Why Do Tri-Clamp Connections Loosen in CDU Liquid Cooling Systems? The Role of the 20° Ferrule Taper Angle

In data center CDU liquid cooling systems, reliable sealing of Tri-Clamp connections is essential. The 20° taper angle on the back of the ferrule flange plays an important role in transferring clamping force and maintaining sealing performance. Drawing on practical manufacturing experience, this article explains how ferrule taper geometry works, how machining deviations may contribute to loosening or leakage, and what quality factors matter for liquid cooling piping systems.
