CONNECTION FOR PNEUMATIC TUBES

摘要

A connection for pneumatic tubes includes a first resilient tube and a second resilient tube. A ribbed fitting defines annular ribs and an axial lumen. A first end of the ribbed fitting is disposed in a first end of the first resilient tube. A second end of the ribbed fitting opposite the first end of the ribbed fitting is disposed in a second end of the second resilient tube. The ribbed fitting fluidly connects the first resilient tube to the second resilient tube. A connector shell is to radially compress the first and the second resilient tubes against the ribbed fitting to prevent a compressed gas from leaking between the annular ribs and the first or the second resilient tube. The connector shell has a 90 degree internal elbow to hold a 90 degree bend in the second resilient tube.
