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).

IMPORTANT!
Hose and hose fittings series must be correctly matched. Using any fittings other than those specifically designated by the hose manufacturer for use with each specific hose can lead to hose assembly failure. Hose assembly failures have lead to damage, injury and death.
