MetaloSeal™ metal bead gaskets
- e.g. compressor seals
- Thanks to numerous combination options for metals and elastomers, can be adapted precisely to the relevant requirements
- Functional coatings, e.g. conductive coating for EMC shielding
- Installed in direct line of force
- Positioning plates and retaining clips for quick and reliable installation, vertical and upside down
- High media, temperature and pressure resistance
TopSeal™ deep-drawn covers
- e.g. service cover, FCCU cover
- Topographic support of the integrated seal using embossed stoppers
- Improved corrosion resistance
- With functional integration, e.g. screws, ventilation elements
Best possible screening against electromagnetic radiation
