When using vacuum screws, blind holes can be effectively vented. With the help of our vacuum-optimizing washers, the areas under the screw head are also reliably vented. When conventional washers are used in vacuum systems, gases collect in the through-hole below the screw head. This poses the risk of a virtual leak.
With VOC washers, your systems can be pumped out more effectively, the process pressure can be reached more quickly and maintained for longer! Virtual leaks in your systems are effectively eliminated and there are no disadvantages compared to conventional washers without venting grooves.
Our vented VOC washers are permanently in stock and available in various nominal sizes. Of course, these are also available from stock as silver-plated versions and in other materials on request.
