Ferrule replacement instructions for the Direct Adaptive Di-Ad™ HPLC column connectors

  1. Change ferrule after approximately every 50 insertions or when excessive ferrule wear is detected.
  2. To change ferrule, grasp it in the area of the groove with a pair of wire cutters using minimal pressure and gently pull the ferrule from the threaded stem, wiggling the ferrule if necessary.
  3. Insert a new ferrule into the threaded stem and screw connector into a column port to seat the ferrule.

The Di-Ad HPLC column connectors are designed to provide universal connection to any manufacturer’s 1/16th 10-32 port. Maximum pressure, 10,000 psi.
