20HB-20MAORB 90 DEG ELBOW

That's the setup this fitting handles. One end is a 1-1/4 inch hose barb, the other is a 1-5/8-12 male SAE adjustable O-ring boss, and the whole assembly sits at a 90-degree angle between the two. The O-ring seal material is NBR, and the body is forged steel. If your port matches that 1-5/8-12 SAE thread spec, you're good to go.
