Plastic Caps, 38/439 Teflon Lined Ribbed Black Phenolic Caps

Next Page

These 38/439 black ribbed phenolic caps with Teflon liners are designed to provide secure, chemically resistant sealing for a wide range of liquid packaging applications. These durable black lids are compatible with our 4 Liter glass jugs. The ribbed exterior offers improved grip for easier application and removal, making these caps practical for both manual use and production environments. The phenolic construction could provide strong durability and resistance to a variety of formulations, while the Teflon liner may help support compatibility with more aggressive liquids such as solvents, laboratory chemicals, essential oils, and specialty blends. This combination is designed to help support leak resistance and maintain product integrity during storage and transport. These caps are available in two case sizes to support different operational needs—smaller quantities for lower-volume use or testing, and bulk cases for high-volume production and ongoing supply. This flexibility makes them suitable for laboratories, manufacturers, and contract packers who require dependable closures in scalable quantities. The ribbed design offers improved grip for easier application and removal, while the tamper evident feature may help provide visible evidence if a container has been opened. This makes them a practical option for applications where product integrity and consumer confidence are important considerations. The F-422 liner could offer compatibility with many liquid formulations, including chemicals, laboratory solutions, extracts, and other specialty products. These caps may be suitable for use in industrial, commercial, laboratory, and manufacturing environments where secure sealing and dependable performance are required. Read More...
