What is the integral function of a gasket in caskets?

The integral function of a gasket in caskets is to ensure a proper seal against moisture. Gaskets are typically made from materials that can create an airtight or watertight seal when the casket is closed. This seal is crucial for protecting the body from environmental elements such as water and other contaminants, thereby helping preserve the remains for a longer period. Proper sealing prevents moisture from entering the casket, which is essential for maintaining the integrity of the remains and any personal items placed within.

While airflow, sound quality, and insulation may have their importance in different contexts, they are not the primary purpose of a gasket in caskets. The focus of the gasket's function is on providing a secure barrier against moisture intrusion. This assurance is particularly significant in various environmental conditions where a sealed casket can help protect the body throughout the burial process.
