Intuitive™ torque-limiting fitting

A unique patented fingertight fitting with click feedback

The new Intuitive™ fitting system from IDEX provides trouble-free low-pressure connections every time. This is especially useful in places where you frequently exchange fluid path components, such as when connecting flash columns, in-line filters and eluent bottles.

The Intuitive™ fitting has a patented self-adjusting torque-limiting nut for low pressure applications, and provides a haptic feedback click when it has been sufficiently tightened. You never again have to worry about leaking connections, nor about overtightening and squeezing tubes or damaging ports. The click feedback is built to work for at least 80 repeated assemblies and is thus ideal in positions where components are exchanged frequently. Being designed for 1/4-28 UNF ports with for flanged, Flangeless™, and Super Flangeless™ ferrule designs, and available in versions for both 1/16” and 1/8” OD tubing, we are confident this is the most easy-to-use, flexible, and intuitive low-pressure fitting system available.

  • Click feedback for perfect tightening every time
  • Ideal for flash columns, inline filters, and eluent bottles
