Copper Return Bend for 3/4" Tube
This wrot copper fitting connects two 3/4 inch nominal tubes using a C x C sweat joint. The outside diameter measures 7/8 inch and the component meets ASME/ANSI B16.22 standards for pressure fittings. It suits residential and light commercial plumbing installations.
Fits standard copper pipe assemblies
The sweat connection requires flux and solder to form a permanent, leak-free joint. No threading, flanging or mechanical crimp tools are needed, freeing the installer from specialised press equipment. The compact bend radius allows routing in tight stud bays or joist spaces.
Withstands sustained pressure and temperature
Rated for 582 psi at 100 °F, the fitting maintains integrity across a continuous range of -20 °F to 400 °F. Copper construction resists corrosion and scaling during long-term hot-water or hydronic heating service. The joint strength remains stable through repeated thermal cycling.
