Technical Information:
Welch plugs, also known as core plugs or expansion plugs, are used to fill the sand casting core holes found on water-cooled internal combustion engines. During the engine block casting process, these holes are created to support internal sand forms and facilitate sand removal after casting has cooled. The plugs are press-fitted into the machined holes to seal the coolant passages.
Installation:
Proper installation requires the plug to be pressed into the hole using appropriate tooling. The cup design allows for a secure interference fit that creates an effective seal when properly installed with suitable sealant.
Compatibility:
This product is vehicle-specific and designed for engines requiring 14mm welch plugs. Verify compatibility with your specific engine application before installation.
