Red/Blue Anodized Aluminum Adapter, -06 Female JIC 37 deg Flare Swivel To -06 Female JIC 37 deg Flare Swivel, 90 deg Elbow

Correct on both counts. Each end is a -06 female JIC 37-degree flare swivel, so you're getting the same dash size and connection type on either side. The swivel feature on both ends gives you some rotational flexibility during installation, which makes it a lot easier to line things up without twisting the hose or fighting the fitting to get it seated right.

This Eaton Aeroquip adapter's made from anodized aluminum, which gives it good durability for demanding industrial jobs.

For routing in a tight spot, it’s a 90 degree elbow adapter with a -06 Female JIC 37 degree flare swivel on both ends, so it joins two -06 male JIC flare connections at a right angle.
