.
- Adjustable poly nozzle, stream through to cone.
- 0.4 to 0.5 GPM at 40 to 60 PSI.
Important: This Sprayer Is Not for Sealers or Acid Cleaners
We sell a lot of paver sealers and hardscape cleaners, so we need to be direct about this. Chapin rates this sprayer for fertilizers, weed killers and pesticides. They publish no solvent rating and no acid rating for it. A solvent based sealer will swell and destroy the seals, and an acid cleaner will attack either the seals or the tank. Chapin makes purpose built models for both jobs and we would rather point you at the right one than sell you this twice.

Looking After It
- Do not store chemicals in the tank. Empty, rinse and drain after every use.
- Do not switch chemicals without a thorough clean. Residue cross contaminates the next batch even after rinsing.
- Release the pressure before opening. Every year someone opens a pressurised tank and wears the contents.
- Wear eye protection, and do not spray in windy conditions.
