Ceramic gaskets excel at extreme temperatures (up to ~1,430°C) and fireproofing, ideal for kilns and heavy industry. Heat-resistant rubber gaskets (silicone/EPDM/NBR) offer elasticity and easy installation for moderate temperatures (up to ~350°C). Graphite gaskets balance high-temperature and high-pressure performance (approx. 400–850°C) with good chemical resistance, commonly used in valves and flanges. Choose by operating temperature, pressure, chemical exposure, and required elasticity.
