Kalrez and Aflas O-rings are both high-performance sealing components known for their exceptional chemical resistance, particularly in harsh environments, but differ in their specific strengths with Kalrez offering wider chemical compatibility across a broader temperature range, while Aflas excels in steam and base resistance, typically at a lower cost point; both are considered superior to standard elastomers like Viton in extreme applications.

High-Performance Sealing Solutions

Standard elastomer FEP-O-rings often suffer from chemical degradation when exposed to aggressive media or atmospheric gases, resulting in seal failure, hardening, or embrittlement. This is typically due to inadequate solvent resistance and restricted working temperature ranges.

In contrast, our encapsulated FEP-O-rings feature a seamless fluoropolymer jacket that prevents direct contact between the inner core and the process medium. The superior resin properties of the FEP jacket provide universal chemical resistance, making these seals suitable for the most demanding industrial applications and high-temperature environments.

High-Performance Sealing Solutions

Traditional elastomer O-rings, such as standard Nitrile or Viton, often face chemical degradation when exposed to aggressive solvents, acids, or atmospheric gases. This leads to hardening, swelling, or embrittlement—eventually resulting in seal failure. In contrast, our FEP Encapsulated O-Rings are designed for the most demanding industrial environments. By combining a seamless Fluorinated Ethylene Propylene (FEP) jacket with a high-rebound rubber core, these seals provide: Universal Chemical Resistance: The FEP shield is chemically inert to almost all industrial chemicals. Superior Thermal Range: Maintains integrity in high-temperature environments where standard seals fail. Low Friction: The self-lubricating nature of the fluoropolymer jacket reduces "stick-slip" and wear. Static Reliability: Ideal for pressure vessels, heat exchangers, and chemical pumps.
