Metal-Jacketed Gasket

XY-MG-MJG

A metal jacket encloses the filler; made to equipment drawings

A metal-jacketed gasket consists of a metal shell enclosing a soft or heat-resistant filler. Circular, oval, obround, and partition-bar configurations are available, with dimensions based on the equipment drawings. The jacket protects the filler and maintains the gasket's shape, while the filler accommodates minor irregularities in the sealing surfaces.

  • Metal jacketProtects the filler and keeps the gasket shape
  • FillerHelps the gasket conform to the sealing faces
  • Made to drawingSpecial shapes and pass-partition bars possible

Features

  • The metal jacket protects the filler and can be formed into a variety of equipment gasket profiles.
  • Available in single-jacketed, double-jacketed, corrugated-jacketed, and partition-bar configurations.
  • Large-diameter, custom-profile, and partition-bar gaskets are manufactured to agreed equipment drawings and joint requirements.
  • Jacket and filler materials can be selected to suit the medium, temperature, and flange conditions.

ConfigurationsSingle-jacketed, double-jacketed, corrugated, partition-bar, and custom-profile designs

Standards & supply options

  • Made to heat exchanger and equipment drawings, with custom profiles, partition bars, sealing widths and joints. Double-jacketed constructions are made to equipment drawings.

Typical applications

  • Shell-side, tube-side, and channel-cover sealing in shell-and-tube heat exchangers.
  • Pressure vessels, reactors, process columns, and large-diameter equipment flanges.
  • Industrial equipment requiring circular, oval, obround, or partition-bar gaskets.

Selection & service notes

Suited to equipment joints providing relatively high, uniform assembly loads and suitable flange flatness and rigidity. Custom options include profile, dimensions, partition-bar layout, sealing width and material combination to the equipment drawing.
