721 | Parker High Pressure Compact Hydraulic Hose

NOTE: To consolidate its product offerings, Parker will discontinue manufacturing several hose series that can are replaced with GlobalCore hose. Orders for 721 Series hydraulic hose will no longer be fulfilled beginning June 28, 2019. Please use 722 (-6, -8, -10, -12) or 487 (-20, -24, -32) as a replacement.

Parker 721 hose is a high-pressure compact hydraulic hose designed for high pressure hydraulic applications where space is limited. With its one-half SAE 100R12 minimum bend radius, Parker 721 hose enables you to use less hose and is easier to install in tight places.

  • One-half SAE 100R12 minimum bend radius means using less hose
  • Specially engineered Tough Cover compound resists abrasion in aggressive environments
  • 721 hose is great for applications demanding up to 4000 psi working pressure.
  • Available with Parker Tough Cover for great abrasion resistance (721TC hose) or with Parker Super Tough Cover for ultimate abrasion resistance (721ST hose).
