The ARMSTRONG Reducer Coupling is a solderless mechanical fitting designed to permanently connect two straight lengths of hard copper tubing that have different diameters, utilizing the same proprietary torque-activated sealing ring technology on both ends to create a direct, leak-proof transition between sizes without the need for brazing or a flame. This provides a fast, safe, and reliable solution for adapting line sets in HVAC/R refrigerant and hydronic piping systems where a simple, inline pipe size change is required.
