Quadring O-ring for Terex TX760B

The quadring, part number 6193403M1, is a specialized sealing component engineered for the rear axle brake system of the Terex TX760B backhoe loader. This component is specifically designed for machines configured with two-wheel steering. Unlike a standard O-ring, the quadring features a four-lobed cross-section, which increases the sealing surface area and helps prevent extrusion and twisting during operation. Its primary function is to create a tight seal that contains hydraulic brake fluid, ensuring that the necessary pressure is maintained for effective brake activation.

This component is compatible with the Terex TX760B model. It serves as a critical element in the hydraulic braking circuit, where consistent pressure is required for the machine to stop safely. By maintaining a seal within the brake assembly, the quadring prevents fluid loss and supports the overall functionality of the braking system. In hydraulic systems, quadrings are often utilized in dynamic applications where they provide a stable seal against reciprocating motion, effectively separating fluid chambers and preventing internal leakage within the axle assembly.
