Tapings provide medical equipment with gas from a central supply unit for patient treatment. Todays standards are plastic bezels. They create large gaps in the wall and allow germ emission. New and optimized aspects: Intuitively handling by automatic catch while plugging equipment. Un-lock by pushing the disc. At the same time (!) the plugged equipment jumps out for easy removal. Long lasting due to stainless steel housing. Smooth surfaces ease cleaning. Rubber seal between tap and wall gaps can be prevented and dust-free connection is provided for the first time. All international code standards are possible. Easy maintenance. 3 languages.
