What Is an Expansion Plug?
An expansion plug is a component primarily used in engines and automotive cylinder blocks.
Designed to accommodate the expansion and contraction of mechanical components and systems under different temperature and pressure conditions, it is utilized in various applications. When an engine operates, the heat generated internally causes expansion of the engine block and coolant within the cooling system. Expansion plugs absorb this expansion, allowing the coolant to expand appropriately within the system without exerting excessive pressure. Conversely, when the engine cools down, the expansion plug contracts to maintain proper pressure within the cooling system.
Expansion plugs are typically made of rubber or metal and are resistant to thermal expansion and contraction.
