It threads onto a fitting body with a 17/32-24 straight thread, securing the tube and sleeve assembly to form a leak-tight connection. You replace it when the threads are damaged, the nut is cracked, or the hex corners are rounded off, ensuring the air brake system remains safe and functional. It’s a standard DOT-compliant component used throughout heavy-duty air brake and auxiliary air systems.
