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).

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.
