Coolant hoses are specialized industrial hoses designed to transfer coolant fluids in automotive, industrial, and marine applications. These hoses are typically made of synthetic rubber or silicone, reinforced with high-strength fibers or wire, to withstand the high temperature and pressure of the coolant system. Coolant hoses are designed to be flexible, durable, and resistant to abrasion, ozone, and weathering. They are available in various sizes and lengths, and must meet regulatory standards, such as SAE and ASTM, to ensure safety and reliability. Proper installation, inspection, and maintenance of coolant hoses are also critical to ensure safe and reliable operation of the cooling system.
