Pikotek® PGMTM

The PGE™ was designed to give operators an alternative to the failure prone phenolic-based isolating
gaskets. The unique design of the PGE™ system incorporates patented overlapping and offsetting seal
grooves. The purpose of this design is to break each layer of laminate within the gasket itself, thereby
creating a barrier through which fluid and/or gas cannot migrate. The sealing element can be any
elastomeric material, as well as more sophisticated spring-energized PTFE lip seals. As a result of this
advanced seal design, maintenance-free flange isolation and flange face corrosion mitigation are
achieved economically. Depending upon the sealing element selected, the PGE™ is rated for most
hydrocarbon and water service applications.

This gasket is suitable for use in raised-face and flat-face flanges in ANSI Class 150, 300 and 600
service¹ (or equivalent). In addition to providing electrical isolation, the gasket is excellent for isolating
flanges made of dissimilar metals or where prevention of flange face corrosion is desired.
