#10 X 7/8-14 (10) Radius O-Ring Fitting

The #10 X 7/8-14 (10) Radius O-Ring Fitting from FRAGOLA is a precision adapter designed for high-performance hydraulic and fuel line systems that demand reliability under pressure. This straight male-to-male O-ring fitting serves technicians, fabricators, and performance enthusiasts who require leak-free connections in critical applications. The 10 AN port sizing makes this fitting ideal for mid-to-high flow rate systems where secure, repeatable connections are non-negotiable.

Constructed from lightweight aluminum and finished in blue anodized coating, this fitting combines corrosion resistance with minimal weight penalty—critical for racing, aerospace, and marine applications. The 7/8-14 radius O-ring design eliminates the need for separate crush washers, creating a consistent, reusable seal that can be disconnected and reconnected without sacrificing integrity. The straight configuration allows for direct, low-profile mounting without angular offsets, reducing turbulence and pressure drop across the connection point.

Performance-minded builders choose FRAGOLA O-ring fittings for fuel systems, cooling circuits, and transmission cooler lines where vibration tolerance and thermal cycling durability matter. The compact 3.9 x 1.4 x 5.15-inch profile fits tight engine bays and frame rails, while the lightweight 0.07-pound construction keeps system weight to a minimum. This single fitting (sold individually) integrates seamlessly into both custom and factory harness upgrades, delivering the professional-grade reliability that separates quality builds from amateur installations.
