Уплотнительное кольцо, 6,99 х 189,86 мм Caterpillar 9T4478

The Brake Cylinder Piston O Ring Seal maintains hydraulic pressure by preventing fluid from passing between moving surfaces during braking action. Proper sealing helps maintain steady pressure transfer, so braking response remains smooth and controlled during operation. It supports reliable force transmission from hydraulic fluid to braking components, helping maintain consistent performance over repeated braking cycles. Leakage prevention helps reduce pressure loss and supports efficient braking control under varying operating conditions.Attributes:• Prevents hydraulic fluid leakage during braking operation.• Maintains stable hydraulic pressure for consistent braking response.• Supports smooth pressure transfer during piston movement.Applications: The Brake Cylinder Piston O Ring Seal functions within hydraulic braking assemblies where pressure transfer is required for braking action. It supports controlled movement of hydraulic components and helps maintain a stable braking response.
