Jacketed Gaskets

Metal jacketed gaskets, also known as clad gaskets, are widely used in heat exchanger applications. The jacket provides good stability and blow out resistance, while the filler forces the jacket to adapt to its environment, creating a strong seal.


Double Jacketed Gaskets



We offer double jacketed gaskets, manufactured in house, in a wide variety of materials with varying grades of filler. These gaskets are offered as plain rings or with pass bars (ribs).

Though most commonly filled with graphite, these gaskets can also be filled with other soft materials such as PTFE, for chemical applications, compressed non-asbestos fiber, and high temperature millboard.


Construction Types



Jacketed gaskets can be made in one piece or with a welded construction, often dependent on size. Though most commonly supplied as rings, double jacketed gaskets can also be provided in specific shapes to your design.

Product Types

Double Jacket: Excellent for high temperature applications. The filler is totally enclosed in a two-piece metal jacket.


Single Jacket: Good where narrow flanges are required. The filler is totally enclosed in a one-piece metal jacket.


Single Jacket Open Edge: Useful for when only the inside diameter requires the metal jacket protection.


We offer a variety of metallic jacket materials including:

  • Mild Steels: Including Soft Iron and CR4.
  • Stainless Steel: Including SS316L, SS304 and SS321.
  • Duplex Stainless Steel: Including standard and ‘Super’ grades.
  • Alloys: Including Alloy 400 (Monel) for chemical applications and Incolloys 600, 625 and 825 for high temperature.
  • Titanium
  • Copper

And soft fillers, such as:

  • Graphite: Used widely for steam, water and other basic applications.
  • PTFE: For use with potent chemical applications or on oxygen service.
  • Mica: Suited to high temperature applications.
