Title:Power Steering Pressure Hose--Low Volumetric Expansion Type
Issuing Committee:Automotive Brake And Steering Hose Standards Comm
Scope:This SAE Standard covers hose fabricated from fabric braid and synthetic rubber, assembled with end fittings for use in automotive power steering applications at pressures as indicated in Table 1B, as flexible connections within the temperature range of -40 脳C (-40 脳F) to 121脳C (250 脳F) average, 135 脳C (275 脳F) maximum peaks.These hoses are intended for use in applications where reduction in amplitude of pump pressure pulsations is not required.
