Earl's Performance AN to Inverted Flare Adapter Fittings

Earl's Performance AN to Inverted Flare Adapter Fittings provide a trusted, precision-engineered solution for connecting AN-style fittings to standard 45-degree inverted flare lines. Designed for professional builders, racers, and performance enthusiasts, this product line delivers the leak-free reliability and exacting fit that Earl's Performance has built its reputation on for decades — across brake lines, fuel systems, power steering, transmission cooling, and general hydraulic plumbing.

A key engineering refinement throughout this line is the extended thread length on the inverted flare end. Older-style fittings could bottom out on the threads before the flare fully seated, preventing a proper seal. This improvement eliminates that failure point, ensuring consistent and secure connections across every variant in the line.

Key Features:

• Aerospace-grade materials — manufactured from steel or aluminum alloys that meet and exceed minimum requirements for aerospace fittings
• Precision-machined to exacting tolerances for reliable, leak-free fluid connections
• Extended inverted flare thread length prevents bottoming out before full flare seat engagement
• Multiple material options — steel variants suited for high-pressure applications such as power steering; aluminum variants ideal for brake, fuel, and general hydraulic use
• Multiple finish options available across the product line to suit a variety of builds and aesthetics
• Straight and angled configurations available to accommodate a wide variety of plumbing layouts
• Compatible with standard inverted flare brake lines, fuel delivery systems, transmission cooler lines, and related hydraulic plumbing

Earl's Performance has been a cornerstone of fluid transfer technology in professional motorsport and the performance aftermarket for decades. These AN to Inverted Flare Adapter Fittings reflect that legacy of precision engineering — making them a go-to choice wherever AN plumbing meets factory-style inverted flare lines.
