Viton 'O' ring Seals - Warning.
The 'O' ring seals used in the CAF Digital furnace work tube assembly are
manufactured from Viton. Viton is combustible and decomposition occurs
at elevated temperatures. Decomposition products include Hydrogen
Fluoride, fluorinated hydrocarbons, Carbon Monoxide and Carbonyl
Fluoride. Hydrogen Fluoride is highly corrosive.
Although these seals should not be exposed to elevated temperatures
during normal use, the following precautions should be taken:
· Wear neoprene gloves while handling the seals.
· Dispose according to local regulations. Landfill is recommend. Burning is not recommended
except by an approved or licensed incineration agent.
