Ace Glass 7855-861 CAPFE O-Ring, Size 361

CAPFE - A "Rubbery" PTFE O-Ring

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.

CAPFE Advantages:

• Continuous encapsulation of thick, pure PTFE offers no seams or weak spots to break and leak.
• CAPFE offers both resilience and chemical resistance.
• Thick PTFE encapsulation permits wide application without leakage or deterioration.
• Resistant to all chemicals except molten alkali metals, hot fluorine and certain complex halogenated compounds.
• Extreme slipperiness of PTFE reduces friction in dynamic applications.
• CAPFE ranges from -60°C to +204°C, deterioration vacuum to 10,000 psi.

Features:

• Low friction
• High chemical resistance
• Low compression set compared to solid
• PTFE O-Rings
• Low gas and water vapor permeability compared to "flash" coated O-Rings
