The invention relates to the field of sealing and particularly relates to a rubber barrel with relatively hard upper and lower end parts, which is used in an oil exploitation process and can bear high temperature and high pressure, a packer and a bridge plug. According to one aspect of the invention, the rubber barrel is provided; and the hardness of the upper end part of the rubber barrel is greater than that of the middle part of the rubber barrel, so that the deformation of the middle part in the radial direction is greater than that of the upper end part in the radial direction when the upper end part bears first axial pressure. The hardness of the upper end part of the rubber barrel is greater than that of the middle part of the rubber barrel, so that the upper end part is almost used for transmitting the first axial pressure to the middle part and the lower end part, but not utilizes the first axial pressure to self radial deformation when the upper end part bears the first axial pressure. Therefore, the middle part and the lower end part have the radial deformation when the relatively small first axial pressure is used, and the sealing of the whole rubber barrel is realized.
