The L009 is a silver metal 20-410 continuous thread cap with F217 liner. Continuous thread caps have a single thread on the inside of the skirt. These typically require a full turn before the closure is properly applied. The thread on this cap will strip easily if overtightened on a glass container. This closure includes an F217 foam liner, which will create an airtight seal when the lid is securely screwed on to the container. This closure fits a container with a 20-410 neck finish. The first number refers to the diameter of the container's opening (in mm). The second number refers to the thread/style/depth of the closure's skirt.
