4000 PSI Constant Working Pressure Hose (721ST)

Hydraulic – SuperTough Cover SAE 100R12 / ISO 3862-1 TYPE R12 / EN 856 TYPE R12

4000 PSI Constant Working Pressure Hose 721ST

The Parker 721 family of hoses pushes the envelope in high-pressure applications where space is tight. Critical high-pressure applications in limited spaces calls for 721 hose. With its one-half SAE 100R12 minimum bend radius and abrasion resistant cover offering, 721 hose enables you to use less hose while guarding against hose-to-hose and hose-to-object abrasion. No matter how demanding the environment, 721 hose will keep your equipment working hard.

  • One-half SAE 100R12 minimum bend radius means you use less hose
  • Specially engineered Tough Cover compound resists abrasion in aggressive environments
  • Up to 4000 psi working pressure
  • Unique three-color layline makes hose easy to identify
