O-ring 130x5 for Terex machinery

The 00020998 O-ring serves as a critical sealing component within Terex heavy equipment, designed to maintain a tight seal between mating surfaces. By preventing the escape of hydraulic fluids, oils, or air, it ensures the integrity of pressurized systems and protects internal assemblies from external contaminants. The component is manufactured from Nitrile Butadiene rubber with a hardness rating of 80 Shore A, providing resistance to common industrial fluids and pressure-induced extrusion.

This specific O-ring measures 130 mm in inner diameter with a 5 mm cross-sectional thickness. It is utilized across a wide range of Terex machinery, including cranes and dumpers, where it is commonly found in pipe connections, reservoir covers, pump housings, and valve assemblies. Proper installation of this seal is necessary to prevent fluid loss, maintain system pressure, and avoid potential damage to major machine components caused by leaks or contamination.

O-rings function as static or dynamic seals in hydraulic, pneumatic, and transmission systems. When placed in a groove, the ring is compressed to create a barrier that blocks fluid paths. Over time, seals may harden or crack due to environmental exposure or mechanical stress, requiring periodic inspection and replacement to ensure the continued operation of the equipment's fluid systems.
