28/400 Black Phenolic Cone Lined (Polyseal) Cap

Phenolic rigidity supports a precise feel, but liner selection and torque remain central to reliable sealing. Appropriate markets can include prestige beauty, wellness, pharmaceutical, supplement, and specialty-product packaging. When the brief calls for a well-defined compression-molded closure, Part 134300, the 28/400 Black Phenolic Cone Lined (Polyseal) Cap, provides a practical specification to evaluate. Confirm thread fit, torque, liner performance, leakage resistance, and opening behavior on production containers.
