rubber seal

[cingolo]

Hello everyone!
I would like to create a cylindrical shape seal but with laughter on a contact face of an object (the compression happens on the opposite side of that face, the lateral surface is in contact with walls of a tube), I thought to simulate the operation of the seal.
making the seal part flexible is the right way or do other methods exist?

thanks to who will answer me

you can make flexible the presence of a cutting feature that sideways the seal.

Thank you for your answer:
I try to see what I can do with this method
