Womala Upper Hose O Ring 31370994 Hose Seal for Volvo V40 S60 Cooling Auto Parts

Core Functions

• Leak Prevention: The primary function of this O ring is to create a tight seal at the hose connections. In the coolant system, it prevents coolant leakage, which could lead to engine overheating. In the oil system, it stops oil from leaking out, avoiding lubrication issues. And in vacuum systems, it maintains the necessary vacuum pressure for components like the brake booster or HVAC controls to function properly.
• System Integrity Maintenance: By providing an effective seal, it helps maintain the integrity of the relevant vehicle systems. For example, in the cooling system, it ensures that the coolant can circulate efficiently to cool the engine, and in the vacuum system, it keeps the vacuum - operated components working as intended.
• Durability: The O ring is designed to be durable, with the ability to resist wear and tear caused by the movement of hoses and the pressure of fluids. This ensures long - term reliable performance, reducing the frequency of replacements and potential system failures.
