What is asbestos gasket sheet?
Asbestos gasket sheets Asbestos gasket sheet is a tough and fibrous material that offers superb resistance to volatile chemicals and extremes of temperature – but it’s a particularly hazardous material to work in close proximity to.
What is a Garlock gasket?
Garlock® high temperature gasketing excels in the harshest conditions—intense heat and high pressure. These high performance gasket materials have been laboratory tested for fire safety. Style 4122 cut gaskets and sheet provide resistance to extreme temperatures, oxidation, corrosion and chemicals.
What material is used for exhaust gasket?
Exhaust manifold gaskets may be made of embossed steel, sometimes in multiple layers. These gaskets may also be made of high-temperature fibre material, graphite, and ceramic composites, among others. Some gaskets use a combination of different materials.
Where are asbestos gaskets used?
Parts sealed with asbestos gaskets include pipes, pumps, compressors, valves, boilers, engine cylinder heads, heat exchangers and condensers.
What is EPDM rubber gasket?
EPDM stands for Ethylene Propylene Diene Monomer, a synthetic rubber used in a range of applications. EPDM is used most commonly used in the automotive and construction industries for various seals due to its excellent resistance to environmental factors such as Ozone, UV and general weathering.
Do Garlock gaskets contain asbestos?
In 2009, a Philadelphia jury awarded $17 million to the families of two men who claimed they developed mesothelioma as a result of working with asbestos products made by Garlock and Crane Co. Evidence presented revealed that Garlock’s gaskets contained 75% to 90% asbestos.
