Expanded graphite gaskets are designed for high-temperature applications, often withstanding continuous heat up to 500°C and even higher in non-oxidizing environments, thanks to the natural thermal stability and resilience of graphite.

Ring joint gaskets are designed for high-integrity sealing in extreme conditions and can typically withstand pressure ratings up to 2,500 class per ASME B16.5, with specialized API 6A types handling service pressures beyond 20,000 psi.

This article examines whether double jacket gaskets demand a specific flange surface finish, discussing the influence of surface roughness on sealing reliability and relevant industry guidelines.

PTFE gaskets provide reliable sealing in applications requiring high chemical resistance, low friction, and temperature stability. They are widely used in chemical processing, food and pharmaceutical industries, and any system handling aggressive fluids or demanding non-contamination.

The serration profile on a flange surface plays a critical role in the sealing performance of gaskets by influencing contact stress distribution, leakage paths, and the gasket's ability to conform to surface irregularities. This article examines how different serration geometries—such as depth, pitch, and shape—affect sealing integrity under various operating conditions.

Non-asbestos gaskets are made from a combination of synthetic fibers such as aramid, mineral fibers, carbon, graphite, PTFE, and elastomeric binders, offering safe and durable sealing without the health risks of asbestos.
