【Quick Connection & Easy to Use】This pressure washer lance is designed for garden hoses and comes with standard 3/4" and 1/2" garden hose connectors and a quick connector. No need to purchase additional adapters, you can quickly connect and use it. Please note that the pressure of the product mainly depends on the pressure of the water system. 【Leak-proof and Rust-proof Material】Our water jet pressure washer is made of solid copper interfaces, a metal wand, a thickened switch, and a non-slip handle, ensuring that it is resistant to corrosion and rust. Its solid design and advanced materials make it resistant to rust, deformation and breakage over time. 【Easy to Use】Super easy to screw onto your current hose. For jet nozzles, simply remove the spring head, push the nozzle in and release the head. Make sure it locks into place. If you still see the little silver balls, you haven't put it in correctly. There is a small on/off valve on the handle that you can turn the water on or off
