It reinforces the tubing wall so that when a compression nut and ferrule are tightened, the tube does not collapse, creating a secure, leak-free connection. These inserts are commonly used in heavy-duty truck and trailer air brake systems, air suspension, and air-operated accessories. They are typically replaced whenever air lines are cut, reworked, or when installing new compression fittings.
