Aeroquip Fuel Hose Fitting

Aeroquip Fuel Hose Fittings: Racing-Proven Connections for High-Performance Fuel Systems

When it comes to sealing a high-performance fuel system, the fitting at the end of the hose is every bit as critical as the hose itself. Aeroquip has been engineering precision hose fittings since 1940, when founder Peter F. Hurst secured patent rights for detachable, reusable hose fittings originally designed for aviation. That aerospace-grade heritage flows directly into every fuel hose fitting Aeroquip produces today.

Aeroquip fuel hose fittings are built around the brand's signature AN (Army-Navy) standard, which uses a 37-degree SAE flare sealing surface — the same geometry that has been trusted on aircraft and military vehicles for generations. This design creates a metal-to-metal seal that resists fuel permeation and withstands the vibration and thermal cycling that destroy lesser fittings over time.

Key Product Lines in the Aeroquip Fuel Hose Fitting Lineup

• AQP Reusable Aluminum Fittings — These compression-style, tool-free ends are designed to mate with Aeroquip's AQP racing hose. Fuel hose fittings in this family are available in straight, 45-degree, and 90-degree configurations across multiple AN dash sizes (commonly -6AN, -8AN, -10AN, and -12AN), making it straightforward to route lines around tight chassis obstacles.
• Socketless Aluminum Fittings — Engineered to work with AQP Socketless hose, these fittings require no special crimp tools or sockets. Assembly is accomplished by hand, dramatically reducing installation time while still delivering a secure, leak-free fuel connection.
• PTFE Racing Hose Fittings — For applications demanding maximum chemical resistance, Aeroquip offers steel hose ends specifically designed for their PTFE-lined racing hose. These fittings are available in SAE 37-degree flare configurations and are well suited for aggressive fuels, methanol, and high-pressure fuel injection systems.
• Reusable Steel Fittings — Where durability in high-heat environments is paramount, Aeroquip's steel reusable hose ends provide an extra margin of strength alongside excellent corrosion resistance.

What Sets Aeroquip Apart in This Category

Aeroquip offers AQP reusable compression-style fittings for methanol/nitromethane fuel systems, TFE steel fittings and hoses for hydraulic systems, and Socketless aluminum fittings for less weight and easy installation — a breadth of options that few competitors can match in a single brand. The result is a fuel system where every component, from hose to fitting, is engineered to work together.

Aeroquip hose fittings and adaptors are suitable for higher working pressures, temperatures, durability, and a longer life expectancy in comparison to like-for-like competitor products. For a performance build or a weekend race car, this translates into fewer leaks, less maintenance, and greater peace of mind at full throttle.

One of the most common ways the seat or cone on aluminum fittings can be easily damaged is by over-tightening; if a fitting has been over-tightened, it may be damaged and prone to leaks. Aeroquip addresses this by providing clearly documented torque specifications and a full line of dust caps to keep sealing surfaces contamination-free during assembly and storage.

Whether you're plumbing a carbureted street machine, a fuel-injected track build, or a dedicated drag racing application, Aeroquip's fuel hose fittings deliver the engineering depth and proven performance of a brand with over 80 years in fluid conveyance.
