Shut out infiltration and leakage! Improved heat resistance with grommet processing.
"MacGuard" is the name of an option that applies crimping processing of SUS316L or Hastelloy to the inner and outer diameters of gaskets. By adding MacGuard as an option for gaskets, it is possible to significantly improve sealing performance, contamination prevention, pressure resistance, heat resistance, and more. 【Features】 ■ Shuts out permeation leakage ■ Improved heat resistance ■ Blocks the occurrence of contamination ■ Protects the gasket from fluids ■ Significantly suppresses cold flow of fluorine-based gaskets ■ Prevents gasket adhesion ■ Greatly improves the handling of gaskets *For more details, please refer to the PDF document or feel free to contact us.
