GORE® Universal Pipe Gasket (Style 800) seals a broad range of flange materials with this low stress-to-seal, exceptionally dimensionally stable and chemically resistant 100% ePTFE gasket.

Universal Pipe Gasket (Style 800) Certification Oxygen Service BAM

The Federal Institute for Materials Research and Testing (BAM) tests the sealing material compatibility for use in flanged connections with liquid and gaseous oxygen. Further information on the test procedure and the result can be found in the following test report. Please note that the test was conducted on the version of this product with no printing ink product identification.

CAUTION: Extra care is advised to ensure that the gasket surface is free from particulate contamination that accumulates due to static charge.
