Plastic Screw Cap. Fits most 5th and 10th size screw cap wine bottles. Has a plastic liner for excellent sealing.
The cone lined cap provides a wedge type seal that not only seals across the top of the container, it also seals across the inside diameter. This liner is stress crack resistant and offers superior torque retention and excellent sealing characteristics. This liner is commonly used for liquid products, and should be tested first to make sure leaking does not occur.
