#10 45 Deg. Tube Swivel

The #10 45 Degree Tube Swivel from EARLS is a precision-engineered fitting designed for custom fuel and coolant line routing in performance and modified vehicles. This swivel connector allows you to redirect tube runs at 45 degrees while maintaining a secure, leak-free seal—essential when fabricating engine bays with tight component spacing or unconventional layouts. Whether you're building a street rod, turbo conversion, or custom cooling system, this adapter eliminates the need for rigid elbows and reduces stress on hose assemblies during engine vibration and thermal cycling.

EARLS manufactures this swivel with high-grade aluminum construction and precision-machined internal passages to maintain unrestricted flow characteristics. The 45-degree angle geometry allows mechanics to negotiate space-constrained engine compartments without kinking or binding hoses, while the swivel joint itself permits a limited range of rotation—critical when aligning fuel rails, heater cores, or transmission cooler lines during final assembly. The #10 designation refers to the AN10 tube size (5/8-inch OD), a standard in modern fuel system and coolant applications rated for both carbureted and fuel-injected platforms. Anodized finish resists corrosion and provides visual clarity for leak inspection under engine heat and vibration.

Mechanics and fabricators rely on EARLS swivel fittings when custom-routing fuel systems, coolant loops, and transmission lines in engine conversions and restorations. The lightweight design (0.15 lbs) ensures minimal impact on vehicle weight while the compact footprint (approximately 2.85 x 1.15 x 3.8 inches) fits into tight bends where traditional rigid elbows won't work. Installation requires AN10-compatible tube ends and proper torque sequencing to prevent over-tightening; this fitting pairs seamlessly with EARLS hose assemblies and other aluminum fittings in modular fuel and coolant system builds.
