This Fire Hose Nozzle 40 Durable is designed to fit onto your garden hose to turn it into a powerful jet-sprayer with the power of a fire hose. Its jet spray can spray over 40 to power wash high up or hard to reach areas. With the adjustable nozzle you can use the powerful jet spray to clean away stuck-on dirt or mud on your car and then switch to a light rinse to gently wash away soap or anything else. You can easily give your car or home the power wash it deserves with this nozzle and your own hose.
