On this page, you can purchase non-asbestos jointing gaskets with a thickness ranging from 0.5mm to 5mm. As a general rule, it’s wise to pick the thinnest material that fits your specific application needs. This not only helps save costs but also has the potential to boost your equipment’s overall performance.
General Properties of Non-Asbestos Jointing Gasket Sheet
Non-asbestos jointing gaskets are made by compressing aramid fiber and nitrile butadiene rubber (NBR), giving them excellent oil resistance. They’re also well-suited for scenarios where they might come into contact with substances like water, gasoline, or natural gas.
Thanks to these properties, non-asbestos jointing gaskets are widely used in various fields. You’ll often find them in air compressors, diesel engines, and pipelines, and they work well in a wide range of general industrial and marine environments.
Product Information
The gasket is made from a blend of aramid fiber, non-asbestos mineral fiber, synthetic fiber, and synthetic oil-resistant rubber. Its manufacturing process includes hot-roller compression followed by vulcanization, which guarantees high quality and long-lasting performance.
The following table summarizes the general properties and suitable application media:
