Portable Dispensing System provides superior mixing and dispensing accuracy with 3M Twist 'n Fill Technology. Great for bottle, bucket and auto-scrubber applications. The flexible, efficient system is easy to use. Simply attach the reusable dispenser to the bottle of 3M concentrated cleaning chemical (sold separately), connect to a water source and fill. The result is accurate, reliable mixing, so the properly mixed cleaner that you need is conveniently available. Highly concentrated cleaners are designed to be used with cold water instead of hot, reducing energy use and helping to prevent a scalding hazard. Dispensing is controlled at a two-gallons-per-minute flow rate. System includes durable dispenser, 6' hose with pressure relief valve and connector, female and male quick connects and back flow preventer.
