The Flare Nut is a precision-engineered threaded fitting used in flare connection systems to create secure, leak-resistant joints in gas, HVAC, and refrigeration pipelines. It is designed to compress flared tubing ends for strong and reliable sealing.
The Flare Nut is a mechanical fastening component used in flare fitting systems to connect tubing securely without welding or soldering. It works by tightening over a flared tube end, compressing it against a mating flare fitting to create a strong, leak-resistant seal.
Manufactured from brass, steel, or copper-compatible alloys (depending on application), flare nuts are widely used in refrigeration, air conditioning, gas distribution, and hydraulic systems. Their design ensures high-pressure sealing performance in systems where vibration resistance and reliability are critical.
Flare nuts are commonly paired with copper or soft metal tubing and are essential in HVAC installations and automotive fluid systems. They are available in various sizes depending on tube diameter and thread specifications.
Material type, thread standard, and pressure rating may vary depending on manufacturer and application requirements. Proper torque application is essential to ensure correct sealing and prevent leakage.
