Fluid-tight rivets are often used to enhance what aspect of an assembly?

Fluid-tight rivets are specifically designed to create a seal that prevents the leakage of fluids in an assembly. This characteristic is crucial in aerospace applications where components may be exposed to various fluids such as fuel, hydraulic fluid, or coolant. By using fluid-tight rivets, the integrity of the assembly is maintained, ensuring that no fluids escape and that the system operates safely and efficiently.

The sealing capability of these rivets is achieved through their design, which may include features like rubber seals or special coatings that ensure tightness against fluid pressure. This quality is essential in environments where mechanical failure due to leakage can lead to serious safety hazards or operational failures, thereby emphasizing the importance of maintaining fluid containment in critical assemblies within the aerospace industry.
