The Chapin® Industrial Concrete Sprayer with Viton® has a 13L Tri-Poxy® lined steel tank that provides triple protection against rust, corrosion and damage from denting. A large 101mm wide mouth opening allows for easy filling and cleaning. The brass wand has a brass shut-off and brass fan tip nozzle to provide even coverage. The 1.2m reinforced hose with threaded fittings and Viton® seals is suitable for most concrete sealer applications (check chemical manufacturers instructions before use). Our open head tanks have a unique Tri-Lock® seal that insures the pump cap locks tightly into place.
