The spiral gasket for exhaust piping (code K 81130) is a vital sealing component of the Sulzer ZV40/48 engine, designed to prevent gas leaks in exhaust systems operating under extreme conditions. Its spiral construction ensures a secure and flexible seal, accommodating thermal expansion and vibrations typical in marine and industrial environments. This gasket not only enhances engine efficiency but also contributes to environmental safety by reducing emissions. Replacing the gasket at recommended intervals is crucial to maintaining the integrity of the exhaust system and ensuring compliance with stringent operational standards.
