SAE flare nut for refrigerant pipe 7/8", thread 1-3/16-12 UNF

SAE nut for 7/8″ refrigerant pipe, 1-3/16-12 UNF thread

SAE nut for 7/8″ refrigerant pipe is a professional fitting used in air conditioning, refrigeration and large capacity HVAC systems. Made of high quality brass, it ensures a tight, stable and high pressure resistant connection, making it suitable for industrial and commercial applications.

SAE nut for 7/8″ refrigerant pipe  is intended for copper pipes with an outer diameter of 7/8″ (22,2 mm) and uses standard flare thread 1-3/16″-12 UNF, frequently used in high-power HVAC installations and high-flow refrigeration circuits. The construction allows for seamless connections, through a mechanical tightening system.

The forged brass body offers excellent resistance to corrosion, vibration and temperature variations, helping to maintain a secure seal over the long term. Due to the high manufacturing precision, the SAE 7/8″ refrigerant pipe nut  reduces the risk of refrigerant losses and supports the efficiency of the installation.

The SAE nut for 7/8″ refrigerant pipe is used in industrial air conditioning installations, large capacity split and multisplit systems, heat pumps, commercial refrigeration equipment and applications HVAC It is compatible with a wide range of modern refrigerants, including R32, R410A, R407C, R134a, R404A, R507A, R1234yf and R744 (CO₂), but is not recommended for ammonia systems.

The assembly is done quickly, without welding, by correctly flaring the pipe and mechanically tightening the nut with an appropriate wrench. It is recommended to periodically check the joints to maintain operational safety.
