Dynamic seal is what?

Dynamic seal is what?

• A. Packing
• B. Gasket
• C. O-ring
• D. Lip seal

Answer: (B)

A gasket is the type of seal used between two mating surfaces to fill gaps and irregularities and maintain a seal even when the joint experiences movement, vibration, or thermal expansion. It is placed in a joint and compressed, allowing the material to deform slightly to stay in contact as parts shift, which is why it works well for dynamic sealing in assemblies where flats or flanges might flex or move under operating conditions. In many ALRE components, joints can undergo small movements or misalignments, and a gasket’s compressible nature helps preserve the seal through those changes. Other seal types are more specific to rotating shafts or specialized dynamic interfaces; gaskets provide a robust, general solution for dynamic sealing at flange-type joints.
