It is used to change the direction of air flow in truck and trailer pneumatic systems when transitioning from flexible nylon tubing to a rigid threaded port. This fitting is commonly used on air brake, suspension, and accessory air systems, especially where DOT-approved nylon tubing is required. It is typically replaced when the original fitting is cracked, cross-threaded, or the internal grab ring and O-ring seal wear out, causing an air leak.
