Prevent the decrease in tightening force and the reduction of surface pressure due to flange deformation! Sheet-like gasket material with high swellability in oil.
The "AF2000" is a sheet-like gasket material made from special heat-resistant fibers, inorganic reinforcing materials, and synthetic rubber with oil swellability. Due to its high swellability in oil, it prevents the reduction of clamping force and the decrease in surface pressure caused by flange deformation, has a low stress relaxation rate, and is highly durable. It can be used in areas that seal lubricating oil and fuel. 【Features】 ■ High swellability in oil ■ Prevents reduction of clamping force and decrease in surface pressure due to flange deformation ■ Low stress relaxation rate and excellent durability ■ Standard operating temperature range is -40℃ to 200℃ ■ Standard operating surface pressure is 2MPa to 147MPa *For more details, please refer to the PDF document or feel free to contact us.
