An O-Ring Seal is a versatile and widely used sealing solution found in both static and dynamic applications. It features a simple doughnut-shaped profile that compresses between two surfaces to create a tight barrier. When installed in a groove and compressed, the O-ring deforms to fill the gap between the mating parts, preventing internal fluid or gas from leaking and external contaminants from entering.Attributes:• Creates a leak-proof seal in joints between two or more components.• Maintains sealing performance under pressure, vibration, and movement.• Functions in both static (fixed) and dynamic (moving) setups.Applications: An O-Ring Seal is used on the air-line adapter spool to prevent air leaks and protect more expensive parts from leaks and contamination.
