Inorganic Fiber Gasketing Style 5500

Inorganic fibers with a nitrile binder

Garlock® Inorganic Fiber Gasketing offers excellent thermal stability with minimal weight loss, reduced creep relaxation and improved torque retention. The inorganic fibers have excellent thermal and oxidation resistance, withstanding a continuous operating temperature of up to 550° F (290° C), and maximum spike of 800° F (425° C).
