Earl's Performance 45-Degree Aluminum NPT Hose End Fittings

Earl's Performance 45-degree aluminum NPT hose end fittings are precision-engineered fluid transfer components trusted by professional racing teams and performance builders across automotive, racing, and custom plumbing applications. Founded in 1955 by Earl Fouts, Earl's pioneered the use of aviation-grade fluid transfer technology in the performance automotive market — a legacy that continues today as part of the Holley family of brands.

The 45-degree angle configuration delivers essential routing flexibility for hose runs in tight or confined spaces, allowing builders to achieve clean, efficient plumbing layouts without excessive bends or stress on lines. NPT (National Pipe Taper) thread compatibility ensures these fittings integrate seamlessly with standard pipe thread connections across a broad range of fluid system applications.

Key Features:

• Lightweight aluminum construction — delivers an excellent strength-to-weight ratio without sacrificing durability or long-term reliability
• 45-degree angle design — optimizes hose routing in restricted or hard-to-reach areas for professional-quality plumbing results
• NPT thread compatibility — works with standard pipe thread fittings across fuel, oil, brake, cooling, and custom plumbing systems
• Precision machined — manufactured to tight tolerances for consistent, leak-free sealing performance
• Anodized finish — corrosion-resistant anodizing protects the aluminum and provides a clean, finished appearance
• Part of Earl's comprehensive AN plumbing system — designed to work in concert with Earl's hoses, adapters, and accessories for complete system builds
