51/400 Silver Metalized Straight Sided Cap F217

Phenolic rigidity supports a precise feel, but liner selection and torque remain central to reliable sealing. Its application range extends to prestige beauty, wellness, pharmaceutical, supplement, and specialty-product packaging. Part 136260 gives development teams a focused basis for testing this compression-molded closure. Confirm thread fit, torque, liner performance, leakage resistance, and opening behavior on production containers. The best result will balance line efficiency with intuitive consumer use.
