These typically require a full turn before the closure is properly applied. 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 89-400 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.
