Expanded graphite gaskets provide excellent chemical resistance and thermal stability, but they come with notable limitations. They exhibit relatively low mechanical strength, making them prone to cracking or extrusion under high loads and pressure surges. In oxidizing environments, graphite begins to degrade at sustained temperatures above 450°C. The material can also adhere strongly to flange surfaces, making removal difficult and potentially damaging gasket seating areas. Creep relaxation over time may require frequent retorquing, and their brittleness demands careful handling during installation. They are not ideal for strong oxidizers or certain acidic conditions that attack graphite.

Ring joint gaskets are primarily used in high-pressure, high-temperature flange connections across the oil and gas, petrochemical, and power generation industries. Their common applications include wellhead assemblies, pipeline flanges, valves, pressure vessels, and heat exchangers, where they provide reliable sealing under extreme conditions.

Double jacket gaskets are sealing components featuring a metal outer shell filled with a soft, non-metallic material. They work by compressing between flange faces, allowing the filler to conform to surface irregularities and create a tight seal, while the metal jacket provides strength, blowout resistance, and durability under high pressure and temperature conditions.

PTFE gaskets provide outstanding chemical resistance, wide temperature tolerance, low friction, and reliable sealing, making them suitable for harsh and high-purity environments.
