Twist-Lok Hose End #6 45 Deg Black

The Twist-Lok Hose End #6 45 Deg Black is a precision-engineered AN fitting designed for high-performance fuel, oil, and coolant systems in custom automotive builds and engine modifications. This 45-degree angled hose barb fitting serves as the critical junction between your hard-line fuel rail or pressure system and flexible hose runs, making it indispensable for builders transitioning between rigid and soft tubing in tight engine bay layouts. Whether you're installing a dry-sump system, aftermarket fuel injection setup, or custom cooling loop, this fitting ensures leak-free connections under pressure.

Constructed from aluminum with black anodized finish, the Twist-Lok Hose End #6 45 Deg Black features a 6 AN female port on one end and a 6 AN hose barb on the other, allowing it to accept standard -6 braided hose or thermoplastic fuel line while connecting to female 6 AN ports on fuel pumps, regulators, or manifold blocks. The 45-degree angle reduces stress on hose runs by eliminating sharp bends, improving flow efficiency and extending hose service life in demanding racing and street performance applications. The twist-lock design provides a secure grip on hose ends while the anodized aluminum construction resists corrosion and maintains structural integrity under high-pressure cycles, typical of boosted or nitrous-assisted engines.

Professional mechanics and engine builders rely on this fitting for custom fuel system plumbing, EFI conversions on classic vehicles, and multi-stage fuel delivery systems on turbocharged or supercharged platforms. The compact 2.65 x 1.85 x 4.9-inch profile fits easily in congested engine bays, and compatibility with standard 6 AN hose sizes ensures simple sourcing of matching components for complete system builds. Installation requires only a wrench to tighten the female port; the barbed end slides into pre-sized hose tubing with a light twist-fit grip that prevents unwanted slippage during vibration and thermal cycling.
