AN to O-Ring -12 x 1 1/16-12 (-12)

The AN to O-Ring -12 x 1 1/16-12 (-12) adapter is a straight-through hydraulic and pneumatic fitting designed to connect two 12 AN male ports with o-ring sealing. Manufactured from aluminum and finished in black anodized coating, this adapter delivers corrosion resistance and clean aesthetics for high-pressure fluid systems. The o-ring face seal (ORFS) design creates a leak-free connection critical in fuel systems, hydraulic brake lines, and pressurized cooling circuits where vibration and thermal cycling demand reliable port-to-port compatibility.

This -12 AN adapter handles the standard 12 AN thread size (3/4-12 UNF) and accommodates flows across automotive, aerospace, and tactical equipment applications. The o-ring sealing method provides a positive seal without relying on thread-applied sealant, reducing assembly risk and simplifying field maintenance. Black anodized aluminum construction resists oxidation in salt air and corrosive environments while maintaining lightweight characteristics—ideal for weight-sensitive platforms. Compact dimensions (2.3 x 1.35 x 3.05 inches) and minimal weight (0.08 lbs) integrate seamlessly into tight engine bays and chassis layouts.

Preferred by fabricators and system designers working with fuel injection systems, hydraulic suspension platforms, and custom cooling circuits, this straight male-to-male AN fitting eliminates offset requirements when port alignment permits direct connection. The o-ring seal standard ensures compatibility with AN system hoses and components already specified for ORFS connections, streamlining sourcing and reducing cross-threading risk during installation.

For buyers sourcing AN adapters, whether for high-performance automotive builds, hydraulic equipment, or pressurized fluid management, verified AN specifications and proven ORFS sealing technology are non-negotiable. This -12 x 1 1/16-12 adapter meets those demands with precision engineering and corrosion-resistant materials.
