Metal Jacketed Gasket
Metal Jacketed Gasket is composed of carefully selected cushion materials such as non-asbestos millboard, ceramic fiber, compressed non-asbestos sheet and PTFE sheet with external metal jacket of carbon steel, stainless steel, copper, etc. They are widely used on piping flanges, joints of machinery and heat exchangers because they can be fabricated not only to a regular round shape but also to other irregular shapes such as oval, rectangular, etc. with additional partition or partitions to seal multi-pass heat exchangers. An increased demand has recently been seen for a special type having attached expanded graphite tapes on both sealing faces to increase sealability.
