The Pikotek PGE Flange Gasket is a low-pressure service gasket designed for electrical flange isolation and/or general sealing applications. This gasket is suitable for use in raised-face and flat-face flanges in ANSI class 150 and 300 service (or equivalent). In addition to providing electrical insulation, the gasket is excellent for electrically isolating flanges made of dissimilar metals or where prevention of flange face corrosion is desired.

The PGE Flange Gasket was designed to give operators an alternative to ailure-prone phenolic-based insulating gaskets. Based on its construction, the PGE will provide a superior, long-lasting solution when compared to phenolic-based designs. The PGE is available in two configurations: full-face (Type E) and ring style (Type F). Depending upon the sealing element selected, the PGE is rated for most all hydrocarbon and water service applications.

The unique design of the Pikotek PGE gasket 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 Teflon lip seals. As a result of this advanced gasket design, maintenance-free flange isolation and flange face corrosion mitigation are achieved economically.

The Pikotek VCS Flange Gasket is a "Very Critical Service" gasket designed for electrical flange insulation and general sealing applications. This gasket is suitable for use in raised-face, flat-face and RTJ flanges in all pressure classes including API 15,000 psi service. In addition to its superior sealing characteristics and excellent dielectric properties, the VCS gasket is ideal for isolating flanges made from dissimilar metals (thus mitigating galvanic corrosion) and for mitigating localized flange face corrosion.

The VCS was originally designed to provide a reliable sealing solution for electrical insulation of critical flanges, particularly where phenolic ring gaskets had been failing in RTJ flanges. The gasket was successfully developed and tested by a major oil and gas company prior to initial service approval. After demonstrating the VCS to be superior to all competing products for sealing and insulating, the VCS was placed in operational service in 1981. Since then, hundreds of thousands of VCS gaskets have been placed into service throughout the world. Current users include virtually every international oil and gas company operating in every major worldwide market.
