GORE® GR Sheet Gasketing
Exceptionally resistant to creep, cold flow and aggressive media, this 100% ePTFE gasket sheet reliably seals steel piping and equipment.

GORE® GR Sheet Gasketing is designed to outperform both conventional (filled and skived) PTFE and other ePTFE gasketing in steel piping and equipment.
GORE® GR Sheet Gasketing has the chemical resistance of conventional PTFE sheet gasketing without the creep and cold flow commonly associated with that material. GORE® GR Sheet Gasketing is stronger and more dimensionally stable than other ePTFE gaskets. It is highly conformable to rough or irregular sealing surfaces, and compresses into an extremely tough gasket that creates a tight, long-lasting seal.
GORE® GR Sheet Gasketing is a versatile, single-solution material for both standard and custom gasketing shapes and sizes.
What makes the GORE® GR Sheet Gasketing Unique?
Made of specially-engineered 100% expanded PTFE (ePTFE), Gore's patented manufacturing technology creates an ePTFE sheet with the highest degree of expansion available. Other ePTFE material has many un-expanded nodes. The increased expansion of GORE® GR Sheet Gasketing gives it superior tensile strength and dimensional stability, creating significant performance advantages in demanding applications.
GORE® GR Sheet Gasketing has greater tensile strength, so it retains greater dimensional stability in-use — in both thickness and width — than any other PTFE-based gasket, including any other ePTFE.
- Because its thickness remains more dimensionally stable than that of any other PTFE-based gasket, GORE® GR Sheet Gasketing maintains a greater percentage of bolt load in operation, providing a more reliable seal especially in thermal cycling and higher temperature conditions.
- The width of GORE® GR Sheet Gasketing also remains more dimensionally stable, avoiding gasket intrusion into the pipe bore which can negatively affect process performance.
- Along with providing a larger window for blowout safety, the dimensionally stable seal can also increase process uptime and reduce maintenance costs associated with gasket re-torque and replacement.
Crush-resistance tests show GORE® GR Sheet Gasketing excels at withstanding the extreme conditions of industrial flange sealing. It delivers a wider safety margin of seal reliability, both at installation and in operation at elevated temperatures.
Chemically inert GORE® GR Sheet Gasketing seals durably, whether in strong alkali-, acid- or solvent-based process systems. It resists all media (pH 0-14) except for molten/dissolved alkali metals and elemental fluorine.
The consistency and precision of Gore manufacturing processes give GORE® GR Sheet Gasketing a much more uniform distribution of mass than other ePTFE sheets. This promotes a more uniform and reliable seal.
Unlike skived or filled PTFE, GORE® GR Sheet Gasketing readily conforms to common flange imperfections. This can eliminate the need for flange resurfacing, expand the window of applicability and create a highly reliable initial seal, so start-ups can be more trouble free.
