What is the role of a gasket in a water tight door system?

A gasket in a water-tight door system serves the critical function of sealing against water. Its primary role is to create an effective barrier that prevents water from entering through the seams or gaps between the door and its frame. This is particularly important in environments where water ingress could cause damage or compromise safety, such as marine applications, flooding scenarios, or industrial settings.

The design and materials used for gaskets are chosen specifically to withstand pressure and temperatures associated with the application, and they need to maintain their sealing properties over time. Using appropriate gaskets ensures durability and functionality, reinforcing the integrity of the system against potential water damage.

In contrast, while insulation, aesthetics, and structural support are all relevant considerations in door design, they do not define the primary purpose of a gasket in this context.
