PURPOSE: A hydraulic durability testing apparatus is provided to allow testing to be performed in a convenient manner and reduce cost by reducing the frequency of test and test period. CONSTITUTION: An apparatus comprises a cylinder block(10) having a predetermined space(11) formed inside the cylinder block, wherein the space is affected by a pressure; a cylinder head(20) disposed onto the cylinder block so as to seal the space formed in the cylinder block; a gasket(30) interposed between the cylinder block and the cylinder head so as to maintain an air tightness; a head bolt(41) for assembly of the cylinder block, cylinder head and the gasket; a pipe(51) arranged in the space formed in the cylinder block; and a hydraulic connection pipe(52) connected to an end of the pipe so as to allow hydraulic pressure to be supplied to the space formed in the cylinder block.
