Filler material: Specially treated PILLARFOIL™
Spiral wound gasket with a specially treated flexible graphite tape filler. It ensures sufficient sealability even at low tightening pressure.
This gasket is effective in preventing small leaks of gasified mediums such as LPG, and fluids for which tight sealing is required.
This gasket can be used as a countermeasure to sealability loss in piping caused by external forces (vibration, uneven tightening, temperature/pressure fluctuations, etc.) that are difficult to absorb with conventional sheet gaskets, without changing flanges, bolt materials, etc.
