Fitting that joins a copper pipe to a threaded pipe, valve, or component. It has two ends: one is a "sweat" or solder cup to connect to a copper pipe, and the other is a male thread that screws into a female threaded opening. These adapters are often used in potable water, HVAC, or other pressurized systems to transition between copper tubing and threaded metal parts. Need larger quantities?
