Fiber-Based Gaskets
Important: If you have any uncertainties about what material to use, just call us! We have employees that have been selling gaskets and servicing gasket applications for decades. We have sold gaskets in over 100 different materials! What follows below are generalizations for different categories of gasket materials. Use the information below only as a general guideline, and not as advice for your specific application.
Fiber-Based Gaskets: Strands of fibers (often aramid fibers) combined with assorted binders, are compressed to create the raw material for fiber-based gaskets. Gaskets from these materials are generally able to withstand higher temperatures than their rubber and synthetic rubber brethren. Gaskets cut from these compressed sheets, offer improved torque retention. This means that the initial load on the bolt that is compressing the gasket is better retained. Without this retained compression, the gasket may lose its sealing capability. Fiber-based gaskets also tend to have improved resistance to oils and hydrocarbons making them a solid choice for many industrial applications.
