Chapin 31410 Compression Sprayer, 1 Gallon Tri-Poxy Steel Tank
What You Get
- One gallon Tri-Poxy lined steel tank. Chapin claims triple protection against rust, corrosion and denting.
- Four inch funnel opening, wide enough to fill and to get a hand in to clean.
- Poly shut-off with lock-on, so you are not squeezing a trigger for an hour.
- 42 inch hose and an adjustable poly nozzle.
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.

A Note on Acid and Steel
Worth saying separately from the seal question. Even if the seals could take it, an acid cleaner does not belong in a steel tank. Chapin builds its acid rated sprayers on poly tanks for exactly that reason. If you are spraying an efflorescence remover or an acid stain, the tank material matters as much as the gasket.
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.
