An Oil Cooler Hose provides a direct and unobstructed pathway for the flow of coolant from the radiator to the engine. By delivering a consistent and regulated flow of coolant, the hose contributes to the optimization of the engine's operating temperature.Attributes:• The inner diameter gradually changes from 50.8mm to 76.2mm• Provides consistent flow for reliable operationApplications:An Oil Cooler Hose transfers hydraulic fluid to and from an oil cooler, which helps regulate the temperature of the hydraulic fluid to ensure optimal performance.
