The crimp cover of the jaws is made of aluminum for crimping and sealing. The cap gasket is a septum material that is pierced by a syringe needle to extract a sample from the vial. The cap liner sheet has various configurations and is also made of various materials.

Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The crimp cap vial requires crimping tools to carry out the sealing process.
