Gasket vs Diaphragm - What's the difference?

gasket | diaphragm |

As nouns the difference between gasket and diaphragm

is that gasket is any mechanical seal that serves to fill the space between two objects, generally to prevent leakage between the two objects while under compression while diaphragm is in mammals, a sheet of muscle separating the thorax from the abdomen, contracted and relaxed in respiration to draw air into and expel air from the lungs; also called thoracic diaphragm.

As a verb diaphragm is

to reduce lens aperture using an optical diaphragm.
