• Specification

• Key Roles in Hydraulic Systems

1.Leak Prevention: Seals the gap between the hydraulic cylinder rod and cylinder head, stopping expensive hydraulic oil from leaking—this avoids oil waste and prevents environmental contamination (e.g., oil spills on job sites).

2.Contaminant Blocking: The integrated wiper seal (part of the packing set) scrapes dust, gravel, and moisture off the cylinder rod as it extends/retracts, preventing abrasive particles from entering the cylinder and causing wear to the rod or piston.

3.Pressure Retention: Withstands high hydraulic pressure during heavy lifting or digging operations. The PTFE backup rings prevent the main seals from "extruding" (deforming into gaps) under pressure, ensuring consistent sealing performance.
