Double Jacketed Gaskets

Kaxite Double-jacketed gaskets are probably the most commonly used style of gaskets in heat exchanger applications. Double Jacketed Gaskets are used on boiler and heat exchanger applications when ample bolting is available to correctly seat the gasket. They are designed for high pressure and temperature applications up to and inclusive of Class 900.

KAXITE double-jacketed gaskets are particularly suited for applications like heat-exchangers and boilers. The gasket is constructed of a soft, heat resistant, non-asbestos filler material,which is completely enclosed in a two-piece metal jacket. When pass partition bars are required, we offer a welded pass bar construction. With a welded pass bar arrangement the fluid is retained by the primary seal at the inner diameter of the gasket.Thus the primary seal maintains its function, providing a seal of higher integrity.

A double jacketed gasket consists of a curved metallic tube with a wide C-shaped profile, and a second metal piece that bridges the inside of the C-shape’s opening, with filler material filling the interior space. The overlap of the outer shell and the gap-bridging cover piece give the closest edges of the C-profile a double thickness. When in use, this thicker section bears the main burden of the compressed gasket and creates a reliable seal.

Material standard

• Metal jacket: carbon steel, soft iron, 304 (1.4301),
 316L (1.4404)
• Filler material: graphite
Many standard bar configur


• the metal jacket covering the filler material prevents
• ensures high elasticity and recovery
• nearly any dimension and shape can be made
• the welded construction of the bars results in two
independent seals: the primary seal at the inner diameter
and the secondary seal at the outer diameter.

Safety is Our #1 Priority

Using the wrong gasket or the wrong gasket material can lead to gasket failure, personal injury, or worse. That’s why Kaxite Company works hard to ensure that you receive the best, most effective, and safest double jacketed gasket for your application.

We use a series of questions, which we call STAMP, to guarantee that you get the right gasket for your unique needs. Please keep the following questions in mind when specifying your metallic double jacketed gaskets:

S: Size of the gasket

T: Temperature range in which the gasket will operate
A: Application—is it a heat exchanger? a valve? a pump? etc.
M: Media—what will the gasket prevent from leaking
P: Pressure range in which the gasket will operate
If we can’t provide the best and safest double jacket gasket for your application, we’ll help you track down the product for your needs—even if that means sending you to another supplier. If we can’t be sure that we’re selling you the safest option, we won’t sell you anything at all. Safety is and has always been our #1 priority.
