Standard Inverted Cone Fitting, 1/4-28 UNF and M6 (CAT#: STEM-AL-2663-ZJF)

This standard inverted cone fitting is designed for connecting rigid tubing to threaded fluidic ports. It is available in PP, PTFE, POM, PFA, and related material configurations. The fitting supports 1/4-28 UNF and M6 thread specifications. It accommodates rigid tubing with several outside diameters. The connection consists of an inverted cone plug used together with a separate compression ring. Installation is completed by placing both components over the tubing and threading the plug into the port. The straight-thread structure allows the connection to be assembled without additional tools. Its simple reusable configuration is suitable for routine fluid-line installation and maintenance.
