13/425 Black Phenolic Cone Lined Caps

Here Black Phenolic Cone Lined caps are available in 13/425 and 15/425 sizes. The cone lined plastic caps provide 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 paired with phenolic plastic caps is commonly used for liquid products and should be tested first to make sure leaking does not occur.
