This is a NAPA Solutions (Dorman 926-165) Radiator Coolant Hose O-Ring Kit.
Designed to match the fit and function of original equipment O-rings on specified vehicles.
Engineered to help securely seal hose connections when an existing O-ring has failed.
Compatible with select Ford F-250, F-350, F-450, and F-550 Super Duty models from 2008-2016.
Allows replacement of just the O-ring rather than the entire hose assembly.
