Smith Performance Sprayers are built to work as hard as you do. They are durable, professional products with an emphasis on chemical resistance and built to withstand the most demanding work conditions. The S103E 3.5-Gallon Industrial and Contractor Series Stainless Steel Concrete Compression Sprayer is a durable solution for a wide variety of concrete applications. It will withstand the toughest solvent- or water-based chemicals in the toughest work conditions - including etching chemicals, diesel, bond breakers, sealers, curing compounds and more. The easy-to-change Viton seals are throughout the pump and shut-off with a tank made from A-Grade AISI-304 stainless steel inside and out making this sprayer highly resistant to chemicals - no need for epoxy coatings. Features a 50-inch, synthetic rubber hose with nylon core for greater wear and chemical resistance against solvents and other harsh chemicals. The large, wide-mouthed opening is easy to fill; and the specially designed, four-prong locking mechanism seals the pump tightly against an internal O-ring. The S103E also offers a pull-button pressure release valve making it quick, easy, and safe to release internal pressure prior to opening the canister. Includes one brass flat fan nozzles - 0.5 GPM angled at 95 Degree. Also accepts Tee Jet nozzles. NOTE: Product may be used with solvent-based sealers and other concrete chemicals compatible with Viton based elastomers. Clean with water or Xylene. Remove liquid from wand and hose. Remove pump after cleaning to ensure adequate drying. Do not use acetone-based chemicals - acetone will cause issues with seals and gaskets resulting in undesirable performance.
