Chromatographiebedarf Upchurch Scientific® Super Flangeless Fittings are designed to provide significant improvements over standard Flangeless Fittings. The lock ring offers uniform compression on the ferrule while operating as a bearing against the nut. Thus, the nut can spin freely against the ferrule, preventing the tubing from twisting during the tightening process. This feature eliminates subsequent loosening of the nut, making the Super Flangeless system ideal for applications subject to vibration. These products are also well suited for connections that need to be broken frequently, since the lock ring holds the ferrule in place on the tubing until intentionally removed. Use the LT-300 Removal Tool to release Super Flangeless Ferrules from tubing for repositioning.
