Usually, development of automobile brake hose and power steering hose has been realizedthrough evaluating several actual prototype hoses experimentally. Recently, high durability and highdevelopment effect for brake hose has been required because periodic exchange for the brake hosehas not been requested any more. In this study, therefore, stress analysis by FEM is performed to thecrimped portion of hydraulic pressure brake hose in order to promote the development of theautomobile hoses more efficiently. It is found that large normal stresses σr in the radial directionappear at the crimped portion between the nipple and inner rubber. The results suggest that severalgrooves on the nipple surface may be useful because they cause large σr, which may improve thesealing performance. The effect of permanent deformation of the rubber on the sealing performanceis discussed by assuming initial deformation of the rubber at the crimped portion
