It helps prevent engine oil leakage from open or unused hose ports, maintaining proper oil containment within the cooling system. It supports stable oil circulation by ensuring that flow paths remain properly sealed and directed. It reduces the risk of pressure loss within the oil cooling circuit, helping maintain consistent lubrication performance.Attributes:• Seals open or unused oil cooler hose ports securely.• Maintains proper oil pressure within the cooling circuit.• Supports controlled oil circulation through the cooler system.Applications: An Engine Oil Cooler Hose Pipe Plug Joint is located at the engine oil cooler hose connection point, where it seals open or unused ports to prevent oil leakage, maintain proper pressure, and support controlled oil circulation.
