Everbilt 3/4 in. Copper Pressure Cup x Cup Coupling with Stop Fitting (10-Pack)

Wrot Copper Couplings with rolled stops are designed to connect two matching-sized copper pipes. The rolled stop construction prevents a pipe from following through the fitting, preventing the fitting from moving when soldering. A unique feature of working with copper is that this material is safe and reusable, copper has no harmful chemicals or other elements and can be easily recycled, which is ideal for sustainable building efforts.
