The explosion-proof sealing bushing is a specialized electrical fitting designed to maintain the integrity of an explosion-proof enclosure. It's used to seal cable entries and prevent the passage of gases, vapors, and flames through the cable entry points, ensuring that any potential ignition within the enclosure does not spread to the surrounding atmosphere. This type of bushing is critical in hazardous environments, such as those found in the oil and gas, chemical, and mining industries.
