Are fluororubber seals toxic? Under normal working conditions and working temperatures below +200 degrees, fluororubber seals are very stable and harmless.

However, when exposed to temperatures above 300 degrees, such as the flame of a gas cutting gun, the fluororubber seal will release harmful gases. Inhaling these gases or getting them into the eyes can be harmful to human health.

Once the fluororubber seal is heated to a temperature above 300 degrees, it is dangerous to handle it even after cooling, so it must not come into direct contact with the skin.

If you need to handle fluororubber sealed bearings that have been exposed to high temperatures before, you should observe the following safety precautions:

(1) Wear goggles, protective gloves and appropriate breathing equipment during the entire disassembly process;

(2) Place the removed seal in a sealed plastic container and mark the container with "corrosive material";
