Special Purpose Adapters

Earl's offers the most complete line of adapter fittings in the industry. In addition to the standard range of AN adapters in both aluminum and steel, for over the past 30 years Earl's has designed and manufactured a wide selection of special adapter fittings to meet the needs of the racing industry. These specials include metric to AN, inverted flare to AN and power steering fittings.

Refer to the Technical Section for AN number to tube size conversion.

Note: Because we deal predominately with motorcycles, we usually only stock -3, -4, and -6 sizes. We can special order anything Earl's offers.
