Pikotek® PGE™ System Isolating Gaskets/Kits

The Pikotek® PGE™ is a low-pressure service isolation kit designed for electrical flange isolation and/or general sealing applications

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.

  • High-reliability, low-pressure sealing system
  • Provides excellent electrical isolation for cathodic protection systems²
  • Overlapping seals help prevent potential leak/weep path in the laminate material
  • Also available with a variety of elastomeric seals including spring-energized PTFE or O-ring pressure activated seals
  • Protects against flange face corrosion and flow-induced erosion
  • Available in ring (type F) style or full-face (type E) style
  • Superior sealing solution for low-pressure (ANSI class 150, 300 and up to 600) service
  • Pressure-activated seals provide high confidence sealing
  • High-strength laminate material resists failure due to excessive compression (i.e. over tightening bolts)
  • Reinforced laminate retainer material provides excellent isolation for cathodic protection systems
  • Gasket is sized to the bore, which protects flange faces from media-induced corrosion and flow-induced erosion
  • Mitigates galvanic corrosion in dissimilar metal flanges
  • Developed from proven PSI/Pikotek sealing technology
  • Spring-energized PTFE seal provides radial load and encapsulation in the seal groove, which eliminates cold flow
  • Easy installation, make up and removal
  • Self-aligning and self-centering gasket is quick to install
  • Low required bolt loads. Less make-up force is required, resulting in less flange and bolt stress
