Metal Jacketed Gaskets
Parker Metal-Jacketed Gaskets are a practical answer to the problem of circular or non-circular sealing problems. This family of gaskets offers good compressibility and excellent compensation for flange irregularities and misalignment when high pressures up to 2500 psi (or higher, depending on joint design) must be contained.
Application:
- Offers good compressibility and excellent compensation.
- By selecting the proper style, almost any size or configuration can be produced.
Where Recommended – Parker Metal-Jacketed
Gaskets are ideally suited for smooth surface applications such as heat exchangers, valve bonnets, gas mains, vacuum lines, cast iron flanges, autoclaves, boilers and glass-lined equipment.
Recommended for use on circular and noncircular applications requiring minimum of 20 to 30 percent compressibility to compensate for flange misalignment, warping, etc. Parker Metal-Jacketed Gaskets are designed for use in assemblies where the elasticity of bolts or flange design can compensate for joint relaxation.
For joints requiring close maintenance of the compressed thickness or joints which mechanically limit compression (such as metal-to-metal), use of Parker metal jacketed geometry is normally not recommended.
How They Work – Parker Metal-Jacketed
Gaskets are fabricated with a soft, conformable filler, partially or wholly encased in a metal jacket. The primary sealing interface is the inner metal lap where the gasket is thickest when under compression.
This area flows into the flange surfaces to create the joint seal; therefore, the entire inner lap must be under compression. The outer lap, if any, when under compression between the flange faces provides a secondary sealing line.
Available Metal-Jacketed Styles – Parker Metal-Jacketed
Gaskets are produced in a wide range of cross-sections, each designed to provide optimum sealing in a particular application. These styles are shown at the bottom of this page.
