Description
Sure Seal – Retaining Couplers
When attached to an access fitting, the “Sure-Seal” retaining coupler automatically opens and depresses the valve core—all in one smooth action. Once disconnected, it traps refrigerant in the charging hose. Designed to be left permanently installed at the hose end, its seals remain compatible with newer refrigerants. And if internal parts ever need replacing, a parts kit is available.
