PTFE Gaskets

High-purity fluoropolymer gaskets engineered for aggressive chemical service, wide temperature ranges, and hygiene-critical applications.

what it does

Chemically Inert Sealing for Critical Media

PTFE gaskets deliver reliable flange sealing where chemical resistance, purity, and thermal stability are non-negotiable across corrosive, hygienic, and high-temperature services.

CoRE FEATURES

Designed for Chemical & Hygiene Applications

Exceptional Chemical Resistance

Unaffected by most acids, alkalis, solvents, and aggressive process media.

FDA & Hygienic Compliance

Approved for food, pharmaceutical, and oxygen service.

Low Creep, Stable Sealing

Modified PTFE reduces cold flow while maintaining sealing integrity.

Wide Operating Temperature Range

Performs reliably from cryogenic conditions up to approximately +260°C.

Product information

Configured for Chemical Performance

Engineered for aggressive media, wide temperature ranges, and purity-critical systems, ensuring reliable sealing across demanding industrial applications.

Types

Virgin PTFE

Pure, unfilled PTFE offering maximum chemical resistance and electrical insulation.

Expanded PTFE (ePTFE)

Microporous structure improves conformability and sealing on irregular flange surfaces.

PTFE Enveloped Gaskets

Composite construction combining a resilient core with a PTFE envelope for chemical resistance and mechanical strength.

RPTFE (Filled & Modified PTFE)

Glass, carbon, graphite, bronze, MoS₂, or polymer-filled PTFE for improved creep resistance, wear, and load-bearing capacity.
Benefits
01

Chemical Safe

Maintains sealing integrity across acids, caustics, solvents, and aggressive process media.

02

Thermal Stability

Performs reliably across extreme temperatures, supporting cryogenic and high-temperature use.

03

Low Friction

Non-stick surface minimizes adhesion while ensuring clean, contamination-free sealing in hygienic systems.

04

Service Durability

Resists corrosion, ageing, and environmental exposure for consistent long-term sealing performance.
