Blue Mule Ultimate Wash System 2 for Professional Pet Grooming Ideal for pet bathing but has countless possible applications. Apply 2 shampoo or conditioner products as a fur-penetrating spray, then easily rinse using the same hose and nozzle.. Injector body is machined from industrial-grade chemical resistant polypropylene, not fragile molded plastic - This equipment is built to last with almost zero maintenance. Lower flow rate (2.3 GPM @ 40 PSI) than many other pet bathing systems reduces chemical consumption and water costs. Includes: 10' discharge hose, 10' water supply hose, ball valve injector assembly, custom machined 5-hole spray nozzle, two 6' chemical suction tubes with strainers, 20 color-coded precision metering tips to set dilution ratios.
