STRUCTURE ECAP FEP or PFA encapsulated O-ring, is an O-ring consisting of a seamless and uniform FEP/PFA encapsulation which completely encloses a core material of either silicone or FKM elastomers. The dimensions of the ECAP FEP or PFA encapsulated O-ring are characterized by the inside diameter and the cross section (I.D. x C.S.). FUNCTION The seamless, uniform and integral FEP/PFA encapsulation of the ECAP PTFE encapsulated O-ring is responsible for the sealing effect, whereas the continuous reset and the constant pressure of the encapsulation onto the sealing point is accomplished by the elastomer core. The result is an overall sealing compression, increasing with medium pressure. The ECAP PTFE encapsulated O-ring behaves like a highly viscous fluid, any pressure exerted on the seal is transmitted practically undiminished in all directions. PROPERTIES 1) High chemical resistance due to the FEP/PFA encapsulation. 2) Operational temperature range of -196C/-320F to +205C/400F. 3) Anti-adhesive properties / non-stick surface. 4) Sterilizable - F.D.A. conform. See General Specifications. 5) Low vapor permeability and minimal water absorption. 6) Low compression set. REMARKS ECAP PTFE encapsulated O-rings are resistant to practically all chemicals due to the FEP/PFA encapsulation. The FEP/PFA encapsulation is integral and has no weak points such as obvious seams or overlaps. 98% of all technical applications are within the operating temperature range of the ECAP PTFE encapsulated O-ring.
