Jacket gasket with soft pliable core, surrounded by a metal jacket that totally or partially encloses the filler material. Partition bars can be incorporated , integrally or welded into the gasket. Jacketed is made by hands, and welded. Soft pliable core within thin metal covering. Wide choice of jacket and filler materials.
Types of Jacket Gaskets
Metal jacketed gaskets
Metal jacketed gaskets are the most basic type of semi-metallic gaskets combining the high pressure suitability and blow out resistance of metallic materials. The gaskets offer an economical seal where sealing faces are narrow and can be produced in a variety of shapes, making them a good option for heat exchanger jointing.
Stamping jacket gasket
Stamping jacket gasket by punch machines, the gasket with soft pliable core, surrounded by a metal jacket that totally or partially encloses the filler material. Partition bars can be incorporated , integrally or welded into the gasket. Whole face gaskets have perfect sealing stability.
Typical applications
* Heat exchangers
* Exhaust gaskets
* Valve bonnet gaskets
* Narrow flanges
