GORE® Gasket Tape Series 1000 for Glass Lined Steel Flanges
Easily and reliably seal glass-lined steel to contain aggressive media, protect equipment, and reduce emissions.
Reliable sealing for glass-lined steel piping and equipment
Chemical processors use glass-lined steel pipe and equipment to deal with aggressive media under demanding conditions. Yet the inherent demands of such systems can make it challenging to maintain a tight, lasting seal and prevent leaks that can pose hazards to the equipment, and to the working environment. GORE® Gasket Tape Series 1000 addresses these challenges:
- High temperatures
- Alternating system pressures
- Limited gasket loads
- Deviations in flanges / sealing surfaces
Expanded PTFE Tape
Made of 100% expanded PTFE (ePTFE), GORE Gasket Tape 1000 is a highly conformable sealant tape is chemically inert, and highly resistant to creep, cold flow and clamp-force loss. Its proprietary barrier core maintains an extra-tight seal even at low loads.
A Higher Performance Industrial Sealing Product
GORE® Gasket Tape 1000 contains aggressive media, protects glass-lined steel equipment and reduces emissions.
Unique Barrier Core Technology
- Barrier core engineered to amplify the available load.
- Seals more than 10 times tighter than other ePTFE gasket tapes. (Especially important where glass-lined reactor safety is a consideration.)
Outstanding Conformability to Deviations
- Seals deviations even at low gasket stress
- Easily passes the bubble test, for trouble-free mechanical completion (MC) or start-up
Optimal Form for Easy Handling
- Gasket can be customized on-site
- No fabrication lead-time required
- Convenient spool format simplifies and speeds handling & transport
- Adhesive backing enables easy installation in ambient temperatures from 2–50 °C (36–122 °F)
- Faster, less complicated shimming tape technique for larger deviations
- Reduces inventory costs
Reliable and Long-Term Seal
- Barrier core creates a tight seal that impedes even highly permeating media
- Provides chemical protection across the full flange width (100% ePTFE)
- Tape is engineered to resist creep and clamp-force loss
- Allows full use of the specification range of glass-lined steel equipment
- Enables longer maintenance cycles, as demanded by leading chemical producers
Applications for GORE Gasket Tape Series 1000
GORE Gasket Tape Series 1000 offers the performance and versatility to reliably seal a range of industrial glass-lined equipment, in diverse applications with harsh process conditions.
- Processes that use highly aggressive media, for example, in the chemical processing or mining and minerals industries.
- Any glass-lined columns, mixer vessels, or reactor, storage and receiver tanks with glass-lined steel flanges that are large (≥ DN600/ASME 24”) or non-standard.
GORE® Gasket Tape Series 1000 addresses all the challenges of reliably sealing large glass-lined steel flanges.
Comparison with Competitive Products
Aggressive media can cause common envelope gaskets to degrade or fail, creating risks for personnel and potential for equipment/corrosion damage, production downtime and related costs.

Certificates & Application Information
| Type | Description | File |
|---|---|---|
| TA Luft | For the TA Luft1 test, the seal is installed in a DN40/PN40 steel flange, usually with a gasket stress of 30 MPa. The flange is then exposed to a defined temperature for minimum 48 hours. After cool down, leakage rate is measured over a period of at least 24 hours. The test pressure is 1 bar helium. TA Luft certificates are available for thicknesses 6 mm. 1Federal Ministry of Germany for the Environment, Nature Conservation, Building and Nuclear Safety: First General Administrative Regulation Pertaining the Federal Emission Control Act (Technical Instructions on Air Quality Control - TA Luft), Joint Ministerial Gazette, July 30, 2012. | Download PDF |
