Steel Reusable 1 Wire Braid Reduced Bore Two-Piece Fitting, 9/16-18 Female JIC 37 deg Flare Swivel, -06 Hose, Straight

You are looking at a straight, two-piece reusable steel fitting for -06 hose with a 9/16-18 female JIC 37 degree flare swivel on the end.

Designed for use with one-wire braid hoses, this fitting should provide a secure, leak-free connection when properly installed. Ensure your hose is compatible with a -06 size fitting and has a 9/16-18 female JIC 37-degree flare swivel end.

The reduced bore on this fitting measures 0.375 inches, so yes, that checks out as a 3/8 inch bore. The hose end is sized for -06 hose, and the swivel end runs a 9/16-18 thread with a 37 degree flare seat. If your JIC port matches that thread and your hose is -06, you are in good shape.

Reduced bore fittings do carry a smaller internal flow path than a full bore version of the same hose size. For most hydraulic line applications running -06 hose, the difference is minimal and won't cause problems in typical circuits. Where it matters more is in high-flow or return line setups where pressure drop across fittings adds up. If your system is working within normal operating parameters for a -06 line, this fitting handles the job just fine.

It matches a -06 hose end and a 9/16-18 Female JIC 37 degree flare swivel (SAE 37). It’s a straight, two-piece reusable fitting in the Danfoss/Eaton 4401 Series made for 1 wire braid reduced bore hose.
