1mm Thick 10pcs Hard PTFE Flat Washer Gasket, ID 3-100mm, Temperature Resistant for Flange Applications,IDxODxCS,4x9x1mm

Operating temperature range: -200°C to 260°C (-300°F to 500°F), suitable for alternating high and low temperatures or continuous high temperature conditions. Advantages: Made of polytetrafluoroethylene (PTFE), finely crafted, with excellent corrosion resistance, good self-lubricating properties, good insulation, non-conductive, and resistance to high and low temperatures. Gaskets can provide a bearing surface for fasteners, distribute loads, or be used as gaskets between components. Under moderate compression, they can form a reliable seal and maintain long-term shape memory, mitigating stress relaxation and reducing the need for repeated tightening. Widely used in flange seals, electrical insulation materials, linings in contact with corrosive media, slider supports, guide rail seals, and lubrication materials in chemical, metallurgical, machinery, electronics, electrical, and construction industries.
