Question by: Travis T on Oct 1, 2025, 10:40 AM
Will this flare nut work as a replacement part on my Aeroquip setup with half inch tubing?
Answer by: Customer Support on Oct 3, 2025, 6:42 AM
Yes, this flare nut fits 0.50 inch OD tube and works with JIC 37 degree flare connections. It's manufactured as part of the Aeroquip by Danfoss 1290 Series Versil-Flare system, so it'll be compatible with your existing Aeroquip fittings that use the same tube size and flare angle.
