Marine Refrigeration Sight Glass Gaskets are essential seals used in refrigeration systems to prevent leaks and ensure proper visibility of refrigerant flow. These gaskets are designed to withstand harsh marine environments, offering durability and resistance to temperature fluctuations. They play a critical role in maintaining system efficiency and preventing contamination in marine refrigeration units.
