Ace Glass Inc 7855-872 O-Ring, Capfe, Size 125

Features:

• Sealing Performance
  • Continuous encapsulation of thick, pure PTFE offers no seams or weak spots to break and leak.
  • Thick PTFE encapsulation permits wide application without leakage.
  • Low compression set compared to solid PTFE O-Rings
  • Extreme slipperiness of PTFE reduces friction in dynamic applications.
• Chemical Resistance
  • CAPFE offers both resilience and chemical resistance.
  • Thick PTFE encapsulation permits wide application without deterioration.
  • Resistant to all chemicals except molten alkali metals, hot fluorine and certain complex halogenated compounds.
  • Low gas and water vapor permeability compared to "flash" coated O-Rings.
• Thermal Stability
  • CAPFE O-Rings range from -60°C to +204°C, deterioration vacuum to 10, 000 psi.

A totally different O-Ring having a resilient rubber core encased in a continuous, thick, non-porous FEP/PTFE encapsulation. This unique O-Ring solves the sealing problems where the chemical inertness of PTFE is a MUST and where maintenance-free dependability and long service life are required.
