Material

Copper, aluminium or stainless steel 1.4571.

Version
Bright.
Note
DIN 7603 sealing washers Form A. They are used to seal static fastenings. They prevent liquids or gases from escaping and simultaneously protect the system against the ingress of dust, dirt and liquids.

Due to their resistance to corrosion, sealing washers made from copper, aluminium and stainless steel can be used anywhere, with the exception of some strong acids. Thanks to their soft structure, they mould themselves into any unevenness in the parts being screwed together, thus ensuring a tight seal.

The sealing washers are used with DIN 908 and DIN 910 screw plugs, and hollow screws.
Temperature range
Copper max. 300 °C.
Aluminium max. 200 °C.
Stainless steel possible to max. 550 °C. However, this always depends on the pressure and media being sealed.
Independent trials and tests should therefore be carried out under the specific conditions of use in order to ensure suitability and resistance in the respective application.
