#6 to #10 O-Ring Male Adapter Fitting

The MAGNAFUEL/MAGNAFLOW #6 to #10 O-Ring Male Adapter Fitting (MP-3021) is a precision straight adapter designed to connect AN-sized fuel system components with different port sizes. This aluminum fitting bridges a #6 AN male port to a #10 AN male port, making it essential for custom fuel system layouts where port size transitions are required without loss of flow integrity or seal reliability.

Constructed from lightweight aluminum and featuring purple anodized finish, this adapter delivers corrosion resistance in high-moisture environments—critical for vehicles operating in salt air or humid climates. The O-ring seal design provides a leak-free connection under pressure, eliminating the need for thread sealant tape and reducing potential contamination from Teflon particles in sensitive fuel systems. The straight configuration allows direct inline connection without directional constraints, simplifying installation in tight engine compartments or fuel cell mounting scenarios.

This adapter serves fuel system builders, restoration shops, and performance enthusiasts who require flexibility in component sizing during custom fuel line design. Whether transitioning between smaller supply lines and larger return lines, or connecting components from different manufacturers with incompatible AN ports, this fitting eliminates the need for multiple hose adapters. The compact 3 x 1.25 x 3.8-inch footprint and 0.06 lb weight ensure minimal impact on system layout or vehicle weight distribution, while MAGNAFUEL/MAGNAFLOW's reputation for quality manufacturing ensures consistent performance across thousands of operating hours.
