GORE® Universal Pipe Gasket (Style 800)

For All Standard Flanges

GORE® Universal Pipe Gaskets (Style 800) are used to seal all types of flanges in chemical process piping. Designed to meet the needs of many different piping materials, they are ideal for standardizing gasket material across steel, glass-lined steel, and FRP systems, whenever a non-metallic gasket can be used.

Unaffected by even the most aggressive chemicals, Style 800 gaskets combine all the properties of expanded PTFE with exceptional sealability. Engineered to deliver superior bolt load retention, these gaskets exhibit exceptional creep resistance for reliable sealing of steel piping flanges. And due to their unique design, they provide the lowest stress-to-seal for applications in the most fragile plastic and glass-lined flanges.

Look to GORE® Universal Pipe Gaskets for exceptional perfor- mance in three important areas: conforming to irregular surfaces, helping to protect flanges, and seal reliability. With over 30 years of manufacturing and technical experience, depend on Gore gaskets when you need the highest level of confidence.

Most Reliable Seal
GORE® Universal Pipe Gaskets (Style 800) deliver higher sealing reliability than other PTFE-based gaskets. These gaskets have exceptional bolt load retention and creep resistance character- istics, as demonstrated in HALR (High Temperature Aged Load Relaxation) testing.

Standardize Piping System Gaskets
When considering the parameters of temperature and pressure, Style 800 gaskets offer the largest operating zone, thus allowing use across virtually all chemical process piping systems. The vast majority of processes run at less than 450ºF and 1,000 psi internal pressure. This gasket operates up to 600ºF and up to 3,000 psi.

The lower bolt loads needed to seal with the GORE® Universal Pipe Gasket will support standardization of non-metallic gasket materials in steel, FRP, and glass-lined steel flanges.

Blowout Safety
The GORE® Universal Pipe Gasket delivers improved creep relaxation and higher tensile strength, which makes the gaskets more resistant to blowout. In Hot Blowout testing (HOBT), when compared to a leading filled PTFE material, the GORE® Universal Pipe Gasket showed superior results. Tested in accordance with HOBT1 and HOBT2 procedures, blowout of the filled PTFE material occurred when the internal pressure reached 1,900 psi at 450ºF. GORE® Universal Pipe Gaskets did not experience blowout at 450ºF and 2,900 psi during the tests; thus the temperature was increased with pressure maintained until blowout did occur at 682ºF. The significantly higher blowout resistance of the GORE® Universal Pipe Gasket is a result of the improved tensile and mechanical properties achieved with the new technology.

Clean the flange faces and apply the gasket. Tighten to the manu- facturer's recommended torque load for the piping system. Torque tables and installation procedures are available on request.
