The insert base is similar to the original factory toothed base, but with one change: it has its own housing and drilling that allows you to change the insert only when necessary, reducing costs.

By incorporating an insert, it offers greater precision and efficiency when threading, providing additional stability in use. Fixed by two screws, it has teeth at the top that firmly lock the bottle, ensuring stability during threading.

Made from hardened material, the insert undergoes a hardening process that significantly increases its resistance to wear and tear and prevents rusting. preventing rusting, making it ideal for demanding, high-performance industrial applications.
