How to Choose the Right Base Connector

Pick the connector that matches your shield style, bottle neck, and cleaning habits to avoid fit or performance issues.

  1. Shield Style: Confirm you have a two-piece shield design, since these bases are made for two-piece systems rather than single-piece shields.
  2. Bottle Neck Size: Choose narrow-neck or wide-neck connectors to match your bottles, the wrong neck size will not seal correctly.
  3. Count and Backups: Keep an extra pair on hand, so you can swap connectors while another pair is being sterilized.
  4. Cleaning and Sterilization: These parts are steam safe. Follow your pump and shield cleaning guidance, and sterilize parts as you normally would.
  5. When to Replace: Replace connectors if they crack, discolor, or leak, or if seals no longer form a secure connection.
