E3 Black Phenolic Ring Cap F217

The E3 Black Phenolic Ring Cap F217 is listed as Part 134420 and should be considered as part of the complete package, not in isolation. Product teams may consider it for prestige beauty, wellness, pharmaceutical, supplement, and specialty-product packaging. A premium cap profile still requires careful review of thread engagement, liner compression, and removal force. Before release, evaluate application torque, seal integrity, removal force, and distribution performance.
