E3 Black Phenolic X Tall Cap F217

For a production-intent package, the E3 Black Phenolic X Tall Cap F217 (Part 134440) offers a defined compression-molded closure rather than a generic starting point. Confirm thread fit, torque, liner performance, leakage resistance, and opening behavior on production containers. 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.
