O-rings used on chlorine equipment should be made out of what material?

Choosing Viton as the material for O-rings used on chlorine equipment is appropriate due to its exceptional resistance to harsh chemicals, including chlorine. Viton is a type of fluoroelastomer that can withstand high temperatures and is impermeable to many gases and liquids, making it particularly suitable for environments that involve chlorine usage. This resistance ensures that the O-rings will maintain their integrity and seal effectively, thus preventing leaks and potential safety hazards associated with chlorine exposure.

Other materials such as rubber, silicone, and plastic do not offer the same level of chemical resistance. Regular rubber may degrade in the presence of chlorine, while silicone, although it has good temperature resistance, may not withstand chemical exposure as well as Viton. Plastic, depending on the type, usually lacks the flexibility and sealing capability needed for effective O-ring performance in a chlorine environment. Thus, Viton is the material of choice for ensuring safety and longevity in chlorine equipment.
