180° copper return bend for HVAC and refrigeration piping. C12200 wrot copper, ASME B16.22 compliant. C x C sweat-end design changes pipeline direction 180° in heat exchangers and condenser coils. Sizes 1/4″ to 2-1/8″ OD. Max pressure 700 psi, temp range -20°F to +400°F.
Our Copper Return Bend is a precision-engineered wrot copper fitting designed to change pipeline direction by 180 degrees in air conditioning, refrigeration, and heat pump systems. It is widely used in heat exchanger hairpin tubes, condenser coils, and evaporator assemblies, where refrigerant flow must reverse direction within a compact space.
Manufactured from high-purity C12200 phosphorus-deoxidized copper, the return bend features a sweat-end (C x C) design with precision-machined solder cups, ensuring a consistent capillary gap for reliable brazing. The seamless, one-piece wrot construction eliminates weld seams, reducing potential leak points in high-pressure refrigerant circuits.
