Silicone hoses are known for their flexibility, durability, and resistance to high temperatures and pressures. A hose with a 3/4-inch inner diameter is commonly used in automotive and industrial applications, such as coolant and heater systems. The "3.25" measurement likely refers to the length of the hose in inches.
