Adapter, for use with Low to Medium Pressure HPLC. Waters female to 1/4-28 male connection, 0.4 mm bore size. PEEK 1 EA.

This finger tightened adapter makes changing from Waters male nuts to non-Waters connections very convenient.

The "flat" section on the knurled adapter allows for an extra 1/8 of clockwise turn for tighter sealing or a slight counterclockwise turn to help remove if a tight fitting is too hard for hand removal. The flat section can also be used to hold the adapter in place with a wrench while the Waters male nut is tightened in the adapter.

These adapters are excellent when using the Cogent Column Filters with Waters brand columns.
