CHARACTERISTICS/BENEFITS
  • Extremely flexible.
  • Superior flex impulse performance: tested to 1,000,000 impulse cycles at 50% of EN 856 R12 and SAE 100R12 bend radii.
  • 40% of EN 856 4SP bend radius at rated working pressure.
  • EFG3K hose is compatible with biodegradable hydraulic fluids like synthetic esters, polyglycols and vegetable oils as well as petroleum-based fluids.
OPTIONAL EFG3K-MTF: the complete range of EFG3K is also available with the gates special MegaTuff™ cover which offers 300 times the abrasion resistance of the standard EFG3K cover as per ISO 6945, superior ozone and weathering resistance.
IMPORTANT Please consult Gates Product Application Engineers for use of MegaTuff™ hose in reverse bending applications or for constant bending at minimum bend radius.
