VR 40
Material
VR 40 is an asbestos-free gasket material. It consists of aramide fibers and other asbestos substitutes that are resistant to high temperatures and are processed with high-grade elastomers under elevated pressure and temperature.
Properties
VR 40 is the most economical gasket material in the VR range. The material which is resistant to oils and solvents is characterized by its very high compressibility and flexibility as well as outstanding gas sealability. VR 40 ensures very effective sealing even under low surface pressure.
Application
- for sealed joints that are subjected to low mechanical and thermal stress
- for sealing lightweight components with comparatively low surface pressure, e.g. valve covers, oil pans and covers in IC engines
- for transmissions, pumps, apparatus, and pipelines in the fittings and sanitary fields.
- for sealing engine, transmission, hydraulic and refrigerating oils, fuels, and solvents
- for sealing water as well as mixtures of water and antifreeze & corrosion inhibitors
Surfaces
As standard, both sides of VR 40 are coated with a non-stick, high-friction layer that greatly facilitates disassembly. In most cases, additional surface treatment is unnecessary.

The data quoted above are valid for the material “as delivered” without any additional treatment. In view of the countless possible installation and operating conditions, definitive conclusions cannot be drawn for all applications regarding the behavior in a sealed joint. Therefore, we do not give any warranty for technical data, as they do not represent assured characteristics. If you have any doubt, please contact us and specify the exact operating conditions.
