Made-to-Order High-Temperature Graphite Gaskets
When you need a unique shape or size graphite gasket, we will precision cut one for you using your DXF file. This material, also known as Hochdruck, is graphite with stainless steel layers for added strength in hot environments.
First select a thickness, then select a sheet size that’s large enough to accommodate your gasket. Finally, send us your DXF file. Depending on the size of your gasket, we’ll send you as many same-design gaskets as a sheet will yield, up to 20 gaskets for 12"×12" sheets, and up to 40 gaskets for 24"×24" sheets.
