GORE
Expanded PTFE (ePTFE) gaskets, sheet gasketing, form-in-place sealant, and packing — one material science across steel, glass-lined, and FRP flanges.
GORE makes expanded PTFE (ePTFE) gaskets, sheet gasketing, form-in-place joint sealant, and GFO packing. Style 800 Universal Pipe Gaskets seal steel, glass-lined, and FRP flanges in NPS 1/2 to 24 inch sizes, up to 315 C, and resist the cold flow that costs standard PTFE its bolt load. One gasket family can consolidate inventory.
What LibertyCES specifies from GORE
One gasket family seals reliably across steel, glass-lined, and FRP flanges — rated to ±600°F. Consolidates inventory instead of stocking multiple gasket types.
Compresses to fill flange irregularities — for emergency repairs and large-diameter applications where a stamped gasket won't seat correctly.
Field-cuttable ePTFE sheet for custom gasket fabrication when a standard ring doesn't fit.

Frequently Asked Questions
What is the difference between PTFE and expanded PTFE (ePTFE) gaskets?
Standard PTFE is prone to "cold flow" and loses bolt load over time. Expanded PTFE resists creep and maintains bolt load integrity, which is why GORE gaskets outperform conventional gasket materials in chemical flange service.
Can one GORE gasket replace multiple gasket materials in a plant?
Yes — GORE Style 800 Universal Pipe Gaskets seal reliably across steel, glass-lined, and FRP flanges, consolidating inventory instead of stocking multiple compatible-but-different gasket types.
What temperature range do GORE gaskets handle?
Up to ±600°F, covering the majority of industrial chemical process flange applications.
Are GORE gaskets used in semiconductor manufacturing?
Yes — GORE lists semiconductor manufacturing directly among the named industries for its ePTFE gasket line, alongside chemical processing, pulp & paper, mining, and power generation. See LibertyCES's semiconductor & high-purity manufacturing page for the full manufacturer cluster.
