Cooling System Pressure Tester Adapter Mityvac

The MV4508 Universal Cooling System Adapter is simple and quick to install in virtually any radiator or coolant reservoir neck. The rubber, step-and-cone design features a self-docking, nested cam and internal restrictor that combine to provide a secure, airtight seal with only a single rotation of the expansion knob. The unique adapter is fully self-contained (no component change is required) so there are no extra parts to maintain. Also, its compact size allows for convenient storage in a toolbox. Economical alternative to application-specific adapters. It fits pressure pumps with a common radiator neck-style connection and replaces more than 20 individual adapters used to pressure test the cooling systems on cars, vans and light and heavy-duty trucks.
