Plastic Caps, Black Phenolic Cone Lined Caps

The black phenolic cone lined caps are available in many sizes. 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.
