ADAPTER

Description & Features

This 45-degree elbow adapter from Brennan Industries connects a 1-5/8-12 UN male JIC thread to a 1-1/2 inch Code 62 flange, making it well suited for high-pressure hydraulic circuits where directional routing is required. The 45-degree elbow configuration allows lines to change direction within tight installation envelopes without requiring field bends or additional fittings.

Designed around a 1-1/4 inch tube OD, the adapter measures 4.65 inches along the primary axis and 1.81 inches on the flange end, with an across-flats dimension of 1-11/16 inches for wrench engagement. The male end designation confirms the external thread configuration on the JIC side of the fitting.

Reckon this adapter will hold up okay in a high-pressure hydraulic setup, or is it more for lighter-duty stuff?

Designed specifically for high-pressure hydraulic circuits, this 45-degree elbow adapter should work well where directional routing is needed.
