A hermetic seal is a crucial component for establishing enclosed environments, particularly within base building endeavors in the game. Its primary function is to create an airtight barrier, enabling the pressurization of interior spaces. This functionality is especially important for habitation on planets with hazardous atmospheres, allowing players to construct safe havens.
Obtaining this component unlocks opportunities for constructing underwater bases and enclosed vehicle bays. These structures offer protection from environmental threats and enhance resource gathering efficiency. Prior to its introduction, players faced limitations in exploring certain biomes and managing resources on hostile worlds. This component provides a significant advantage, expanding base-building options and gameplay possibilities.
