The invention provides a gland seal which is easy to operate, high in sealing performance and capable of preventing knitted sealing gaskets from falling. The gland seal comprises the first sealing gasket (11) and the second annular sealing gasket (12), wherein the first sealing gasket (11) is made of expanded graphite, and the second annular sealing gasket (12) is arranged at the axial end of the first sealing gasket (11) and made of fiber materials through knitting. A concave part (13) is formed in the inner circumferential edge of the axial end of the first sealing gasket (11). The outer diameter of the second sealing gasket (12) is smaller than the outer diameter of the first sealing gasket (11), and the outer circumferential surface (12a) of the second sealing gasket (12) is embedded in the inner circumferential surface (13b) of the concave part (13), so that the second sealing gasket (12) and the first sealing gasket (11) are fixed into a whole. In an unused state in which the gland seal (10) is not pressed in the axial direction, the inner diameter of the portion, embedded in the concave part (13), of the second sealing gasket (12) is larger than that of the first sealing gasket (11). In a used state in which the gland seal (10) is pressed in the axial direction, the inner diameter of the portion, embedded in the concave part (13), of the second sealing gasket (12) is decreased, so that the portion, embedded in the concave part (13), of the second sealing gasket (12) and the first sealing gasket (11) make contact with a sealed surface (33a) on the inner side together.
