Aluminium Screw Cap PP28 with Hole

The aluminium cap with hole for PP28 thread is designed to work with pierceable septa, allowing extraction or injection using a needle without opening the bottle and enabling more convenient, faster and controlled dispensing.

Manufactured from aluminium with a resistant metallic finish, it features a central hole designed to hold the septum. Its ribbed edge improves grip during handling and helps ensure firm screwing onto the container. To complete the closure system, this model can be combined with the pierceable butyl septa also available in our catalogue.

This cap is suitable for sampling, formulation, dosing and technical liquid handling processes where controlled access to the contents is required while maintaining the functionality of the cap-septum assembly.
