brennan adapter 20mj to 24 code 62 compa

Description & Features

Designed for high-pressure hydraulic systems requiring a directional change at the connection point, this 90-degree elbow adapter transitions from a 1-5/8-12 UN male JIC thread to a 1-1/2 inch Code 62 four-bolt flange. The Brennan 1804-20-24-FG is forged construction, placing it in Brennan's 1804-FG series and suited for demanding industrial hydraulic applications where fitting integrity under load is a priority.

The adapter accommodates a 1-1/4 inch tube O.D. and features an across-flats dimension of 1-7/8 inches. Overall installed dimensions measure 2.33 inches on L1 and 3.15 inches on L2, making it straightforward to account for in tight envelope assemblies. The Code 62 flange end is compatible with SAE J518 Code 62 split-flange connections, commonly used in higher-pressure hydraulic circuits.

If I'm swapping out an old fitting, how much space do I need to account for this 90-degree elbow?

For installation, you'll need to consider 2.33 inches (L1) and 3.15 inches (L2) to ensure proper clearance. Those are the overall installed dimensions.
