Red/Blue Anodized Aluminum Reusable Socketless Fitting, -10 Hose & Female JIC 37 deg Flare Swivel, 45 deg Elbow

Socketless fittings like this one go together without crimping equipment or external clamps. You slide the hose onto the fitting and secure it mechanically, which cuts down on assembly time and means you're not dependent on shop equipment to get it done. That's a big part of why folks running field repairs or smaller use tend to reach for these.

Socketless is the key part here. It’s a reusable socketless fitting for -10 hose size, and the design is meant to eliminate the need for clamps during assembly.
