The Landajet Rotating Nozzle gives you a high quality rotating nozzle at a great price. The 0-degree nozzle oscillates in a pattern that covers about the same area as the standard fan nozzle. Because the pressure is concentrated by the 0-degree nozzle, you get greater cleaning efficiency from your pressure washer, but still cover the same area as a fan nozzle. This is a #060 nozzle, and is recommended for 3600psi maximum pressure, with a maximum temperature of 190F. The inlet is 1/4" FPT. We recommend using a 87101490 high-pressure filter in the inlet of the nozzle to protect it from any foreign material, which could damage the internal moving parts and delicate ceramic seats.
