PTFE O-Rings


Since the development of PTFE in the 1930's it has become a stable in industry for chemical and high heat applications (below 500 F). PTFE was first discovered by a Dupont engineer and was trademarked with a name associated with non-stick pans. Today, PTFE O-Rings are used in a wide range of FDA, NSF,Chemical, Aerospace, semiconductor, pharmaceutical and other industries that require a clean, compatible seal.
Because PTFE O-Rings are basically a plastic o-ring, they perform differently from Elastomeric o-rings. The lack of stretching, and recovery must be considered when designing for PTFE. In some applications an encapsulated FEP o-ring may be a better solution then a PTFE O-Ring, due to it's better recovery rate.
