Square seal for Terex RT-130

The 208402 square seal functions as a static or dynamic sealing element within the hydraulic and transmission assemblies of heavy machinery. Its primary purpose is to contain hydraulic oil or lubricants and prevent fluid migration between mating surfaces. The square cross-section provides a distinct contact surface area compared to standard round seals, which assists in maintaining system pressure and preventing fluid loss during operation. This component is essential for the integrity of hydraulic circuits, ensuring that cylinders and valves function within their designed parameters.

This part is specifically utilized in Terex RT-130, T300, and T340-1XL crane models. It is installed in areas where a secure seal is required to withstand the operating pressures of the crane hydraulic system. Proper installation of this seal helps maintain the overall performance of the machine by preventing pressure drops and fluid leaks that can occur in high-pressure environments. Regular inspection and replacement of such seals are standard procedures in the maintenance of these crane systems to ensure continued operational efficiency.
