Abstract: A gladhand coupler assembly is configured to releasably couple to a gladhand coupler having a mating seal and first and second mating structures. The gladhand coupler assembly includes an assembly mating seal for interfacing with the gladhand coupler mating seal and first and second assembly mating structures coupled to the assembly mating seal. The first and second assembly mating structures are configured to interface with the gladhand coupler first and second mating structures, respectively. The gladhand coupler assembly further includes an actuation mechanism configured to move the assembly mating seal relative to the pair of rigidly fixed assembly mating structures. The gladhand actuation mechanism is further configured to place the assembly mating seal into and out of fluid communication with the gladhand coupler mating seal.
