100/400 Silver Metalized Straight Sided Cap F217

The format can serve prestige beauty, wellness, pharmaceutical, supplement, and specialty-product packaging. Part 137100 should be judged on technical fit, line performance, and the finished user experience. The 100/400 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Confirm thread fit, torque, liner performance, leakage resistance, and opening behavior on production containers. Good component decisions here can prevent costly changes during scale-up.
