The material of the hose is crucial for durability and flexibility. Most hoses are made from rubber, vinyl, or a blend of both. Rubber hoses are known for their robustness and resistance to kinks, making them ideal for heavy-duty use, while vinyl hoses are lighter and often more affordable. However, they may not last as long. If you frequently wash your car or have multiple vehicles, investing in a high-quality rubber hose may be worthwhile.
