Brass Reusable Socketless Fitting, 7/16-24 Female SAE 42 deg Inverted Flare, -04 Hose, Straight

Socketless fittings like this one go on without any special crimping equipment or socket tools. You work the hose end onto the fitting by hand, which makes field installation and replacement a lot more straightforward than dealing with crimped assemblies. That reusable designation means you can take it back off and put it on again if needed, so you're not throwing away hardware every time you service a line.
