【Zero Leakage & Quality Material】Durable, strong and rustproof connector for secure and leak-free connection to pressure washers, lances and nozzles. The pipe cleaning hose is flexible, weather-resistant, oil-resistant, abrasion-resistant and ozone-resistant and comes with waterproof tape to prevent leakage. 【Swivel Nozzle】The swivel nozzle (4.5 opening diameter) is small enough to allow cleaning in all tight spaces. By turning the nozzle upside down into a clogged pipe and moving the nozzle into the pipe, the swivel nozzle helps to clean and flush out debris. 【Perfect Connection】 The plastic connection in the adapter is for use with Karcher K-Series pressure washers and lances, and the metal connector helps the hose connect to LAVOR household pressure washers (for non-threaded quick connect guns only). Once you get the hang of it, it is very easy to use. 【No Dead Space Nozzle】 Nose-shaped sewage ejector nozzle with 1 front jet and 3 rear jets. Featuring 3 rear undercuts with a 33°
