Earl's Performance Plumbing produces innovative AN plumbing components, hoses, and fittings for the motorsports industry. In the 1960s, Earl’s made a name for itself with the introduction of flexible Stainless Steel PTFE-lined hoses—and while this hose type has been replaced with modern solutions, Earl’s went on to produce more industry-changing auto plumbing parts. Earl's patented self-indexing adjustable hose end, known as the "Swivel Seal,” was a game-changer thanks to the ability to adjust 360 degrees after installation. This same eye for modernization and improvement has kept the company on top for decades. Earl’s Performance Plumbing continues to produce the most sought-after AN fittings, special-purpose racing adapters, brake lines, hose ends, and auto plumbing in the world.
