721ST | 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 721ST Series hydraulic hose will no longer be fulfilled beginning June 28, 2019. Please use 722ST (-8, -10, -12, -16) or 487ST (-20) as a replacement.

Parker 721ST hose is a high-pressure compact hydraulic hose designed for high pressure applications where space is limited and abrasion resistance is required. With its one-half SAE 100R12 minimum bend radius and Super Tough Cover, Parker 721ST hose enables you to use less hose while guarding against hose-to-hose and hose-to-object abrasion.

  • One-half SAE 100R12 minimum bend radius means using less hose
  • Specially engineered Tough Cover compound resists abrasion in aggressive environments
  • 721ST hose is great for applications demanding up to 4000 psi working pressure.
  • Look for a unique three-color layline for easy identification of Parker 721TC hose.
  • Available without abrasion resistant cover (721 hose) or with Parker Tough Cover for  abrasion resistance with smaller outside diameter (721TC hose).
