The invention discloses a liquid storage cup of a gasket material sealing testing machine and the gasket material sealing testing machine with the liquid storage cup. The liquid storage cup of the gasket material sealing testing machine is made of transparent polypropylene materials, and liquid storage-amount scales are marked on the outer surface of the side wall of the liquid storage cup. The liquid storage cup is arranged outside a control cabinet of a panel of the gasket material sealing testing machine. The liquid storage cup of the gasket material sealing testing machine is simple and reasonable in structure; due to the fact that the outer wall of the liquid storage cup is transparent, the storage amount of liquid in the liquid storage cup can be directly observed in a visual inspection mode from the outside of the liquid storage cup, and whether the storage amount of the liquid in the liquid storage cup meets the requirement for consumption of a test or not can be conveniently judged; due to the fact that the liquid storage cup is arranged outside the gasket material sealing testing machine, the stored liquid is prevented from splashing to short-circuit a line or to burn out a meter or an electricity meter; the weight is light, installation is firm, and the sealing effect is good.
