Flex Connector - Hose Length for Degree of Bend

on . Posted in Flex Connector Datasheets

  • flex connector bend deflection 1To determine the centerline bend radius required.  Under the column headed "Centerline Bend Radius (in)", find the radius and read horizontally to be desired degree of bend (45°, 90°, 180°).  The number in the column will be the minimum live hose length required to make the degree of bend along the centerline radius.
  • Add fitting dimension "C" (end connection) to each end of hose for overall length.
  • For calculating length of hose see angular deflection.
