38/430 White Smooth Straight PP Buttress Cap / Unlined

The 38/430 designation should be verified dimensionally because nominal finish names do not guarantee identical sealing behavior. Part 137880 should be judged on technical fit, line performance, and the finished user experience. Its application range extends to cosmetics, personal care, wellness, supplements, household, and specialty products. 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.
