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.
