When attached to an access fitting, the Sure Seal™ Retaining Coupler automatically opens and depresses the valve core all in one action. When disconnected, it traps refrigerant in the charging hose. Leave it permanently installed on the end of the hose. The seals are compatible with newer refrigerants, and if internal parts need replacing, a parts kit is available.
