G-303 Metal Jacketed Gasket

1. Definition:
the cladding materials are different metal panels of 0.1MM-0.5MM thick, and the internal cladding materials are made of non-metal materials.

2. Application:
those with simple shapes are applied in pipeline flange and sealing surface of internal-combustion machines, and those with complicated shapes are used in the flange cover of heat exchanger, etc. The general gaskets are 10-25 MM wide and 2MM-8MM thick, and can be used in a maximum work pressure of 6-10Mpa.
