TFE Encapsulated O-Rings and Gaskets are advanced sealing solutions designed for demanding industrial applications. Their key features include exceptional chemical resistance, wide temperature tolerance, and hygienic properties, making them ideal for pharmaceuticals, food processing, and chemical handling. The encapsulation of elastomeric cores (silicone or Viton) with FEP (fluorinated ethylene propylene) creates a robust barrier against aggressive chemicals while maintaining flexibility. These components are particularly valued in industries requiring contamination-free operations, such as cosmetics, pharmaceuticals, and bulk liquid transfer, due to their FDA compliance and USP Class VI approval.
Key Points Explained:
-
Superior Chemical Resistance
- The FEP encapsulation makes these teflon encapsulated gaskets inert to nearly all industrial chemicals and solvents, even under high temperatures and pressures.
- This property is critical for applications involving aggressive substances like mining slurries, agricultural chemicals, or pharmaceutical raw materials.
-
Dual-Material Construction
- Elastomeric Core: Provides resilience and compression for a tight seal (silicone for FDA-compliant applications, Viton for broader chemical resistance).
- FEP Encapsulation: A 0.020-inch virgin FEP layer meeting L-P-389A/ASTM-D-2116 standards, ensuring durability and non-reactivity.
-
Broad Temperature Range
- Operates from -75°F to +400°F (FEP/silicone) or -15°F to +400°F (FEP/Viton), accommodating extreme environments like cryogenic storage or high-temperature processing.
-
Low Friction & Nonstick Surface
- The smooth FEP exterior reduces insertion force and prevents material buildup, simplifying installation and cleanup in sanitary applications (e.g., food/beverage production).
-
Sanitary Design
- Eliminates contamination risks by preventing fluid absorption—unlike traditional elastomeric gaskets—making them ideal for pharmaceuticals and cosmetics (e.g., perfume/oil transfer).
-
Regulatory Compliance
- FDA-compliant and USP Class VI approved, ensuring safety for direct contact with consumables or medical products.
-
Industry-Specific Advantages
- Cosmetics: Safe for oils/fragrances.
- Paints/Dyes: Resists pigment adhesion.
- Brewing/Chemicals: Withstands corrosive liquids.
These features collectively make TFE Encapsulated O-Rings and Gaskets versatile, reliable seals for critical applications where chemical exposure, temperature extremes, or hygiene are paramount.
