Plastic Screw Cap. Fits most 1/2 and 1 gallon jugs. Has a plastic liner for excellent sealing. Sold per each or bag of 72.
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.
