Metal Jacketed Gasket

Metal Jacketed Gasket is a thin metallic outer jacket that encloses a compressible, flexible filler. The metal case protects the filler from pressure, temperature, and corrosion while allowing the gasket to tolerate minor flange irregularities.  The Metal Jacketed Gaskets are made in many styles to suit the most demanding applications:

Single-Jacketed  – Jacket covers one sealing face plus ID/OD.
Double-Jacketed  – Two-piece jacket fully encloses ID, OD, and both sealing faces.
Use: heat exchangers, corrosive or higher-temperature service.

French Type Jacketed– Jacket folded around a soft core with exposed filler at the edge; economical.

Double Jacketed Corrugated – Corrugated metal element used as filler or as a solid corrugated core to increase resiliency.

Single Jacketed Overlap– Enhanced jacket integrity and leak resistance on the periphery.

Pass/Partition Bars – Integral or welded ribs (preferred for best seal). Any layout available.
