Product Code:SAE J1402
Title:Automotive Air Brake Hose and Hose Assemblies
Issuing Committee:Hydraulic Hose And Hose Fittings Committee
Scope:This recommended practice covers minimum requirements for air brake hose assemblies made from reinforcedelastomeric hose and suitable fittings for use in automotive air brake systems including flexible connections from frame toaxle, tractor to trailer, trailer to trailer and other unshielded air lines with air pressures up to 1 MPa, that are exposed topotential pull or impact. This hose is not to be used where temperatures, external or internal, fall outside the range of-40 °C to +100 °C.
