Anti-Twist Male Threaded Fitting, 1/4-28 UNF (CAT#: STEM-AL-2688-ZJF)

This anti-twist fitting is designed for threaded fluid connections where tubing rotation must be minimized. It is available in PP and PPS material configurations. The fitting uses a 1/4-28 UNF male thread. The tubing remains stationary while the fitting is tightened or loosened. A stepped flat surface is positioned at the male-threaded port. Sealing is created by threaded compression between opposing flat surfaces. This structure reduces torsional stress transferred to the connected tubing. It is suitable for fluid systems requiring repeated assembly or stable connection orientation.
