The unique feature of the VICI Jour column coupler is that it adjusts to fit all 10-32 fitting types. No matter what the fitting type and pilot length – Valco®, Waters®, Upchurch®, Rheodyne®, etc., the coupler adapts to bottom out in the pilot automatically, consequently creating only small void volumes. The column coupler is fingertight to 350 bar (5000 psi).
