SEALGO® PEI Insulation Gasket is specially designed for highly corrosive service conditions. A PTFE bushing is installed inside the gasket; the outstanding corrosion resistance of PTFE makes it suitable for most chemical media. Meanwhile, a metal seal ring is built into the PTFE bushing, enabling the gasket to adapt to high-pressure service and cover a pressure range of 150LB~2500LB.
Equipped with a spring-energized seal (SES), this gasket delivers excellent performance under cyclic pressure conditions. The Insulation substrate can be selected from G10, G11 or G7 based on service temperatures, with a total gasket thickness of 6mm.
SEALGO® PEI Insulation Gasket is an economical alternative to SEALGO® SEI special alloy Insulation gaskets, featuring broader temperature adaptability and a maximum manufacturing diameter of Φ1500mm.
