Over time, and for any number of reasons, flanges are prone to surface deviations. Damaged areas will tend to create a leak path that the gasket must try to seal.
Flange damage most commonly occurs when removing previously used gasket material from the sealing surface – tools such as chisels, or screw drivers, should be avoided. A brass wire brush is suggested.
The video below proves how well GORE® Gasket Tape Series 500 works on flanges with surface deviations versus a standard filled PTFE gasket.

GORE® Universal Pipe Gasket (Style 800) provides a reliable seal for steel, glass-lined steel and fiber reinforced plastic (FRP) flanges, in the full spectrum of strong acid, alkali, and solvent process media, including the most challenging thermal cycling and elevated temperature applications.
This single gasket solution can reduce the process safety and production downtime risks caused by the use of an incorrect gasket material. Highly conformable 100% ePTFE reliably seals irregular surfaces.
What Makes the GORE Universal Pipe Gasket Unique?
- Proprietary, patented technology. GORE Universal Pipe Gasket (Style 800) uniquely combines two patented construction elements, each made of 100% expanded PTFE (ePTFE).
- A non-permeable barrier layer covers the inside diameter and gasket flange faces, creating a tight seal at low gasket stress.
- A conformable-yet-strong interior provides superior resistance to creep and cold flow.
Long-Term Reliable Sealing
Unlike conventional (filled and skived) PTFE, expanded PTFE (ePTFE) gaskets are highly conformable to common flange imperfections, creating a tight seal in challenging conditions.
With superior resistance to creep and cold flow, GORE Universal Pipe Gasket (Style 800) retains its dimensional stability through thermal and pressure cycles. Bolt load is maintained, to achieve a long-term reliable seal.
One Gasket, Many Applications
The patented technologies of GORE Universal Pipe Gasket (Style 800) deliver a low stress-to-seal capability that is ideally suited for glass-lined steel and FRP piping systems, while maintaining the material strength required for outstanding performance in steel systems.
Chemically-inert GORE Universal Pipe Gasket (Style 800) provides a highly effective seal for strong alkali-, acid- and solvent-based chemical process systems. Made of 100% ePTFE, it is resistant to all media (pH 0-14) except molten/dissolved alkali metals and elemental fluorine.
GORE Universal Pipe Gasket (Style 800) creates a tight, reliable seal for multiple flange materials, so it can replace multiple other gasketing materials. By streamlining gasket ordering and inventories and standardizing the gasket selection and installation process, using GORE Universal Pipe Gasket (Style 800) across multiple pipe flange materials and process media reduces the process safety and production downtime risks from the use of an incorrect gasket material.
