Gaskets cut from sheet packing were used in a variety of industrial settings. Sheet packing was used in engine parts and other mechanical applications to resist the effects of steam, high pressure, water, oil and other chemicals. Chrysotile asbestos was traditionally used in the product, but in acidic environments some crocidolite was also used to prevent erosion. Gasket material and heat seals made from asbestos sheet packing were used in mechanical systems that involved the transport of gases, hot oils, steam, chemicals, grease or acid. Uses for these products include:
Product Description
Sheet packing was a common asbestos – containing product used to make gaskets for commercial and industrial settings. Asbestos fibers are mixed with a binding material and compressed to form the product, which can then be cut into various shapes and sizes to form gaskets and heat seals.
These products were used on pipes and boilers and in between joints on ships. When used in between pipe joints as a gasket, sheet packing prevents the contents of the pipe from leaking out.
Asbestos was commonly used as a component of this product because it provided resistance to high temperatures, as well as excellent durability and flexibility. Its cost effective nature also made asbestos an appealing material to produce gaskets and heat seals cheaply.
