Ingersoll-Rand 47685787001 O-Ring for Air Compressor Parts

An O-Ring is a torus (doughnut-shaped) mechanical seal designed to be seated in a groove and compressed between two or more parts, creating a barrier at the interface. This simple yet highly effective component prevents the leakage of fluids (liquids or gases) and the ingress of contaminants under a wide range of pressures and temperatures.

• Fluid Sealing: Preventing the internal leakage of hydraulic fluid, fuel, water, air, or other gases and liquids.
• Contaminant Exclusion: Blocking external contaminants like dirt, dust, and moisture from entering a system.
• Pressure Retention: Maintaining system pressure by sealing the clearance between mating components.
• Vibration Dampening: Acting as a cushion in some applications to absorb minor vibrations.

1. Installation: The O-Ring is placed in a gland (a specially designed groove).
2. Compression (Sealing Force): As the mating parts are assembled, the O-Ring is compressed, deforming its cross-section.
3. System Pressure Activation: When system pressure is applied, it forces the O-Ring to deform further into microscopic clearances.
4. Self-Energizing Seal: Pressure-enhanced deformation increases sealing force, making it effective even at very high pressures.
