Tool-free fitting

Tool-free fitting
Topic LCI-USG-0087, Last Updated 05/19/2025

Tighten the fitting finger-tight.

The tool-free fitting (TFF) enhances usability by eliminating the need for tools, reducing the risk of overtightening and leaks. Its design mitigates common connection issues, making it easier to achieve a correct and secure connection.

Note: Waters BioSuite columns and some non-Waters columns may leak when connected with the tool-free fitting. In this case, install an adapter between the column and the tool-free fitting. See Installing the tool-free fitting adapter.
