These gaskets are designed with a steel core that is rubber coated and have full perimeter elastomer beading on sides. The result is a gasket that will not split or extrude during installation and has good torque retention.
There is no set up time because installation is dry with no sealant needed.

NOTE
Amazon is responsible for the delivery of our products, and it may be mispackaged, resulting in bending or deformation due to the thin body of the gaskets. If the gaskets are damaged due to logistics, we will help you solve the problem as we can.
