Smith Contractor 190504 Sprayer is a commercial grade, multi-purpose, 1-gallon sprayer for cleaning, sanitizing, applying harsh chemicals as well as lawns and gardens. Sprayer features a lockable shut-off to reduce hand fatigue; a nickel-plated brass poppet for strength and precision; and an easy-to-clean, in-line filtration system. Viton seals offer the best chemical resistance to chemicals and are easily changed without using tools. The pressure release valve safely releases pressure from tank prior to opening to prevent accidental chemical spray. Multiple nozzles included for ultimate versatility: adjustable poly and brass nozzles (enables stream to cone patterns), 2 flat fans, and a high performance foaming nozzle. Also accepts Tee Jet nozzles.
