    摘要： The packing according to the present invention is composed of a string-like body formed of an elongated tape-like packing material having at least one layer is repeatedly folded in direction at a right angle to the longitudinal direction thereof in a zigzag manner with peak portions and valley portions alternately formed. According to the packing, the string-like body cut into a predetermined length according to the diameter of a shaft with which it is to be used may be wound on the outer peripheral surface of the shaft with the width or thickness direction of the string-like body directed in the radial direction of the shaft. Thus, the packing is versatile with respect to the shaft diameter. The packing itself produces no slip in the axial direction of a shaft. This prevents the packing from protruding, thus eliminating stress release due to a decrease in volume. The packing is used with the string-like body folded in the three-dimensional directions. Accordingly, the shaft-following properties of the packing at the time when the same is worn, are satisfactory and the decrease in sealing properties is restrained.

    摘要： The composite gasket of the present invention has improved various properties which are different depending on use conditions, while ensuring sealing properties, by combining a seal material which is selected in accordance with the properties of certain sheet-like seal materials in a substrate. The composite gasket is configured by forming a plurality of slits in a surface of the sheet-like seal materials the slits extending in a thickness direction of the materials, and loading a seal material composed of a substance which is different from a material constituting the sheet-like seal material into the slits and the surface of the seal material.

    摘要： A gasket for use in sealing sanitary piping comprises an annular plate of porous polytetrafluoroethylene, the inner surface layer of the gasket being heat treated to form a pore-free fused solidified layer for directly contacting a fluid to be sealed. The fused solidified layer prevents osmotic leakage of sealed fluid. Since the solidified layer is formed only in the surface layer the intrinsic properties of porous polytetrafluoroethylene, such as flexibility and affinity, are retained. The gasket is made by inserting a tubular member with an internal heater into a porous polytetrafluoroethylene gasket so that the tubular member directly contacts the inner surface layer of the gasket. The tubular member is operated at a temperature of 420.degree. to 460.degree. C. and contacts a gasket for 10 to 30 seconds to form the fused and pore-free layer.

    摘要： By improving a metal gasket having a corrugated portion which is advantageous in sealing property, a non-asbestos gasket in which the sealing property is further improved is provided. A non-asbestos gasket has a three-layer structured sealing portion S configured by: a core layer 1A which is made of a plate of a metal, and which is formed into a concentric circle-like corrugated shape; and surface layers 2, 3 which are made of expanded graphite, and which are stacked on the front and back faces of the core layer, respectively. In an outer circumferential end of the sealing portion S, the core layer 1A is protruded from the front and back surface layers 2, 3 toward an outer diameter side. In an inner circumferential end of the sealing portion S, the front and back surface layers 2, 3 are protruded from the core layer 1A toward an inner diameter side, thereby covering the core layer 1A.
