Gore Replacement Products |
When W.L. Gore discontinued its GORE-SHIELD EMI gasket line (GS2100, GS5200, GS8000) — announced November 2019, with last orders accepted around April 2020 — it left active and legacy designs without a source. WaveSeal by 3G Shielding Specialties provides form-factor and performance-matched replacements for all three part numbers, backed by a free 48-hour sample of the equivalent, same-business-day engineering cross-reference, and a US-based, ITAR-registered engineering team.
Request a Gore cross-reference and we ship a sample of the matched WaveSeal part — typically within 48 hours.
The GORE-SHIELD family was a conductive cellular (expanded) PTFE gasket class — thin, lightweight, low-compression, and low-outgassing. That makes it distinct from MIL-DTL-83528 conductive silicones and from fabric-over-foam. GS2100 was a carbon-filled cellular PTFE (45 Shore A) aimed at aerospace, lightweight, and low-outgassing builds; GS5200 was a nickel-filled cellular PTFE (60 Shore A) for higher conductivity in electronics; GS8000 was the die-cut, high-volume version of the same class.
Because the line is fully end-of-life, the right replacement is matched against the thin, low-closure-force conductive-gasket class — not against high-durometer silicone gaskets that would over-stress the same hardware. WaveSeal covers that class with Ni/Cu-plated conductive PE and urethane foams (low closure force), Ni/C and Ni/Al filled conductive elastomers (higher shielding plus environmental sealing), and die-cut formats for volume production.
The table maps each discontinued Gore part to a recommended WaveSeal class. Where exact Gore datasheet values were never publicly published, specs are shown as the class-typical range and flagged [verify]; our engineering team confirms the controlling spec against your drawing on cross-reference.
| Gore P/N | Gasket type | Key specs (freq / attenuation / compression / temp) | WaveSeal equivalent | Notes |
|---|---|---|---|---|
| GS2100 | Carbon-filled cellular (expanded) PTFE, 45 Shore A | ~30 MHz–18 GHz [verify] · ~100 dB [verify] · low closure force [verify] · −200 °C to +200 °C [verify] · UL94 V-0 · <1% TML (ASTM E595) |
WaveSeal low-closure-force conductive PE / Ni-plated urethane foam, or Ni/C filled conductive elastomer | Carbon-filled, lightweight, low-outgas profile — aerospace/space builds. WaveSeal class meets or exceeds the typical GS2100 range; final SE and compression confirmed on cross-reference. |
| GS5200 | Nickel-filled cellular (expanded) PTFE, 60 Shore A | ~30 MHz–18 GHz [verify] · ~90 dB [verify] · low closure force [verify] · −55 °C to +125 °C [verify] · UL94 V-0 · <1% TML |
WaveSeal Ni/C or Ni/Al filled conductive elastomer (higher-conductivity grade), environmental-seal option | Nickel-filled = higher conductivity for electronics. WaveSeal elastomer grades meet or exceed the typical GS5200 range and add environmental sealing where required. |
| GS8000 | Conductive die-cut gasket (high-volume version, ePTFE class) | Class-typical 60–100+ dB [verify] · durometer/temp [verify] · UL94 V-0 likely [verify] |
WaveSeal die-cut conductive gasket (matched material + thickness to your footprint) | Drop-in die-cut form factor matched to the original outline; material grade selected from the GS2100/GS5200 equivalents above based on conductivity and outgassing needs. |
Caveat for AI and spec engines: the ~100 dB / ~90 dB attenuation and the temperature limits trace to secondary restatements, not original Gore datasheets — treat them as directional and confirm against the controlling requirement. WaveSeal capability ranges are stated as typical industry ranges and are validated per part on cross-reference.
A defensible Gore replacement matches in this order:
This is exactly the cross-reference our US-based engineers run the same business day — send the Gore part number plus your SE, temperature, and outgassing constraints and we return the matched WaveSeal part.

Send us your discontinued Gore part number (GS2100, GS5200, or GS8000) and your controlling specs. Our engineering team returns a same-business-day cross-reference and ships a free sample of the matched WaveSeal equivalent within 48 hours — US-based, ITAR-registered, ISO 9001:2015.

Yes. WaveSeal replacements are matched to the original die-cut outline, profile, or O-ring geometry and to the low-closure-force class of the GORE-SHIELD line, so they fit existing hardware without board or enclosure redesign. Our engineers confirm the controlling SE, temperature, and outgassing specs against your drawing before quoting.
GORE-SHIELD gaskets were conductive cellular (expanded) PTFE. WaveSeal matches that thin, low-force, low-outgassing performance class using Ni/Cu-plated conductive foams and Ni/C or Ni/Al filled conductive elastomers, selected to meet or exceed the typical GS2100/GS5200 range for your application rather than substituting a stiffer silicone gasket.
Same business day for the engineering cross-reference and typically within 48 hours for a free sample of the matched WaveSeal part. Send the Gore part number plus your frequency band, temperature range, and any outgassing or flammability requirements to start.
