SEALMTL 80N FFKM O-Ring
Main Model for Mechanical Seals | Benchmarking DuPont KALREZ® CN800 | High Quality & Cost-Effective
Core Features
SEALMTL 80N is the main perfluoroelastomer (FFKM) O-ring for the mechanical seal industry. It is made of pure imported raw rubber, benchmarks DuPont KALREZ® CN800, and meets the ASTM D2000 perfluoroelastomer standard. The product has excellent performance stability in the temperature range of -10~230℃, wide chemical medium coverage, excellent processability, and high consistency in mass production. It is the preferred sealing material for non-amine medium working conditions below 230℃, combining high quality and cost-effectiveness, and has become the mainstream choice in the mechanical seal industry. |
