SAE flare nut for refrigerant pipe 5/8", thread 7/8-14 UNF

SAE flare nut for refrigerant pipe 5/8", thread 7/8-14 UNF

SAE nut for 5/8″ refrigerant pipe is a connecting element used in air conditioning, refrigeration and HVAC systems. Made of high-quality brass, this nut provides a leak-proof, pressure-resistant connection and is suitable for professional use in refrigeration circuits.

SAE nut for 5/8″ refrigerant pipe is intended for copper pipes with an outer diameter of 5/8″ (15,88 mm) and uses standard flare thread 7/8″-14 UNF, frequently found in air conditioning and refrigeration installations. The construction allows for seamless connections, through a mechanical tightening system.

The forged brass body offers excellent resistance to corrosion, vibration and temperature variations. This helps maintain a stable seal and reduces the risk of refrigerant loss during operation. Due to its precise machining, the SAE 5/8″ refrigerant pipe nut is compatible with high-pressure applications, being recommended up to approx. 140 bar.

SAE nut for 5/8″ refrigerant pipe is widely used in split and multisplit air conditioning installations, heat pumps, commercial refrigeration equipment and industrial applications HVACIt is compatible with a wide range of modern refrigerants, including R32, R410A, R407C, R134a, R404A, R507A, R1234yf and R744 (CO₂)Not recommended for use in ammonia systems.

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