Flat GUFERO sealing rings (sealing rings, gaskets, sealing washers, flange packing, shape sealing) refers to machine components that allow sealed joints to be created due to their sealing properties. By sealing, leaks of the sealed liquid through the seal of the machine parts will be either eliminated or reduced to the required level.
Flat sealing rings are used in particular in removable joints such as compressed seals in immovable components. These seals are suitable for applications in chemical facilities, for connecting pieces of pipes, valves, etc.
Flat sealing ring CU (copper washer) refers to an all-metal copper seal designed for the highest pressure class where a maximum sealing effect is achieved through metal-metal contact.
by the external diameter of the flat sealing ring (washer) x the internal diameter of the flat sealing ring (washer) x the thickness of the flat sealing ring (washer)
Copper washer - Flat sealing ring CU withstand operating temperatures within the range of: -40 to +700 °C.
Flat sealing rings are used to a greater extent in chemical facilities for the connection of fittings in pipes as sealing washers under screw connection sockets, etc.
DIN standard for flat sealing rings AL (aluminium) - DIN 7603A. Flat sealing rings are machine components allowing sealed connections to be created due to their sealing properties. The size of the flat sealing ring is defined as follows:
Application:
Flat sealing rings are used to a greater extent in chemical facilities for the connection of fittings in pipes as sealing washers under screw connection sockets, etc.
Aluminium washer - Flat sealing ring withstands the operating temperature within the range of: -195 °C to +200 °C.
Fibre washer - Flat sealing ring - FIBRE (flat fibre seal)
Flat fibre sealing rings (fibre seals) are most frequently used as flat seals in the form of flat washers under screw connections for removable joints. The operating temperature of flat fibre sealing rings (fibre seals) is within the following range:
