About Earl's Performance:

Earl's Performance Products was founded by Earl Fouts in 1955 in Lawndale, California, with a mission to supply high-quality military aircraft surplus plumbing components directly to the racing industry. As the military surplus market dried up, Earl pioneered his own comprehensive range of hoses and fittings still used today — and in doing so, created the racing aftermarket AN plumbing industry. Earl's invented most of the special-purpose racing adapters and introduced the flexible armored PTFE-lined hose to the racing industry in the 1960s. Today, Earl's is renowned as the world's foremost motorsport hose and fittings source, with plumbing found on the vast majority of Indy 500 winners and relied upon by top funny car, sprint car, and Indy car teams worldwide. These stainless steel AN to NPT straight adapters carry that same racing-proven heritage, making it straightforward to integrate modern AN hose systems with traditional NPT-threaded components across any high-performance fluid routing application.
