Product details

Double Jacketed Gasket  is made from graphite, ceramic, non-asbestos etc filler coated with thin metal jacket, like SUS304,SUS316,Carbon steel, cooper, soft iron etc. with excellent sealing performance, it can be used in sealing spots

of pressure vessels, exchanger heat, condenser, plain hole, etc. The Ripple Double Jacketed Gasket be used in

various pipe and flange.

Double Jacketed Gasket Application:

Double Jacketed Gasket is particularly suitable for sealing flat surfaces of heat exchanges, gas pipes, cast iron flanges, cylinder heads of engines as well as for boilers and other vessels.

By their sealing efficiently, provided by exerting strong pressure on circular rimes of the flanges, metal-jacketed gaskets can stand up to 30% deviation from the initial thickness, which is very useful in case of irregular or faulty flange rims. The chemical compatibility of the metal and the medium being sealed should be considered.

The filler material is completely enclosed by a two piece metal jacket, which covers both the inside and outside diameters and both contact surfaces. It is designed for high pressure and temperature applications.
