Steel Reusable 1 Wire Braid Reduced Bore Fitting, 1-5/16-12 Female JIC 37 deg Flare Swivel, -16 Hose, 45 deg Elbow

Reduced bore means the internal flow path is narrower than a full-bore -16 fitting. The hose end is still sized for a -16 hose, so it connects correctly, but the bore through the fitting body itself is stepped down. That tradeoff lets the fitting work in tighter envelope spaces without changing your hose size. If flow restriction is a concern for your application, that's worth factoring in before you commit to it.

It’s built for a -16 hose and uses a 1-5/16-12 Female JIC 37 degree flare swivel end. It’s also a 45 degree elbow, so it’s meant to turn the line while keeping that JIC 37 flare connection style.

The hex size is 1.44.
