A Hub Lid helps maintain the proper functioning and pressure of the cooling lines. The lid is designed as a cap that securely seals the opening of the coolant reservoir or radiator. It is made of durable materials such as steel to withstand the high temperatures and pressures encountered in the cooling lines. The pressure relief valve opens when the pressure exceeds the specified limit, allowing coolant to escape and preventing damage to the cooling line parts.Attributes:• Prevents over-pressurization, which can lead to coolant leaks, component damage• Ensures proper coolant circulation and prevents hotspots or coolant flow disruptionsApplications:A Hub Lid securely seals the opening of the coolant reservoir.
