FEP/PFA Encapsulated Seal is consisted of a seamless and uniform Teflon FEP encapsulation which completely encloses a core material of either silicone or Viton elastomers. The combination of these components creates a seal that is virtually chemically inert and compression set resistant for use in harsh sealing environments.
·High Chemical Resistance
·Outperforms solid PTFE O-Rings
·Wide Temperature Range
·Non Stick Surface
·Low Coefficient of Friction
·Sanitary
·Unlimited Sizes
·Low Compression Set
·Many dimensions are available
Encapsulated Seal VS Solid PTFE :
A standard elastomeric seal has inadequate chemical resistance for a specific application, and A solid PTFE seal does not offer sufficient elasticity for reliable,long-term fluid sealing.These are held in a variety of general and high performance elastomers to suit the vast majority of industrial and specialised oil & gsa sector applications.
