Industrial Core Plug is used to fill the sand casting core holes found on water-cooled internal combustion engines. These plugs are set in various places around the metal section bolted on top of the engine blocks and form the component of the combustion chamber. Primarily used in vehicles' engines, which comprise a 'water jacket' with a circulation of water, these products help engines to be at a constant temperature. Available at nominal prices, this Industrial Core Plug is also used in aesthetics, central heating boilers, general capping, non-water cooled engines, etc.
