Used to disconnect transmission oil cooler lines . Purple anodized aluminum construction. Quick line removal. Will clear the flare and disconnect the new style clips Applications: 2003 and 2004 Ford Explorer (V8), 2004 Ford F150, and 2004 Cadillac CS.

The locking clip used in the fitting is different than the standard 'tabs' used on most other applications. The ASS8021 will clear the flare and disconnect the new style clips with ease.
