The Chapin industrial water supply tank is built to last. The tri-poxy lined steel provides triple protection against corrosion, rust, and damage from denting. The hose is reinforced with nylon braid and vinyl core to resist chemical attack, crimping, cracking and leaking. The wide mouth makes filling and cleaning easy, and the tank comes with a 3-1/2-gallon capacity. The brass spray handle comes with a lock-on feature for fatigue-free continuous use, and the threaded coupling allows for easy removal. This water supply tank comes with a poly holster which keeps the wand and nozzle secure.
