The Military to U-174/U Plug Converter is a cable that allows you to use military-style headsets with civilian aircraft that have a U-174/U plug. It has a military-style plug on one end and a U-174/U plug on the other end, and is 18 inches in length. This converter cable can be useful for pilots who have a military headset that they would like to use in their civilian aircraft, or for those who fly both military and civilian aircraft and want to use the same headset in both. It can also be useful for aircraft owners or operators who want to use military-style headsets in their aircraft but don’t want to install a military-style jack.
