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
