Earl's Performance Stainless Steel AN to NPT Adapter Tee Fittings

Earl's Performance Stainless Steel AN to NPT Adapter Tee Fittings provide reliable, leak-free connections wherever a fluid line must simultaneously branch and transition between AN (Army-Navy) and NPT (National Pipe Taper) thread standards. Precision-machined from premium stainless steel, these tee adapter fittings are engineered for the rigorous demands of motorsport and high-performance street applications alike.

Key Features:

• Stainless steel construction delivers superior corrosion resistance and long-term durability across fuel, oil, coolant, brake, and hydraulic fluid systems
• Precision-machined threads ensure accurate fit, proper seating, and dependable sealing integrity with minimal sealant required
• Tee configuration allows a single line to branch in two directions while simultaneously converting between AN and NPT thread standards — ideal for adding pressure sensors, gauge ports, or auxiliary lines without compromising flow
• Broad fluid compatibility makes these fittings suitable for fuel systems, oil lines, coolant circuits, brake systems, and general hydraulic plumbing
• Multiple size combinations available across the product line to accommodate a wide variety of custom plumbing configurations and build requirements
• Made in the USA to Earl's exacting quality and craftsmanship standards

About Earl's Performance:

Earl's Performance Products was founded by Earl Fouts in 1955, initially supplying military aircraft surplus plumbing components to the racing industry. As the surplus market declined, Earl pioneered his own range of hoses and fittings — effectively creating the racing aftermarket AN plumbing industry. Earl's invented most of the special-purpose racing adapters in common use today and introduced flexible stainless steel PTFE-lined hoses to racing in the 1960s. Today, Earl's remains a trusted supplier for top motorsport teams worldwide, with plumbing relied upon across IndyCar, funny car, sprint car, and high-performance street builds.
