#6 45 Deg. Tube Swivel

The #6 45 Deg. Tube Swivel by EARLS is an essential fitting for custom fuel, coolant, and fluid line routing in performance and modified vehicles. As a mechanic working with engine builds and fuel system upgrades, you'll recognize this as the connector that bridges rigid tubing with flexible hose runs at a 45-degree angle—critical for routing around tight engine bays, intercoolers, or relocated fuel tanks where straight fittings won't work. This swivel design eliminates stress on both hard and soft lines by allowing rotational adjustment without compromising system integrity or leaking under pressure.

EARLS fittings are renowned in the fabrication and motorsports community for precision engineering and reliability under high-flow conditions. The 45-degree angle swivel head permits fine-tuning of line orientation during installation, reducing fitting fatigue that occurs when hoses are forced into suboptimal angles. This particular model handles AN-6 connections (3/8-inch tubing), compatible with both alcohol and fuel-based cooling systems. The compact profile—just 3 inches in length and weighing a mere 0.06 lbs—makes it ideal for space-constrained engine compartments common in turbocharged builds, LS swaps, and fuel system upgrades where every millimeter counts.

Whether you're plumbing a custom fuel system, integrating an external fuel cooler, or rerouting coolant lines around a modified intake manifold, the #6 45 Deg. Tube Swivel eliminates guesswork and prevents premature line failure from torque stress. Install this fitting at any junction requiring non-90-degree approach angles to ensure both aesthetic cleanliness and mechanical longevity. Pair it with complementary EARLS fittings and tubing to build leak-proof, professional-grade fluid systems that withstand daily driving and track duty alike.
