CHARACTERISTICS/BENEFITS
  • 70% of EN 857 2SC and 50% of EN 853 2SN bend radius at rated working pressure.
  • Superior flex impulse performance: tested to 600,000 impulse cycles.
  • Lightweight.
  • Alternative to spiral hoses in high pressure lines where flexibility is required.
  • M4K hose is compatible with biodegradable hydraulic fluids like synthetic esters, polyglycols and vegetable oils as well as petroleum-based fluids.
OPTIONAL M4K-MTF: the complete range of M4K is also available with the Gates special MegaTuff™ cover which offers 300 times the abrasion resistance of the standard M4K cover as per ISO 6945, superior ozone and weathering resistance. M4K-MTF is also suitable for in-oil (submersible) applications.
M4K-XTF: the complete range of M4K is also available with the gates special Xtratuff™ cover which offers 25 times the abrasion resistance of the standard M4K cover as per ISO 6945.
M4KH: for high-temperature applications, Gates recommends the M4KH hose range up to 121°c constant. Please refer to page 47.
