Hidroil washer for Link-Belt LS418

The Hidroil washer, part number HR 0589, functions as a sealing component within the hydraulic circuits of Link-Belt machinery. It integrates a metal outer ring with an inner elastomeric sealing element to create a tight seal around bolts or fittings, effectively containing hydraulic fluid and preventing external contaminants from entering the system at critical connection points.

This component is compatible with the Link-Belt LS418 crane. It is specifically engineered to meet the structural and sealing requirements of the hydraulic assemblies on this model. The washer ensures that bolted joints remain secure while maintaining the integrity of the hydraulic lines under operational pressure.

Hidroil washers are commonly used in hydraulic systems to seal threaded connections where fluid pressure is present. The metal ring provides the necessary structural support for fastener torque, while the elastomeric insert compresses to form a barrier against leaks. By maintaining a proper seal, these washers help preserve system pressure and protect internal hydraulic components from the ingress of moisture or debris.
