#10 X 3/4-16 (#8) Radius O-Ring Fitting

The FRAGOLA #10 X 3/4-16 (#8) Radius O-Ring Fitting (part number 495105) is a precision straight adapter that bridges 8 AN male O-ring connections to 10 AN male ports. This aluminum fitting, finished in blue anodize for corrosion resistance, is engineered for high-pressure hydraulic and pneumatic systems where secure, leak-free connections are non-negotiable. The O-ring face seal design provides superior sealing integrity compared to traditional JIC fittings, making it essential in applications where system pressure consistency and safety are paramount.

The #10 designation on the female port and #8 (3/4-16) designation on the male end define the fitting's thread compatibility and flow capacity. The radius O-ring design—with its 37-degree flange and controlled clearances—distributes clamping load more evenly than straight-thread adapters, reducing the risk of galling and cross-threading during installation. Aluminum construction keeps weight minimal while maintaining structural integrity under dynamic pressure cycles, making this fitting suitable for both stationary systems and mobile equipment. The blue anodized finish provides additional protection against oxidation in humid or salt-air environments.

This adapter is widely used in aerospace, automotive racing, industrial hydraulics, and fluid-transfer applications where port size mismatches require a reliable intermediate fitting. Technicians and engineers specify FRAGOLA O-ring adapters when system documentation calls for proven, repeatable leak-free performance. The compact 1.7 x 1.4 x 4.1-inch profile and lightweight 0.07-pound design make installation straightforward without adding significant assembly bulk. Each fitting ships individually, allowing buyers to source exactly the quantity needed for their project or replacement inventory.
