Elevate your HVAC, refrigeration, and copper tubing projects with the Evangenial SAE 45° Brass Flare Nut Kit. This 5‑piece set delivers precise, reliable connections for a range of tube sizes: two 1/4″ OD nuts (7/16″‑20 threads), two 3/8″ OD nuts (5/8″‑18 threads), and one 1/2″ OD nut (3/4″‑16 threads). Designed exclusively for SAE 45‑degree flared tubing, these female flare nuts provide a robust sealing interface when paired with the matching male flare fittings.
Each nut is forged from solid brass, ensuring durability and corrosion resistance in demanding service environments. The hex‑flat design offers wrench‑ready access, while the machined female threads provide a secure clamping force once the flare is seated. Whether you’re repairing a mini‑split line set, upgrading an air‑conditioning system, or replacing copper tubing in refrigeration equipment, this kit delivers the precision and reliability professionals expect.
