As a material, PTFE-Encapsulated Viton® offers long service life in aggressive chemical duty, excellent resistance to permeation and contamination. It resists aggressive oxidizers, steam, and nearly all process chemicals. Published continuous service range is -75°F (-59.4°C) to 400°F (204.4°C). It should not be specified for service in service requiring tight-radius dynamic flexing or installation over sharp edges without care.
