Hot and Cold Water Compatibility: The hose is specifically designed to handle both hot and cold water. It is constructed with materials that can withstand high temperatures, typically up to 300°F (150°C) or more. This allows you to use hot water for more effective cleaning in applications that require it.
High-Pressure Rating: The hose is designed to handle the high-pressure water flow generated by power washers. It typically has a high-pressure rating, such as 4000 PSI (pounds per square inch) or higher, to ensure it can handle the force of the water.
