Steel Reusable 1 Wire Braid Reduced Bore Fitting, 7/8-14 Female JIC 37 deg Flare Swivel, -10 Hose, Short 90 deg Elbow

Fit comes down to the connection details. This one is a short 90 degree elbow for -10 hose with a 7/8-14 female JIC 37 degree flare swivel on the end. If your existing fitting uses that same 7/8-14 JIC 37 flare female swivel and it is for -10 hose, you are looking at the same basic hookup.

Constructed with high-grade steel, this fitting is designed to withstand challenging conditions, so it should be suitable for the hydraulic system on a farm tractor.

Reduced bore fittings do flow slightly less than full bore versions at the same hose size, yes. The internal passage is a bit narrower, which is a tradeoff you get with the short 90-degree elbow geometry. For most hydraulic circuits running standard working pressures on a -10 hose, the difference is minor and well within acceptable limits. Where it matters more is in high-flow, low-pressure-drop applications, so just make sure your system isn't one that's sensitive to even small restrictions before you commit to it.
