SAE flare nut for refrigerant pipe 3/4", thread 1-1/16-14 UN

SAE flare nut for refrigerant pipe 3/4", thread 1-1/16-14 UN

SAE nut for 3/4″ refrigerant pipe is a fitting used in HVAC installations, air conditioning systems and refrigeration applications. Made of high-quality brass, it ensures a tight, stable and high-pressure resistant connection, making it ideal for professional use in refrigeration circuits.

This model pSAE nut for 3/4″ refrigerant pipe is intended for copper pipes with an outer diameter of 3/4″ (19,5 mm) and uses standard flare thread 1-1/16″-12 UNF, frequently found in installations HVAC high capacity. The construction allows for seamless connections, through a mechanical clamping system.

The forged brass body offers excellent resistance to corrosion, vibration and temperature variations, ensuring a secure long-term seal. Thanks to the precision manufacturing, the SAE nut for 3/4″ refrigerant pipe  helps reduce refrigerant losses and maintain system efficiency.

SAE nut for 3/4″ refrigerant pipe is used in split and industrial air conditioning installations, heat pumps, commercial refrigeration equipment and systems HVAC high power. It is compatible with a wide range of modern refrigerants, including R32, R410A, R407C, R134a, R404A, R507A, R1234yf and R744 (CO₂), but it is not recommended for use with ammonia.

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