Product Features
  • 90 Shore A High-Durometer Material & Extrusion Resistance: Engineered with a high-hardness (90 Shore A) HNBR/FKM elastomer formulation providing exceptional extrusion resistance. Under dynamic hydraulic pressure spikes exceeding 35–42 MPa, it resists material nibbling and gap extrusion between metal coupling faces. 
  • Precision ORFS Groove Match & Zero-Leakage Face Sealing: Molded to tight dimensional tolerances specifically for ORFS (O-Ring Face Seal) female swivel ends and hose adapters. Achieves high axial compression upon coupling torque, filling micro-imperfections across mating surfaces for leak-free performance under intense machine vibration. 
  • Hydraulic Fluid Compatibility & Thermal Compression Set: Demonstrates superior chemical compatibility with CAT HYDO Advanced fluids, synthetic esters, and mineral oils, resisting swell and degradation. Features a low compression set profile across broad temperature swings (-40°C to +125°C), ensuring long-term elastic recovery.
