Male Hardline Tube Nut Earl's 3/8-24 I.F For 3/16 Tubing

Founded in 1955 by Earl Fouts in Lawndale, California, Earl's Performance Products began by supplying high-quality military aircraft surplus plumbing components directly to the racing industry from a small retail outlet.

As the military surplus market diminished, Earl recognized the need for a continuous supply for the racing market and pioneered the Earl's range of hoses and fittings that are still utilized today.

In doing so, he created the racing aftermarket plumbing industry.

In 1973, Earl's Performance invented the self-indexing hose end, known as the 'Swivel Seal', which allows 360-degree adjustment after installation, simplifying plumbing tasks.

Earl's invented most of the special-purpose racing adapters, the full billet hose clamp housing, and introduced the flexible armored PTFE lined hose to the racing industry during the 1960s.

Earl's racing heritage is unmatched and is arguably the most successful plumbing in history.

Top funny car teams, sprint car teams, and Indy car teams continue to rely on Earl's today.

Earl's plumbing has been featured on the majority of Indy 500 winners.

Earl's Performance Plumbing has distribution outlets worldwide.

Earl's offers the most comprehensive line of performance plumbing available and is recognized as the leading source for motorsport hoses and fittings.

Manufacturing is based in Bowling Green, KY, with three distribution and assembly sub-locations in Indianapolis on Gasoline Alley, Earl's UK at Silverstone, and Earl's Australia in Sydney.
