When you need a high water flow, higher pressure hose nozzle, Chapin's 4697 firefighter industrial high flow spray nozzle does the job. The large on/off lever is easy to grab and push or pull to turn the water on or off. The twist nozzle is extra-large to grip and change the spray pattern from a heavy straight stream to a shower. Thermoplastic rubber coats the durable zinc body and it handles up to 250 psi of water pressure. Working nozzle pressure does depend on the water pressure available. Great for spraying vehicles, boats, cleaning outdoor furniture and equipment and even general watering and landscaping. Fits standard hoses with a threaded connection. Genuine Chapin irrigation accessory and backed by a 1-year limited warranty.
