45° double return bend 1 5/8 ACR 9606 013000000

Professional brazed elbow for air conditioning systems

The double-socket elbow with a diameter of 1⅝ inches is a key component of refrigeration and air conditioning installations in inch-based systems. Made of high-quality copper, it ensures durable and leak-proof connections in HVAC applications, where manufacturing precision directly impacts the efficiency of the entire system.

Construction and materials

The component is made of pure copper, which is characterized by natural corrosion resistance and resistance to dezincification—the process of zinc degradation in brass alloys often encountered in refrigeration environments containing ammonia or other aggressive chemical agents.

The double-socket design provides exceptional mounting stability and enables professional high-seal brazed connections. Each end of the component features a socket for brazing, which guarantees even distribution of the filler material and minimizes the risk of pores or leaks.

Operating parameters and compatibility

The elbow has been designed in accordance with the requirements of the ANSI B16.22 standard, guaranteeing precise dimensions and component compatibility throughout the entire installation system.

The component is characterized by high pressure resistance across various operating temperature ranges. Under standard operating conditions from -20°C to +120°C, the elbow maintains full functionality at a working pressure of 19,3 bar. At elevated temperatures up to 150°C, the permissible pressure is 16,4 bar, while at an extreme temperature of 200°C, the component can operate under a pressure of 8,7 bar.

The component is intended for use with copper pipes meeting the requirements of the following standards:

• UNI EN 1057 (round copper tubes)
• UNI EN 12735-1 (round copper tubes for gas installations)
• UNI EN 12735-2 (round copper tubes for water installations)

Application and installation

The elbow finds wide application in professional air conditioning and refrigeration installations where 45° angle connections are required. The double-socket design facilitates precise routing of lines and minimizes pressure losses in the system.

Installation is performed using the hard brazing method with appropriate silver or phosphorus filler metals, adapted to the specifics of the refrigeration application. The component maintains full functionality across a wide range of operating temperatures—from industrial freezers (-20°C) to high-temperature applications (+200°C).

The product is covered by the standard manufacturer's warranty from the CONEX brand, ensuring protection against material and manufacturing defects when installed and operated correctly according to its intended use.
