ACR Fittings ASTM B280 | Leak-Free Copper Fittings for HVAC-R

ACR Fittings ASTM B280 play a critical role in modern air conditioning and refrigeration systems, where reliable copper tube connections directly affect efficiency, safety, and service life. ASTM B280 specifies seamless copper tube for air conditioning and refrigeration field service, defining requirements for chemical composition, temper, and dimensions. Fittings used with such tubing must therefore match these material expectations to ensure compatibility, pressure integrity, and thermal performance. Our ACR Fittings ASTM B280 are manufactured to align with these requirements, using high-precision machining and rigorous quality control. They are suitable for HVAC-R contractors, OEM equipment builders, and distributors serving North America, Europe, the Middle East, and Asia-Pacific. In refrigeration cycles, even minor leaks can reduce efficiency and increase energy consumption. Precision fittings help minimize refrigerant loss, support proper system evacuation, and maintain stable operating pressures. Copper’s natural corrosion resistance and recyclability also contribute to sustainable building and appliance designs. Our global outlook and 19 years of experience allow us to support diverse technical standards and cultural expectations, delivering dependable ACR Fittings ASTM B280 for plumbing, air conditioning, refrigeration, gas, and medical piping systems.
