16x1x48mm 180° Elbow Copper End Feed Welding Pipe Adapter for Air Conditioner and Refrigerator systems A compact, durable copper 180° elbow designed for endfeed welding connections in HVAC and refrigeration lines. This adapter allows a complete Uturn with a single fitting, simplifying routing in tight spaces and reducing the number of joints. Made from copper for reliable conductivity and corrosion resistance, it is intended for use with 16x1x48mm pipe dimensions. Key benefits Spacesaving 180° turn: Provides a full Uturn in one fitting so you can route lines in compact or confined areas without multiple elbows or extended bends. Reliable endfeed welding joint: Designed for endfeed welding (brazing/soldering) to create strong, leakresistant connections when installed properly. Built for HVAC and refrigeration: Specifically intended for air conditioner and refrigerator piping applications where durable copper fittings are required. Consistent fit: Sized to match 16x1x48mm copper tubing, ensuring a precise connection and minimizing the need for additional adapters. Key attributes Shape: 180degree elbow (Uturn) Connection type: End feed (welding/brazing) Material: Copper Nominal size: 16x1x48mm (fits tubing specified as 16x1x48 mm) Typical applications: Air conditioner and refrigerator refrigerant and liquid lines Typical use cases Tightspace routing in HVAC installations: Use the 180° elbow to reverse refrigerant piping direction behind condensers or inside ductwork where space does not allow gradual bends. Refrigerator or appliance : damaged or corroded Ubends on refrigeration lines with a single, welded copper elbow for a compact, secure . Line set terminations and returns: Create neat, compact loops or serviceable connections near evaporators or receiverdrier assemblies where a single 180° fitting reduces joints and potential leak points. Installation notes This adapter is intended for endfeed welding (brazing/soldering). Proper cleaning, fluxing, and correct brazing technique are required to achieve a reliable joint. Use appropriate filler material and follow industry practices for HVAC/refrigeration brazing methods. Pressure test the system after installation and leakcheck according to applicable codes and manufacturer instructions. Installation should be performed by a qualified technician familiar with refrigeration and air conditioning systems. Packaging and handling Handle with care to avoid kinks or deformation prior to installation. Store in a dry environment to prevent surface contamination before welding. This 16x1x48mm 180° elbow copper endfeed welding adapter is a straightforward, dependable choice for professionals and technicians needing a compact Uturn fitting for air conditioner and refrigerator copper piping.
