Capped T-seal for Terex RT780

The capped T-seal, part number 217249, serves as a specialized hydraulic sealing component. Its design features a T-shaped profile intended to provide stability and resist extrusion when subjected to high pressure within hydraulic assemblies. The integrated cap provides support to the primary elastomer, assisting in the containment of hydraulic fluid in dynamic applications such as cylinders, valves, and other pressurized components of the machine.

This component is compatible with the Terex RT780 crane. It is engineered to maintain a hermetic seal within hydraulic systems, including boom, outrigger, and steering cylinders. The seal has a diameter of 6.00 inches. It is designed to function within the specific tolerances required by these systems to prevent fluid leakage and maintain operational pressure.

T-seals are typically utilized in hydraulic systems to prevent fluid bypass between moving parts. By providing a secure barrier, they help maintain the pressure necessary for the consistent operation of hydraulic actuators and control valves. The configuration of the seal and its backup rings is intended to manage the clearance gaps found in large-scale hydraulic equipment, ensuring that the sealing element remains in position during operation.
