Semi-Metallic GasketsExtreme Temperature Gasket (XTG)
Lamons Extreme Temperature Gasket (XTG) is the next evolution in high-temperature sealing, pushing the limits of performance and reliability. Building on the trusted HTG design, XTG raises the temperature resistance from 1500°F (815°C) to 1800°F (982°C), setting a new industry benchmark. Engineered with super-oxidation-inhibited flexible graphite and advanced vermiculite barriers, it offers superior oxidation resistance while maintaining integrity in the harshest conditions. Certified through the rigorous Firesafe API 6FB test, XTG ensures safety in critical applications like reactors, cracker units, and flares in petrochemical and power generation facilities. With seamless compatibility for existing HTG users, strategic pricing flexibility, and 24/7 in-house engineering support, Lamons XTG delivers unmatched durability, safety, and performance—engineered for extremes, certified for safety.
