Lateral Deflection

Written by Jerry Ratzlaff on . Posted in Properties

Lateral deflection is when a flex connector is bent off it's centerline and both of it's ends are parallel to each other.


\(l = \sq {6 rT+T^2}\)

\(l_p = \sq {l^2-T^2}\)


\(l\) = live hose length

\(l_p\) = projected live hose length (inches)

\(r\) = minimum centerline bend radius for constant flexing (inches)

\(T\) = offset motion to one side of centerline (inches)


  • When the offset motion occures to both sides of the hose centerline: \(2\) times \(T\)
  • The offset distance "\(R\)" for constant flexing should never exceed 25% of the centerline bend radius "\(r\)".
  • If the distance "\(l\)" and "\(l_p\)" is significant, take care at installation to avoid stress on the hose and braid at the maximum offset distance.
