Air Conditioning Copper Pipe Fittings | EN12541 & ASME B16.22 Certified

Air Conditioning Copper Pipe Fittings are the backbone of modern HVAC and refrigeration pipe connection systems. Copper remains the preferred material because of its superior thermal conductivity, resistance to corrosion and ability to form durable, leak-tight joints under high pressure and temperature cycling. In air conditioning and refrigeration lines, engineers specify ACR Fittings and End Feed Fittings to ensure smooth refrigerant flow and minimal energy loss. Our End Feed Fittings comply with EN12541, ASME B16.22 and AS 3688, three widely recognized standards that guarantee dimensional accuracy, material integrity and reliable performance across different regions. For installers, Press Fittings reduce labor time and eliminate open-flame risks, while Solder Ring Fittings offer a traditional, robust connection for plumbing and gas systems. Understanding that customers across Europe, North America, Australia and the Middle East have different installation habits and codes, we design our Air Conditioning Copper Pipe Fittings to be compatible with multiple joining methods and to maintain consistent quality batch after batch. As a high-precision manufacturer based in Zhejiang with a global outlook, we combine efficient, eco-friendly production with strict quality control, helping contractors, wholesalers and OEM partners reduce callbacks and total installed cost. Whether the project involves residential air conditioning, commercial refrigeration, gas piping or medical piping systems, selecting the right copper fittings is critical to safety, efficiency and long-term reliability—and our portfolio is built to deliver exactly that.
