Since they are sealed with O-rings, they prevent oil leakage better than the conventional connectors of taper seal type.FFOR (Flat Face O- Ring) system is ISO compliant for high pressureFFOR Class B selected by design team to best retain o-rings at assy. PREVPREVNEXTNEXTFIRSTFIRSTLASTLASTEXITEXITMENUMENURELIABILITY AND DURABILITY FEATURES [NO.10]LONG LIFE HOSESImprovement of hydraulic hoses between machine body and work equipmentThe length of the hoses which need to be replaced periodically is reduced by half to reduce the R&M cost.In addition, the hoses are less bent at their adapters to increase their durability.
