Steel Reusable 1 Wire Braid Reduced Bore Fitting, 2.38 Inch Code 61 Split Flange, -24 Hose, Straight

This fitting is made for a -24 hose size.

The key callouts on this one are right in the name: it is a straight reusable fitting for a -24 hose, built as an SAE Code 61 split flange connection with a 2.38 inch Code 61 flange size.

Reduced bore means the internal passage through the fitting is smaller than the flange's nominal 2.38 inch Code 61 face size. The bore dimension on this fitting comes in at 2.56 inches for the D measurement, but the internal flow path through the hose end is sized to match the -24 hose it connects to rather than running the full flange diameter. In practice, that means you get a slight restriction compared to a full bore version at the same flange size. For most return line or lower-velocity applications it's a non-issue, but if you're pushing high flow rates through a tight circuit, it's worth accounting for in your pressure drop calculations before you commit.
