FC 218 Resistant O-Rings and Seals

FC 218 is also known as Trifluorochloroethane or R-218. It is a colorless, volatile, non-flammable halocarbon gas used primarily as a refrigerant and in aerosol propellants. It is used in domestic and commercial refrigeration systems, air conditioning systems, and heat pumps.

When rubber is exposed to FC 218, it can cause swelling and softening of the material, leading to a decrease in its strength and durability. Additionally, FC 218 can cause a decrease in the elasticity and flexibility of the rubber material, as well as an increased risk of cracking and other deformities. Furthermore, FC 218 can accelerate the oxidation of rubber, resulting in discoloration and premature aging. In some cases, FC 218 can also cause embrittlement of the rubber material, which can further reduce its strength and durability.
