Regarding fiber gasket F04
Thread Content
Hello, experts. Recently I came across the pipeline classification table for a well-known German company’s project, and the following gaskets were used for the utility media: Fibre gasket F04, Aramid fiber with nitrile binder. What kind of gaskets are these? Which category does it belong to again? I currently think it’s a PTFE-coated gasket, but I’m not entirely sure. I’d appreciate advice from those who know more about this. Thank you in advance
Hello! The so-called Fibre gasket F04, Aramid fiber with nitrile binder, refers to a fibrous gasket that contains aramid fibers and a nitrile rubber binder. This gasket is not a PTFE-coated gasket, but rather a fiber gasket. Aramid fibers provide strength and heat resistance, while nitrile rubber is used to enhance the sealing performance of the gasket. Such gaskets are commonly used in industrial pipelines and equipment to withstand high pressure and temperature conditions. .

Garlock BLUE-GARD, used for aramid gaskets at temperatures below 95 degrees.
The two parts of the sample have roughly the same problem. There are also pictures inside.
