Aeroquip Flare Fitting
Aeroquip Flare Fittings: Decades of Precision Fluid Conveyance
When it comes to reliable, leak-free fluid connections, Aeroquip has been the name that engineers and performance enthusiasts trust since the brand's founding in 1940. What began as a revolutionary approach to detachable, reusable hose fittings for the aviation industry has evolved into one of the most comprehensive flare fitting lineups in the automotive and industrial world. Aeroquip's flare fittings carry that same DNA — precision-engineered to hold tight under pressure, temperature extremes, and the vibration that comes with real-world use.
What Makes Aeroquip Flare Fittings Stand Out
Aeroquip's flare fitting portfolio spans several key connection standards, giving builders and technicians the flexibility to tackle virtually any plumbing application. Their offerings include fittings compatible with both SAE 37° (AN/JIC) and SAE 45° flare standards, as well as inverted flare designs — a critical distinction when working with brake lines, power steering systems, fuel injection conversions, or hydraulic circuits. Notably, many Aeroquip fittings are engineered to mate with both 37° (AN) and 45° male flares, providing versatility across mixed-specification systems.
The 210 Series inverted flare conversion adapters are a standout example — available in a range of tube O.D. sizes, they allow builders to bridge different line diameters using the familiar inverted flare seat-to-male configuration. The 2000 Series brass straight adapters bring the same Aeroquip standard to SAE 45° flare applications, offering solid brass construction and compliance with SAE J514 dimensional standards, with a working temperature range of -65°F to +250°F.
For performance and racing applications, Aeroquip's flare fittings integrate seamlessly with their broader ecosystem of SOCKETLESS™ hose assemblies and Teflon/PTFE racing hoses. Reusable SAE male inverted flare fittings — available in straight, 45°, and 90° elbow configurations in both steel and aluminum — are designed for use with Aeroquip's Teflon-lined hose and are equally at home in off-road brake circuits, transmission lines, clutch systems, nitrous oxide setups, gauge lines, and power steering applications.
Engineering Integrity Across Every Connection
What truly sets Aeroquip apart in the flare fitting category is the brand's insistence on treating hose and fittings as a matched system. Each fitting is engineered and tested to work in concert with its designated hose assembly, ensuring tolerances remain tight and seals remain leak-free under demanding conditions. This philosophy — built on more than 80 years of fluid conveyance expertise — means that choosing Aeroquip flare fittings is choosing a component that's been validated as part of a complete, pressure-rated assembly rather than an isolated part.
Whether you're routing brake lines on a performance build, converting a factory fuel injection system to AN-style plumbing, or upgrading a marine power trim circuit, Aeroquip's flare fittings deliver the precision and durability that the application demands.
