It works with a matching compression sleeve (ferrule) and a fitting body to create a secure, leak-proof mechanical connection—no flaring or soldering required. On heavy-duty trucks and trailers, you’ll find it on air brake lines, fuel lines, and other fluid systems. Replace it when the threads are stripped, the hex is rounded, or the nut has corroded and can no longer hold pressure.
