GORE Universal Pipe Gasket (Style 800) provides a reliable seal for steel, glass-lined steel (GLS) and fiber-reinforced plastic (FRP) flanges. These Gore piping gaskets withstand the full spectrum of strong acid, alkali, and solvent process media, as well as the most challenging application conditions including thermal cycling and elevated temperatures. These highly conformable 100% ePTFE gaskets for flanges reliably seal irregular surfaces.

And, having a single pipeline gasket solution for multiple flange materials can reduce the chance of someone installing the wrong pipe flange gasket material — which could threaten process safety and risk production downtime.

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. This creates a tight seal at low gasket stress and protects the flange surfaces.

A conformable-yet-strong interior provides superior resistance to creep and cold flow.

Long-term reliable sealing

Unlike conventional (filled and skived) PTFE pipe gaskets, Gore’s expanded PTFE 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. This avoids gasket intrusion into the bore, and maintains bolt load, enabling a long-term reliable pipe seal.

Only GORE Universal Pipe Gasket (Style 800) offers this unique combination of chemical resistance and conformability. That’s why its performance as a pipe flange seal is unmatched by other gasketing materials.

• Chemically inert to virtually all acids, alkalis and solvents, except elemental fluorine and molten alkali metals.
• Highly conformable, to effectively seal even old, imperfect flange surfaces without the cost and downtime of re-surfacing.
• Creates a reliable seal that starts, and remains, leak-tight.

Our patented technologies deliver a low stress-to-seal capability that is ideally suited for glass-lined steel pipe and FRP piping systems, while maintaining the material strength required for outstanding performance in steel systems.

Using GORE Universal Pipe Gasket (Style 800) across multiple pipe flange materials and process media can:

• Streamline gasket ordering and inventories.
• Standardize gasket selection and installation processes.
• Reduce the risk of choosing the “wrong” pipe gasket material, which could create process safety and downtime issues.

In processes with elevated temperatures, GORE Universal Pipe Gasket (Style 800) is significantly more gas-tight than other non-metallic pipe flange seals.
