0.625 (1/2 NPS) x 12 inches, Copper Round Tube, Type L

C122 hard drawn copper round tubing refers to a specific type of hard drawn copper tube that is made from C122 copper alloy. C122 copper is a commercially pure copper alloy that contains a small amount of phosphorus, which improves its strength and machinability. Hard drawn C122 copper round tubes are commonly used in applications that require high strength and durability, such as plumbing, HVAC, and refrigeration systems. The hard drawing process gives the tube increased hardness, making it resistant to damage from bending or other forms of deformation. Actual OD is always 1/8 inch larger than listed tube size on copper tubes.
