Universal fit
This is a generic 3/4-inch straight compression union, not specific to any single truck make or model. It can be used on any system (air, fuel, oil, coolant) served by 3/4-inch copper, aluminum, or thermoplastic tubing, provided the pressure and temperature ratings are respected.

In a heavy‑duty truck or trailer context, these are commonly found in air brake systems, air suspension plumbing, or fuel and oil lines. You typically replace one when the old union has been overtightened, the ferrules are deformed, the threads are stripped, or the brass body has developed cracks or corrosion that cause air or fluid leaks.
