Order information
The shielding tape are supplied on coils.
Standard dimension: 16.5m/roll, 25mm/50mm width.
Compress mesh gaskets are utilized for high volume, custom engineered application.
Although most common are rings, gaskets can also be produced in rectangular or special shapes, with holes or mounting recesses, corner radii,and other custom features.
The gasket is formed by die-compressing a controlled amount of knitted wire mesh that contains no joints or splices.
